For small crowd I guess it's ok, but I always think about some more extreme cases For example I have a scene with 5000 agents

Do you really need though the VDB sim to collide with all 5000 agents? In this situation, I would only have the VDB sim affect/collide only the absolutely critical agents for the shot and let the VDB sim pass through(not collide) the other agents assuming they are background or far away enough from the camera. Also if your agents are high poly, then of course that will greatly affect the collision sim calculation. You might consider having the VDB sim only affect low poly proxy agents.

I got this to work quite easily using the Static Object in the shelf menu and selecting my crowdsource. It set up all the rest for me, worked like a charm.

I have a very basic crowd sim here with some low poly agents and I would like to have a smoke volume collide/interact with the crowd sim but I am having some problems doing so. At what level can I achieve this? At the crowdsource level? Agent level?

Has anyone had any luck at doing this?

Edit: My agents are FBX files, if that helps.
