I think I’ve narrowed it down to specifically running the blast extension, current version is 0.7.2 kit_100.3. More specifically when I fracture an object with blast and try to play it back to demonstrate the physics.
My process is:
Open Omni Create → create physics scene → create physics ground plane → create material, omniPBR ( applied to ground plane → create mesh (any) → set mesh kind to component → with model (T) mode right click mesh an apply physics rigid body preset → from here I usually play the scene back with no issue to test that the object falls / hits the ground plane.
Interestingly trying this now, the cylinder I made fell slightly, stopped, and now omni create is locked up not responding with the windows spinning wheel as my cursor. However it hasnt crashed to generate a crash log in about 5 minutes, just locked in not responding. Force closing from this stage does not generate a crash log so I will continue up to the point in my process which generates the crash log.
Next I would open the extensions window to load omni.blast → switch to prim mode → select the mesh (cylinder in this case) → fracture object (from blast menu) → debug blast set to 2 or 3 to see the fragments / tweak fragments → play scene. The crash is very similar to what I described above but the program usually closes itself within a few seconds of locking. Object falls slightly then stops, I was able to get it to work and fragment / playback once when I initially opened it, however stopping and playing it again caused it to crash.
It shouldnt be a hardware limitation, am running rtx 3090 and ryzen 5800x cpu with 32gb ram aswell.
