VDB advection

Is always fun to play with vdb surface advection over time. But this time, I tried to advect also the rest position in order to get the colors moving along the surface. So I ended up with this kind of paint effect. Two rest attributes are being mixed over time.

This is a non-commercial version project file. The scene was rendered with Karma-XPU. You should cache the scene for better performance inside Solaris.

Shading done with MaterialX.

The first scene you see in the video was rendered in redshift using OSL color paint shader from Saul Espinosa's RS-OSLShaders.
