Hello,

I have a fluid sim with reseeding and narrow band turned off. I want to do some secondary stuff based on speed and vorticity of the particles in the sim. I filter the point according to thresholds on speed and velocity and remove all the other particles. What I notice is that I have a load of randomly generated pockets of speed and vorticity in the fluid. What is this caused by? I thought it might be reseeding causing bursts where new particles are added but it's off so the behaviour is unexpected.

This is just a quick question: Does Renderman 26 (RIS) in Solaris support volume light (the light from the emission of the volume casting onto the scene around it)? I know it doesn't support mesh lights but I thought volume light might work. Doesn't seem to be though.

Ah. After the copy. Of course, because the orientation wouldn't be updated. Thanks Tomas!
