@JamesG That sounds like it would help quite a bit! I had seen the eDISABLE_CLEAN_MESH before and had thought about trying to enable that since I can output a clean mesh with my mesh generator from the voxels. So that would be amazing to get access to those. I’m c Right now I’m spending up to 8ms per frame baking collision, so I had been looking into moving baking completely off the game thread, and I’ve seen from the Nvidia documentation where it appears to be safe to move it to a separate thread, but I know that will depend also on what’s within UE4 that’s run at the same time, which I haven’t had time to look into yet. Here soon I’m probably going to investigate that myself unless you know of anything that will preclude it. Thanks James for looking into this!
