Here are two objects created for future illustration. The cup will be set with precious stones. The atmosphere is medieval style with an oriental touch. The subject is a treasure of an imaginary country. I'll make jewelry and money.

Very nice work Marcel, I like the crystal cap alot.

marcel · Post by **marcel** » 19 Feb 2012, 17:42

Thank jeffroig. Add emeralds and pearls to the cup and a temporary background to finalize materials.

What did you use for the crystal cap as I have several bottles to create.

bitkar · Post by **bitkar** » 20 Feb 2012, 10:14

great, nice to see you having such WIP

Here is a new object for the scene. I use the dielectric shader to fill glass with wine.

jeffroig · Post by **jeffroig** » 20 Feb 2012, 20:09

Very nice Marcel.
Is it dinner time yet, must have wine with your bread.

marcel · Post by **marcel** » 20 Feb 2012, 22:46

Test of negative light (green) + positive light (red) for the wine.

Draise · Post by **Draise** » 20 Feb 2012, 23:07

Textures and caustics are looking good! Very good. What does green light + red light mean? (i hope the answer is not obvious or i'll be kicking myself!)

Thank Draise.
There is no caustic. It is a simulation. the interest is to draw the caustic without investigating reality but rather a concern with art. I place the effect where i want even if it is not real. A personal touch, like a painter would. Also i don't need to cast shadow for the glass and don't use transparency shadows. I win a lot of computing time.
I use 2 local light, squarred falloff with distance:
- intensity with negative value to create a colored shadow (complementary color, it is why i use a green color).
- intensity with positive value to create a colored spot light (color of the wine).
It is also possible to ad a projector light with an appropriate image to create light of caustic more graphics. Maybe at the end, i will see that.

nice trick...

i like the materials... its always very essential to have welll set materials and good textures and bumps.

theuns · Post by **theuns** » 21 Feb 2012, 16:16

WOW!

Those reflections and shadows are AWESOME marcel!

Very well done...

trueSpace?

Draise · Post by **Draise** » 21 Feb 2012, 17:13

Great stuff! Thanks for sharing on the how-to! Very much appreciated. I was going to skip caustics renders with projector lights, but negativing intensity is an even better idea! I wonder if you can do that with GPU based DirectX lights....

Finis · Post by **Finis** » 21 Feb 2012, 22:00

Where are the negative and positive lights for the wine Marcel? Do they make the caustic effect?

I used negative intensity projector lights to put the petroglyphs on my Blades Magazine rock.

marcel · Post by **marcel** » 22 Feb 2012, 07:34

@ Theuns : yes trueSpace. Model side and Lightworks render engine.
@ Finis : in reality caustics create light but also shadow around that do more contrast. Here the negative light create dark zone around the red zone on the floor.
Now I ad a projector light with a "caustic image". It is just a graphic problem to resolve.

A new object for the scene.

Draise · Post by **Draise** » 24 Feb 2012, 20:27

FANTASTIC!!!! Love yoru textures! Will you give us hints as to how you shade it so succesfully rusticly golden?? Oh oh, and did you use a displacement map on the sphere? Or is it just a bump? Very nice model!

marcel · Post by **marcel** » 24 Feb 2012, 22:36

Hi Draise.
The metal is made with the multilayer paint shader. Flake type : gold and hight value for metallic option. I ad also another layer with a texture map (photo) and a leather displacement to dirty up the effect. The globe is a simple bump map with a good image with real elevation from the Nasa. Render with Lightwork on model side. No simulation of caustic at this time. Maybe later.
Here is an update of the object because some leaves was hidden at the last render. The globe is a little bigger.

MikomDude · Post by **MikomDude** » 25 Feb 2012, 02:04

I'd love to see a wireframe of your golden globe(no pun intended). This is most impressive indeed!

marcel · Post by **marcel** » 25 Feb 2012, 10:01

Here is a wireframe and an update of the globe.

BNG · Post by **BNG** » 25 Feb 2012, 12:22

Wow...Marcel you truly are an inspiration for us all. I love your work bro!

marcel · Post by **marcel** » 25 Feb 2012, 19:40

Thank BNG.
I worked on the ambiance.

Finis · Post by **Finis** » 25 Feb 2012, 20:33

Great designs!

I think the blue pearls and blue glass look too much alike. They are too similar in color ... unless it is supposed to be like that to show some association or connection between these items.

Jimmer · Post by **Jimmer** » 27 Feb 2012, 13:36

WOW ! ! ! Very nice as is....

Draise · Post by **Draise** » 27 Feb 2012, 19:14

Is the last image the final render? i had a look at your website and it looks great! Keep it up!

theuns · Post by **theuns** » 27 Feb 2012, 19:34

WOW!!!

That globe is gobsmacking awesomeness, marcel!!!

Would you consider making a tutorial to show us mere 3D mortal how you did it??? How the boomstick makes magic?

marcel · Post by **marcel** » 27 Feb 2012, 22:49

@ Finis : yes the glass is too blue. I reduce the color. Thank.
@ draise : My web site is not updated since a few years and i need to change it. More simple with Less sample but better quality.
It is not the final image, here is the next step ...
@ Theuns : some wire for the fun.
ad windows, diamonds and rings for the final image.

marcel · Post by **marcel** » 27 Feb 2012, 22:56

Some details : rings, exploded carafe to see the structure of the 3d. Many polygon because it is for a hight definition image.
The "caustic map" is used with the projectors.

marcel · Post by **marcel** » 27 Feb 2012, 23:27

HD does not support imperfection. I need to resolve every detail, even the smallest. I need to think otherwise than through the screen. Zoom don't destroy textures. It is very important. Here is two details ...

marcel · Post by **marcel** » 28 Feb 2012, 16:43

Final render here :
vi ... f=6&t=3311

Fantastique!

Beautiful job Marcel!

marcel · Post by **marcel** » 01 Mar 2012, 17:23

Thank all! It seem that old man who use old pc and old software can still be used for something.

Tnx for sharing marcel, they look stunning. High detail models there. Were all the fine detail made by hand? Like the base of the globe? Lovely!

Will you share some of the material and shaders settings you used to get those gorgeous items with the reflection?

bitkar · Post by **bitkar** » 06 Mar 2012, 23:53

awesome... looks real, jawdroping... the best i saw from you

RAYMAN · Post by **RAYMAN** » 08 Mar 2012, 21:28

The more I look at the mesh the more it looks like the new flow command !:?:
Am i right ? If not .... you got the software look at it it does these things pretty well......
