art3mis Posted November 10, 2020 Share Posted November 10, 2020 Any pyro experts? I have a Smoke Trail sim I'm happy with but can't seem to get it to collide with my ground (extruded grid converted to vdb). Based on the attached can anyone suggest what might be wrong with my collision workflow? I'm simply merging the vdb ground plane into the 2nd input of my Pyro Solver.

bunker Posted November 11, 2020 Share Posted November 11, 2020 You need a VDBfromPolygon node instead of "convert" or use the collisionSource node if you use the Self tool / static object, you'll see how that should be setup. Quote Link to comment Share on other sites More sharing options...
