Yafaray4tS v0.9.0

[trueBlue]

Lights are ready.

Changes:

Changed attenuation values for ies light, spotlight, point light, sphere light and area light
changed default power for some lights
Changed the power multiplier in the preview:
ies light = 4 * sqrt(power)
spotlight = 4 * power
pointlight = 2 * power
spherelight = 2 * power * scale
arealight = power * (scaleX + scaleY)/2

sphere size exports the scale value instead of the size attribute
new integrated ies light generator - GenerateIESprofileScript node in YafaRayFolder not used anymore

Testing the Resets
Want to confirm that this is correct or not.
Infinite, Point, and Area 'Cast Shadow' - Reset is unchecked?
Sun and Sphere 'Cast Shadow' - Reset does not Reset checked or unchecked?
Directional, Spot, and IES Spot 'Cast Shadow' - Reset is checked?
Directional 'Size' Reset is 0.785

If it is important I can put a jScriptObject in between.
params.Param('vtData') = true;

In your ToDo list before you released the Lights, you mentioned that the Size attribute needed to be added to the Default aspect on the Sphere light. It is not there. Do you want me to add it?

Nope, "sphere size exports the scale value instead of the size attribute", so size isn't read by the exporter anymore.

YafaRay4tS updates today

changed default solid color background to trueSpace blue

altered the Yafaray Node Camera defaults to angle=90, max angle=90, mirror=false, circular=false

added a valid texture file type check to the materials, specifically the Map node

added an error system to the render process - now just has the same valid texture check as the materials

next need the same texture checks for animation render

Hi Clintonman and trueBlue...

while I admire your hard-work on this plugin I would like to know if there is a comparision scheme "vRay vs YafaRay" (tSp versions).

The question : will YafaRay-renders be better of vRay-renders ?

Hi Clintonman and trueBlue...

The question : will YafaRay-renders be better of vRay-renders ?

Here is a quote from one of the original creators of YafaRay4tS

...

As far as comparison goes, I'd say that a big advantage for YafaRay is that it's glass material actually works, where as tsVRay has some problematic bugs related to glass. On the other hand VRay is definitely faster and has an SSS shader.

As far as render quality goes, it's really about learning the render engines. You can do professional work in both.

This was a comparison of an older version of YafaRay. I don't know how VRay compares to the newer version of YafaRay and I don't know if the glass problem in VRay was ever addressed.

Thanks a lot...fast and clear answer...as usual!

Putting together a trueSpace Update 4 with YafaRay4tS beta, which will include new trueSpace lights with your Color Picker, new Yafaray toolbar, and new Yafaray libraries. Most likely very late tonight or early tomorrow.
Do you have a trueSpace version of your new IES Spot?
Guessing but it looks like I can remove the Yafaray stuff from the Yafaray IES Spot and that would work with tS?

[clintonman]
