just_bob_2nd Posted April 28, 2019 Share Posted April 28, 2019 Hello, I've got cached rbd geo of a helicopter crash and I'm looking for ways to collide them into a pool of vellum grains, creating the ground debris effect. I'm looking for suggestions around how to import my helicopter pieces geo into the vellum sim. I also don't want the helicopter pieces to be deformed by vellum. Is vellum object the correct way to approach this? Quote Link to comment Share on other sites More sharing options...
jamesr Posted May 14, 2019 Share Posted May 14, 2019 If you just want normal collisions, you can use the Static Object DOP, tick on "Use Deforming" and "Re-evaluate from SOPs to Interpolate Geometry" and point it to your helicopter collision mesh. If you don't need super precise collisions, you'll want to polyreduce or make a shell around your geo to make your sim a bit quicker. If you're new to houdini, I'd recommend using the "Deforming Object" tool on the Collisions shelf tab. Quote Link to comment Share on other sites More sharing options...
