So this is more complicated than I thought. I'm wanting to do 2 things here:
1) Tag only particles that are within the volume of the bucket
2) Assign them a tag that can be used in post to mask them, like Object ID
The first part though is proving difficult. As the volume moves through the mass of particles it should test whether or not a particle is inside or outside the volume. Here is my attempt at this, but it does not seem to work. As far as I can tell, VRay is picking up the Instance ID operator assignment in it's Render ID render element, but there's no documentation anywhere to verify this is right.
Anyone have any suggestions?
