ela1995 Posted March 3, 2020 Share Posted March 3, 2020 Hi, Recently I have trouble when using the Volume Source as a Collision for my pyro scene. I cache out the object in VDB, then loaded back into a new scene. Why my smoke still don't collide with the collision? Quote Link to comment Share on other sites More sharing options...
Diego A Grimaldi Posted March 4, 2020 Share Posted March 4, 2020 is the name on the field correct? Did you check the gradient of the volume? Quote Link to comment Share on other sites More sharing options...

I believe 'collision' and 'v' is the require field in order to create the collision using volumeSource. I'm sure the name on the field is correct, but what is the gradient of the volume?
