Coz_y_not Posted March 20 Share Posted March 20 Do I need to rasterise velocity into collisionvel field at the collider level before simulating, or is it ok to not rasterise it, and let the solver take the velocity from the points? the collision source sop doesn't offer this option while the vdb from polygon does. What is the difference if any between rasterising it before and not? is it reducing sim time? Quote Link to comment Share on other sites More sharing options...
haggi Posted March 21 Share Posted March 21 It depends which solver you use. If you use the sop level solver, the velocity should be inside the collision vdb as much as I know. If you use the dop workflow, there is no need to rasterisze velocity since the collision velocity is taken from the incoming points. Quote Link to comment Share on other sites More sharing options...
