Did not like this idea?

Also maybe add a On/Off button that sets a minimum amount for the PST = On,
and sets to Zero = Off.

This would give a definite clue how to start and stop it

Render passes so far. Section on left is the pass channels, right side is the passes available to use in the channels.

Still a few more controls to add for toon effects and edge attributes.

Wow! I think you broke a trueSpace76 record for the biggest panel in it's history!

That should make it easier.

Do you have a suggestion for a minimum value for the Save Time?

Here is a couple pdfs of the install and toolbar to look at.

new mega render pass panel

"New Render Passes: Basic Toon effect, Object Edges and Faces Edge"
scrubber control for partial save timer

Render pass panel usage:
ambient occlusion and z-depth have simple dropdown selection
right click a channel on the left to assign the default pass to that channel
or
1. select one of the channels on the left using the radio buttons
2. click on one of the buttons on the right to assign that pass to the selected channel

Using the Bucket Rendering new scrubber's values is causing the PST timer to stay on and not work as expected. IE: Rendering... stuck meassage.

How complex is the scene you are rendering. What value did you set for the timer. Did the render complete or is the only problem the stuck message? While rendering did you see it as it updated or only the final image? do you have more than one instance of truespace running? Did you try restarting the computer?

No way to reproduce without more information.

Edit: also forgot to ask is it patched or no patched, full or std version?

I think it was user error again by entering wrong values in Time Save.
I had at one point two consoles running in the background and the PST timer was not shutting off.

Enclosed is an update.
Changes:

Tile Size's edit control
Change on update

Time Save
Changed the Edit box to zero decimals.
Add a Off/On button

Edited the Render Pass panel
Edited the Render Pass's Window Frame

Changed the YafaRay4tS toolbar Volume button's help Text

Edited the YafaRay4tSv090 Installation Instructions.txt to match the YafaRay4tS Help file.

New YafaRay4tS Help.chm
Please take a look and help me with the ? marks.
And or any other changes needed.
There is a blank Procedurals.htm page at the end of the help file. Was not sure it will be needed or not.

I think I made a mistake with the Yafaray Settings RMB Command.RsObj by adding an exclamation to the
if(!Node.Exists("/Yafaray Folder")){ line.

Code: Select all

	if(Node.Exists("/Offline renderers/Yafaray")) {
		var myenum = System.CreateDO("Common Data Package/String Enum Data");
		myenum = Node.Value("/Offline renderers", "Renderer");
		var str = myenum.GetSelectedString();
		myenum.SetSelectedString("Yafaray");
		Node.Value("/Offline renderers", "Renderer") = myenum;
	}
	if (Node.Exists(Space.CurrentScene()+"/YafaRay4tS")){
	} else {
		if(!Node.Exists("/Yafaray Folder")){
			Node.Copy("/Yafaray Folder/YafaRay4tS", Space.CurrentScene());
		}
	}
	UserInterface.OpenToolPanelViewEx2("" , "" ,Space.CurrentScene()+"/YafaRay4tS", 6, 1, 0)

My thought was that the YafaRay4tS.RsObj should not be replaced, given that if a user had a scene with their settings in place, it would be a problem. So the way it is now, if there is no YafaRay4tS.RsObj in the scene, it will not be created. Thats not good either! Please take a look.

That code will not do anything. It exists inside the YafaRay4tS node. If it doesn't exist then it won't run. If it does exist then

Code: Select all

if (Node.Exists(Space.CurrentScene()+"/YafaRay4tS")

My thought was that the YafaRay4tS.RsObj in the scene should not be replaced.
The user could lose all of their settings.
Looking at your Save Settings script it looks like you are copying all of the Attributes from the one in the scene to the backup?
Verses deleting and replacing the one in the scene?

That's right. So are you saying you want to use the RMB to copy settings from the scene to the backup? or maybe if you just define for me what the RMB is supposed to do.

trueBlue · Post by **trueBlue** » 19 Jul 2018, 23:46

Okay I tested again with Vray and YafaRay4tS loaded.
I restored the Yafaray Settings RMB Command.RsObj by putting the exclamation back in.
It does not replace and or change the setting in the existing YafaRay4tS.RsObj in the scene.
So my concerns are squashed.
The Yafaray Settings RMB Command.RsObj Switches to yafary as the renderer.
I added more code to also load the YafaRay4tS.RsObj into the scene.
I also uploaded RC-18 with the changes mentioned above.

Code: Select all

// Switch to Yafaray
	if(Node.Exists("/Offline renderers/Yafaray")) {
		var myenum = System.CreateDO("Common Data Package/String Enum Data");
		myenum = Node.Value("/Offline renderers", "Renderer");
		var str = myenum.GetSelectedString();
		myenum.SetSelectedString("Yafaray");
		Node.Value("/Offline renderers", "Renderer") = myenum;

Some notes for the docs
All ? entries answered if I could find the answer.

Export XML - creates an xml file without actually rendering
Render XML - renders the custom xml file or the last xml file that was generated
-------------------------------
Render Settings
Input Color Space - ?
LinearRGB - ?
sRGB - ?
XYZ - ?
-------------------------------
Background
Casts Shadows - background light casts shadows

Image HDRI/IBL
Smart Blur - "* Added SmartIBL functionality to reduce noise when using World HDRI textures for lighting. The functionality adds a new parameter "SmartIBL blur" that blurs the World texture used for lighting without affecting the world texture used for reflections, etc. High values can cause slowdowns at render process start."

Sun Sky
Sun Casts Shadows - sun sky casts a shadow

Night - "This feature renders the scene at night, with the Sun acting as the Moon."

Caustic Photons -
Diffuse Photons - "* Ability to enable/disable Caustic and/or Diffuse Photons generation in the Photon Map integrator."

Samples - " Samples for both the Sun and the Skylight. The more samples the less noise and the better glossy reflections, but the more render time as well."

Color Space - ?

Exposure - ?

Brightness - "Sky Brightness: Independent brightness control for background sky colors; it does not affect amount of cast light."

Altitude - "With this setting, we can give the camera a different altitude relative to the background center. If Altitude increases, the background horizon lowers. This option can be useful to render objects from a camera which is above the ground level, while still getting a correct position of the background horizon."
------------------------------------
Animation
Set From Timeline - set render start and end based on the animation view start and stop frames

Set From Keyframes - set render start and end based on the keyframes in a scene or the keyframes on the selected object in object render mode

--------------------------------------
Photon Mapping
Search - "User can specify a desired number of photons. It guarantees that there are K photons in the measurement. The more photons are used, the smoother the estimation will be. If too many are used, the estimation will tend to be blurry, while too few gives a splotchy appearance (low frequency noise). Interpolating 50 to 150 photons is often a good choice."
Photon Map Processing - see above
----------------------
Pathtracing
Min Bounces - The relevant parameter will be "russian_roulette_min_bounces".
- If this parameter is set to 0, russian roulette will be enabled.
- If set to the same value specified in depth (max bounces), russian roulette will be disabled
- If set to a value between 0 and max bounces, then russian roulette will only start be applied after this number of bounces, so we can get decent sampling in dark areas for example and get a good speedup with less noise.
- Lower values of this parameter will result in faster (but somewhat noisier) renders.

Use Anisotropic Specular - "which means that reflection is not equal in all directions"
"the exponent value is divided into vertical and horizontal components. By using a different value for each component., the reflection will take an anisotropic oval shape."

U Exponent - horizontal exponent value

V Exponent - vertical exponent value

Receive Shadows - surface will have shadows cast upon it

Visibility - invisible is not visible in the render, reflections and shadows remain

Additional depth - add to the render settings ray depth for this material - "* Ability to set a per-material raytracing depth, for example to speed up scenes with glass."
---------------------------------------------
"Coated Glossy is basically a glossy material (see the previous section) with some kind of reflective coating layer on top. IOR is the setting that controls reflectivity of the coating top layer. This reflective layer can produce caustics. It is a good material for car paint."

Thanks!

Trying to redefine the info in the AA and General Settings from the XML Scene specs.
This what I have so far:

-- Anti-Aliasing Settings –
Filter - 3 Anti-Aliasing reconstruction filters to use when resampling.
- Gaussian - Slight blurring.
- Mitchell-Netravali - Improves sharpness of the edges.
- Box - Equal weighting of all samples.
Min Sample - Number of samples to use on first Anti-Aliasing pass.
Pixel Width - Width of Anti-Aliasing pixel filter. [0-8]
Passes - Maximum number of Anti-Aliasing passes.
Inc Sample - Number of samples for additional Anti-Aliasing passes.
Threshold - Color threshold for additional Anti-Aliasing samples in next pass.
-- General Settings –
Ray Depth - Amount of times that rays can be reflected in specular surfaces or pass through transparent surfaces.
Transparent Shadow depth - Amount of transparent surfaces that shadow rays can get through to find light sources.
Gamma In - The default gamma value for all colors, lights and textures.
This value is used to convert these values to linear color space used by the Yafaray renderer.
Gamma Out - The gamma value target for the rendered image.
CPU Threads - Number of CPU threads used by YafaRay.
This number should be equal to the number of CPUs in your computer or minus one if you find that using all the CPUs bogs down your computer.
Normal Shadows / Transparent Shadows - Switches from Normal to Transparent Shadows.
Save Alpha - Exports an alpha file in addition to the RGB output file.
Z - Channel - Enable the Depth Channel in the output file.
Clamp RGB - Color depth is reduced to a low dynamic range before Anti-Aliasing filtering.

Seems to me that the info on Gamma In and Gamma Out is incorrect.

-- General Settings --
Gamma In - The default gamma value for all colors, lights and textures.
This value is used to convert these values to linear color space used by the Yafaray renderer.
Gamma Out - The gamma value target for the rendered image.

Blender user guide
Output Gamma.
Gamma correction performed on render output to match gamma of the color space the image is inserted in, usually 2.2 for sRGB or linear for HDR. This setting is by default set not to perform gamma correction (gamma output = 1) in order to pass renders in linear space to the Blender Compositor. More information here.
Input Gamma.
Inverse gamma correction performed on render input, which are textures, shader colors and light colors, so the render engine can work internally using the linear space. Gamma input value should equal that of the color space the input is working on, usually 2.2 for the sRGB

Also is the Linear Workflow in YafaRay the same in YafaRay4tS?

Found a way to Close TGA Viewer and Delete the Yaf_render.cmd file
Edit: Ugh, deleting the Yaf_render.cmd is not compatible with the viewers in Animations.
RenderFnSet

Code: Select all

Line 188 = Activity.Run(System.ThisOwner() + "/Close_TGA_Viewer")

var P = EP.item();

}

Can not figure out how to do the same with the Internal Viewer and OptDetector Viewer.

Also discovered by accident that you can use the Custom Viewer to open an Image editor with the rendered image. I have TGA files associated with GIMP. So I entered
C:\trueSpace761\tS\Image Folder\yaf_test.tga
in the path for the Custom Viewer.

1.) If Use OptDetector Viewer is enabled and Use Internal Viewer is not enabled, the OptDetector Viewer does not work. Any chance this can be fixed?
2.) I notice that the DEFAULT settings for the following items are different from the YafaRay XML scene parameters, recommended defaults.
Background - Image
ibl_samples [8] (preferred) number of samples for direct lighting
Direct Lighting
raydepth [5] (preferred) maximum depth for recursive raytracing

Almost finished with the YafaRay4tS Help file.
I have searched in vein trying to figure out the Input Color Space's options in YafaRay4tS. I do note that in one of the previous YafaRay releases just before 3.3.0, notes that the Input Color Space was changed with regards to sRGB vs linear RGB and there is zero information on the XYZ.
Quote YafaRay developer:

From now on the user will be responsible for selecting correct ColorSpaces for all textures, including bump map, normal map, etc. For example for Non-RGB / Stencil / Bump / Normal maps, etc, textures are typically already linear and the user should select "linearRGB" in the texture properties, but if the user (by mistake) keeps the default sRGB for them, YafaRay will (incorrectly) apply the sRGB->LinearRGB conversion causing the values to be incorrect. However, I've added a "fail safe" so for any "float" textures, bump maps, normal maps, etc, when getting colors after interpolatio YafaRay will to a "inverse" color conversion to the original Color Space. This way, even a mistake in user's color space selection in bump maps, normal maps, etc, will not cause any significant problems in the image as they will be converted back to their original color space. However, in this case rendering will be slower and potential artifacts can appear due to interpolation taking place in the wrong color space. For optimal results, the user must select correctly the color space for all textures.

Default
Input Color Space - ?
LinearRGB - ?
sRGB - ?
XYZ - ?
Any suggestions on what to say in the help file?

Also need your help with the following items:
...........
Texture Map
1.) Shouldn't the color be white for use of Alpha in images?
User Guide - Texture Input:

YafaRay 8-bits supported formats are tga, jpeg and png. YafaRay also supports 16-bits tiff, exr and hdr.
Input Color Space: Use sRBG for 8-bits formats and Raw for high dynamic range formats.
UseAlpha: Renders the texture alpha channel as transparent (if it exists), white otherwise. Enabled by default.

2.) I notice that the DEFAULT settings for the following items are different from the YafaRay XML scene parameters, recommended defaults.
Background - Image
ibl_samples [8] (preferred) number of samples for direct lighting
Direct Lighting
raydepth [5] (preferred) maximum depth for recursive raytracing
...

I don't think the XML parameters are up to date. It has render threads >0 but value of -1 means use all threads, no mention of render passes. As is now the defaults are setup to match what Blender shows for it's defaults.

Almost finished with the YafaRay4tS Help file.
I have searched in vein trying to figure out the Input Color Space's options in YafaRay4tS. I do note that in one of the previous YafaRay releases just before 3.3.0, notes that the Input Color Space was changed with regards to sRGB vs linear RGB and there is zero information on the XYZ.
Quote YafaRay developer:
From now on the user will be responsible for selecting correct ColorSpaces for all textures, including bump map, normal map, etc. For example for Non-RGB / Stencil / Bump / Normal maps, etc, textures are typically already linear and the user should select "linearRGB" in the texture properties, but if the user (by mistake) keeps the default sRGB for them, YafaRay will (incorrectly) apply the sRGB->LinearRGB conversion causing the values to be incorrect. However, I've added a "fail safe" so for any "float" textures, bump maps, normal maps, etc, when getting colors after interpolatio YafaRay will to a "inverse" color conversion to the original Color Space. This way, even a mistake in user's color space selection in bump maps, normal maps, etc, will not cause any significant problems in the image as they will be converted back to their original color space. However, in this case rendering will be slower and potential artifacts can appear due to interpolation taking place in the wrong color space. For optimal results, the user must select correctly the color space for all textures.
Default
Input Color Space - ?
LinearRGB - ?
sRGB - ?
XYZ - ?
Any suggestions on what to say in the help file?

...

Nope, only that XYZ is "experimental".

Also need your help with the following items:
...........
Texture Map
1.) Shouldn't the color be white for use of Alpha in images?
User Guide - Texture Input:
YafaRay 8-bits supported formats are tga, jpeg and png. YafaRay also supports 16-bits tiff, exr and hdr.
Input Color Space: Use sRBG for 8-bits formats and Raw for high dynamic range formats.
UseAlpha: Renders the texture alpha channel as transparent (if it exists), white otherwise. Enabled by default.
...

I don't know what you mean here. Quote doesn't have anything to do with user setting a color. If there's no alpha it renders as white.

Thanks but I was hoping for simple steps on how to use your Blend material.
I asked for 'Steps to create 3 blended materials', because your Blend Material Collection object looks like it supports 25 materials.
So what is not clear is how to use your Blend material with the required Blend Material Collection object.

Also when Color is checked for your Image Cloud.

If you want me to take a look a complete set of steps to reproduce the problem would make it much easier.

trueBlue · Post by **trueBlue** » 25 Jul 2018, 19:28

Those were the steps that I used.
However, I rebooted my computer and tried again and it worked as expected.
Until I started using the Render Object icons.
Which I am now discovering anaother issue.
The YafaRay4tS toolbar Render Object seems to be rendering twice.
If nothing is selected, I get two identical errors.
If an object is selected, the Internal display flashes twice.
I suspect that when you switch back and forth with the differnt Object Render modes, something is getting messed up.
I also see that neither Render Object mode in the Default aspect are enabled after switching to one or the other and rendering.
When I use tS Render Object icon is where I got the rendered image with zero bytes.
I also note that it does not render twice.
Can not really narrow this down to when or how this happens because sometimes it works right and sometimes it does not.

So something with the combination of switching Object Render modes, Render Object icons, and using the Blend material without any material applied.

Now it seems like the Object Render mode is stuck in the experimental mode. Selecting the default mode is not working like it should. IE It is working like the the experimental mode.

Do not know what to say Clinton. I did confirm in the console that YafaRay did not recognized the Blend material several times and rendered an image with zero bytes.

YafaRay4tS toolbar Render Object LMB command
OfflineRender.OpenView('',0,0);if (Node.Exists('/Scripts/Commands/RenderObject')){Activity.Run('/Scripts/Commands/RenderObject');}if (!Node.Exists('/Scripts/Commands/RenderrObject')){OfflineRender.RenderObject('')}

tS Render Object LMB command
OfflineRender.OpenView('',0,0);Activity.Run('/Scripts/Commands/RenderObject');

Looks like the typo snuck back in with the
YafaRay4tS toolbar Render Object LMB command
RenderrObject <----- two r(s)

Yep, that happens sometimes especially if you're testing different versions of tS or even switch computers.

What I mean by steps is a play by play of everything you did.

1. started a new scene
2. right clicked this toolbar for yafaray
3. added yafaray lights
4. added a cube and assigned blend material to it
5. pressed the render button
after pressing render I expected this to happen but that happened instead

No details translates to ok let me try this...nope don't see the problem, let me try this instead...nope let me try this instead...again..............1 or 2 hours later ok now I see the problem! or I give up I don't see a problem so it never gets fixed.

It renders correctly though.

Wonder if you were to use a InputBitmap from the Components - Inputs and compilers library instead of the path dependent file dialog that you are using, would solve this issue? Instead of using the file dialog a user Ctrl + LMB selects the Bitmap control to select an image. This is the way all of the compiled D3D material are, as I understand it. Or is the path to the image needed by YafaRay?

Here is one without the errors.
I went inside the objects and changed the paths.
I change the color and enabled transparent shadows.
Had to replace the YafaRay4tS again as I discovered the errors stay with it regardless if they were corrected.

I ran the Prep YafaRay Scene script.
I got a message that it was successful from the script.
I got the first error that I posted when I rendered.
Then I replaced the Yafaray4tS.RsObj
Then I got the path errors.

My guess given the error is the differences in the old YafaRay4tS node in the included scene and the newer one installed? Most likely the old one does not have the Object Render mode.

Tested
downloaded the original demo blend scene
downloaded and unzipped the texture files
opened the scene file and pressed the Prep YafaRay Scene, Start button
tried render got the error
ran render directly from the YafaRay node

got error message about textures
the wood texture was missing from the render
message from Prep YafaRay scene is wrong - said all was ok even though didn't select the textures downloaded

pushed the Choose Texture Source Folder button and chose the textures downloaded
pressed Start an got the same positive message
ran the render from the YafaRay node

Some Blend Material notes:

Blend Material Collection - repository of stand alone materials used inside of a Blend Material. It comes pre-populated with 2 materials since you need 2 materials to make a blend. 3 or more materials cannot be blended together. Use the Add Material button to add more selections for blending. There is no way to remove a material slot once it has been added. The Reset button clears out the collection and reverts back to the 2 blank materials. The Blend Material must have a Blend Material Collection in the scene, otherwise it has no materials to blend between.

YafaRay Blend Material usage:
1. first add a Blend Material Collection to the scene
2. edit 2 of the materials inside the Blend Material Collection
3. if more materials are needed press the Add Material button
4. assign the YafaRay Blend Material to the geometry
5. press the Update Material Lists button to refresh the 2 lists below it
6. choose 2 materials for blending from the 2 drop down lists
7. press the Make Preview button to see a D3D viewport preview for the Blend Material
8. control the amount of blend between the 2 materials using the Blend slider
9. to control the blend with a texture press the T button - this will override the Blend slider

Well at least for me.

I was turned off by the use of the OptDetector as a viewer because the plugin demanded to reload it's libraries after you Reset the Default Context.
I discovered a OptDetectorsPreferences node in Preferences.
I saved it to the preobjects folder and added a line to the reset.js file.

Code: Select all

RsFileIO.LoadObject( rosDir + '\\scripts\\preObjects\\OptDetectorsPreferences.RsObj', '/Preferences/');

No more demanding that the libraries are reloaded!

Thanks! Getting closer to understanding your Blend material.
Following your steps I did run into an error.
Also had a couple of instances where only one of the two materials was created.
I did not document it be will try again today.

1. Add
Node.Select(copySphere)
MeshModifiers.OpenMaterialEditor()
to the Run script.

2. Add Select Material 1 Button Control
Node.Select('%THIS_NAME%/BlendMaterial1')
MeshModifiers.OpenMaterialEditor()

3. Add Select Material 2 Button Control
Node.Select('%THIS_NAME%/BlendMaterial2')
MeshModifiers.OpenMaterialEditor()

4. All the primitives have their Render Attributes and Mesh nodes set to not show in the panel.

Blend material
Modifications:
Add script that automatically runs on load

Code: Select all

if(!Node.Exists(Space.CurrentScene() + "/Blend Material Collection")) {
RsFileIO.LoadObject(System.GetMainDir() + '\\Rs Main Libraries\\YafaRay Materials\\Blend Material Collection.RsObj', Space.CurrentScene());
}

Not sure yet, still learning, there might be a problem with the Combo Controls and or the need to have the selection in the control select it's node. Or not.

To use the only requirement is to have the new Blend Material Collection.RsObj in the YafaRa4tS Materials library.
Let me know what you think?

This is true but at least it is a start in blending two materials.
You could add an instruction after selecting the Select Material 1 button, to use your keyboard arrow keys to navigate to the BlendMaterial # wanted.
If you created a Combo Ctrl that gets populated after each addition and a button that selects it would be much better.
Even better a Watch Dog that selects automatically.

I signed up at the YafaRay user’s forum and asked about Input Color Space and Background Color Space. Here is the reply:
Quote - David Bluecame:
“Keep in mind I'm actively working on a significantly modified upcoming yafaray v4 that will have a more clearly defined API to be more compatible with 3rd party software, using either XML files, Python3 or directly interfacing with YafaRay interface C++ API.

The reason of those differences in the Color Space are historical. The Background was developed by other developers and the Color Space settings they included in the Background were only used for it but not for the rest of the software.

Around 2-3 years ago I introduced Color Spaces in the rest of the software but, to be honest, did not dare to mess around the Background color spaces code so I kept it "separate" with its own Color Space code and parameters.

I agree it would be ideal to have a single Color Space model for the entire renderer, including Backgrounds. I will have to study how the background code works and I will try to unify this in the upcoming v4 if I can...”

Quote - David Bluecame:
“About the color spaces in the general renderer, there are actually 4 options:

* Linear RGB: in this mode, the colors are taken "as is" without any processing. For example color R=0.5, G=0.5, B=0.5 would be written in a "low dynamic range" such as PNG the following way: R=127, G=127, B=127 and vice-versa

* RAW / Manual Gamma: in this mode a Gamma value can be specified and the color values are transformed using the specified gamma value.

* sRGB: this mode is somewhat similar (but not the same) as a RAW Manual Gamma with gamma 2.2. However the sRGB standard is not exactly a gamma curve and has two segments (one linear and one exponencial). The difference is subtle but for color accuracy this is normally necessary when using PNG, JPG, etc.

* XYZ: this is experimental (and possibly not correctly implemented?)”
End Quotes

Changes to Input Color Space implemented last year:

Input Color Space
You can read the code here:
C:\Program Files\yafaray_v3\include\yafaray\core_api\color.h

Background - Color Space
You can read the code here:
C:\Program Files\yafaray_v3\include\yafaray\utilities\ColorConv.h
Within the code follow the link:
http://www.brucelindbloom.com
Everything you ever wanted to know about color from a color scientist.

So this is what I purpose:

Default
Input Color Space - Color processing options for all textures.
LinearRGB - Linear with no color processing. [Legacy]
sRGB - Color processing with Gamma 2.2. [Recommended]
XYZ - Matrix color processing. [Experimental]

Background
Color Space - Color processing options for the Background.
CIE (D50) - ?
CIE (E) - ?
sRGB (D50) - ?
sRGB (D65) - ?

Exposure - Lighting multiplier.

Matrix color processing was a total guess, actually all were.

You could add an instruction after selecting the Select Material 1 button, to use your keyboard arrow keys to navigate to the BlendMaterial # wanted.
If you created a Combo Ctrl that gets populated after each addition and a button that selects it would be much better.
Even better a Watch Dog that selects automatically.

I agree but I would like to see if another option is feasible first.

I redownloaded the scene and it worked.
Must have fiddled with the scene in question that disappeared, while watching IT Crowd.

Testing Input Color Space and logging the results.

All three of them are being logged has being used on another line.
XYZ gives a yellow hue to the image.

YafaRay4tS materials do not have a texture property to set diiferent flavors.
Is that even possible on per texture basis?

In Blender those 3 values are set on the scene not on the individual textures, unless you mean something else by "flavors".

New Blend Material Collection:

replaced the YafaRay Blend Material in the Collection - Blend materials can't be blended in trueSpace. only simple materials can be blended together
locked the transforms of all the elements except for the main flat surface. it can be used to move and size the collection in the 3d view
added an active checkbox - turns on selection processing

select the "plus button" in the 3d view to add a new material to the collection

to edit a material:
select a material sphere or it's label in the 3d view then use the eyedropper tool that appears to load it into the material editor

clintonman wrote: 27 Jul 2018, 07:03 select the "plus button" in the 3d view to add a new material to the collection

Is there a reason why this has a YafaRay Blend material?

1.) If you have this Active and you select you keyboard Right -> arrow key, it adds more materials to the collection.

2.) Also when it is Active and you inspect material 1 & 2, the Shinny Diffuse material that they have does not show in the Material Editor. The material 1 & or 2t is being selected then the Blend Material Collection gets selected.
If I select material 1 & 2 without it being Active, the material does show in the Material Editor.

The Inspect tool is kind of weird in the way it works.
Open up the Command History and use the Inspect tool, to see what happens, using different objects with different material. Watch for the last selected object getting selected after exiting the Inspect tool.

I think what is happening with your project (Active or not Active) is the Blend Material Collection's material is being inspected and not the Sphere's material and or material 1 & 2.

You cant assign the YafaRay Blend material to the items inside the Blend material collection.

I'll have to get back to you on that. I noted one change but it was to RC19 which was released twice. Don't know if I have the new RC19 or the old, so need to re-download.

trueBlue · Post by **trueBlue** » 29 Jul 2018, 00:22

Okay thanks!
I never applied that update.

With regards to YafaRay materials:
Is the 'Alpha preview is inactive' button just for Transparency?

At the bottom of the YafaRay materials there is a 'D3D Preview' button.
Is that just for the Bump?

Also there is Receive Shadows.
Is that have anything to do with the Render Pass or is it for the material, or both?

Never have used Render Pass.
Do the attributes at the bottom of the materials that are for the Render Pass, need to be shown on the material interface?
Or are they per material settings for Render Pass?

Blend Material Collection

: Capture.PNG (3.43 KiB) Viewed 4839 times

Add Material button
Adds a new material Egg, selects it, opens the ME, and Inspect tool to inspect and paint.
I have the Blend material set to automatically load the Blend Material Collection into the scene, if it does not exist, open it's floating panel, reset the D3D Material Editor's default material.
Note: Reset ME material is for removing the Blend material from the ME.

Select Material button
Selects the BlendMaterial# in the Material combo control, opens the ME, and Inspect tool to inspect and paint.

Cube, Plane, and Text are locked down.
All objects have their inner panels set to not export. Show in the Stack.
Sphere, BlendMaterial1, and BlendMaterial2 have Edit controls for setting notes. IE material descriptions.

Workflow
With your object selected, Load the Blend material. The Blend Material Collection loads into the scene, selects the BlendMaterial1, and opens the Inspect tool.
Inspect and Paint that Blend material.
Select BlendMateral2 from the combo cntrl and press the Select Material buton.
Inspect and Paint the Blend material.
Inspect your object and press the Make Preview button.
Adjust the Blend amount and your done.

You can now delete or save your collection.
If you add another material to the collection, press the Update Material List button.

Removed due to update

Re uploaded RC -19 in the previous post.

Here is a scene that shows that YafaRay does not recognize the Blend material when there is no materials applied.
Check the console.
Fix - update system trace error message to the new error handling system
YafaRay4tS/MaterialsFnSet around line 1382
Code: Select all
function ExportBlendMaterial(MaterialNode) {
	var Errors = Node.AccessFnSet(System.ThisOwner() + '/ErrorsFnSet');

		//System.Trace("Error: Blend Material Collection not found. Skipping material export.");
		Errors.Add("Blend Material Collection not found. Skipping material export.");
		return;
	}

Paint object with Blend material and render.
Error Found

Repaint object with other YafaRay material and render.
Error Found

: Blend Error.PNG (4.16 KiB) Viewed 4761 times

Work around
Replace YafaRay4tS.RsObj in the scene with a new one.

Is there a way to clear Errors Found in your new errors handling system after they are created?
I notice that in ErrorsFnSet you have:

Code: Select all

function Clear()
{
	message = '';
	IndexOfPolyFill();
}

Maybe run that after an error is found?
If not maybe you can give instructions in the error message on how to rectify the above issue.

Only PassID is used for render passes and it's per material. The other attributes are for render control, but do not use the render pass system. If you make a simple scene and look at the xml file you can see those attributes belong in the material.
