I've always thought the sparkling texture used on this model was really pretty and unique. I was wondering if there was a way to recreate this in Maya or another program. Lucky enough, the artist also posted part of her work process on this model (seen below).
For this model, the artist used ZBrush for rendering and Adobe AfterEffects for compositing.
The following descriptions of each render phase in the image above are from the artist:
"1. the basic color material - a modified version of the "cb silver pearl" material from the pixologic matcap library. this is the basic layer on which everything else is layered.
2. environment reflection - the flat material with a "light probe" texture assigned to it
3. directional color - the flat material with a texture made in photoshop ( a slightly distorted rainbow gradient) it is used to create the overall color of the skin
4. directional mask - the flat material with a spherical black to white gradient - used to mask in the sparkling effect
5. shadow pass
6. ambient occlusion pass
7. alpha mask
8. depth mask - with an added disc mesh (under the feet) to keep the depth values consistent throughout the turntable
9. model-parts mask
10. 11. 12. three different noise textures on the flat material - these are used to create the sparkling effect"I couldn't find a "cb silver pearl" texture in Maya but I'm sure one could obtain it through files from ZBrush. I'm a bit confused as to what a "light probe" is in Maya even after research. Everything else seems to be possible in Maya or Photoshop and the last three passes were added in AfterEffects. This process turned out to be more advanced and harder to understand than I thought it would but I still would love to have a shot at recreating these textures one day.
