art3mis Posted October 21, 2019 Share Posted October 21, 2019 Trying to set up a simple VDB collision with rotating 'fan' geometry. My issue is I am missing point velocity in my VDBFromPolygons SOP. No point.v available under Surface Attributes. What is the simplest way to resolve this? collision_VDB_missingVelocity.hiplc Quote Link to comment Share on other sites More sharing options...
Skybar Posted October 21, 2019 Share Posted October 21, 2019 Its missing because you dont have the 'v' attribute on the incoming geometry. Quote Link to comment Share on other sites More sharing options...
