read access violation after contact callback

[AgentCodeBanks]

I simulate a conveyor belt in PhysX by applying a velocity to each object that has a collision with the conveyor belt. If I now convexly decompose the transported objects (short U-profiles) with the V-HACD v4.0 (https://github.com/kmammou/v-hacd) with relatively high resolution, my program crashes because I get a read access violation exeption when calling the method "PxU32 pairFlags = si->getPairFlags()" in the ScScene.cpp file, line 5465. This only occurs when I have the GPU pipeline enabled.

I suspect that the GPU is limited to a certain number of objects and the V-HACD creates too many small convex meshes.

Does anyone know how I can prevent this without changing the resolution of the V-HACD?

Hello
It's hard to tell from this description what's going on there. It would help if you could provide a repro sample (as a compilable snippet).
Thanks

Hello,
I have attached the mesh as a .dat file and a snippet on how we load the file and add it to the PhysX.

Hello. Thanks for your data, but to debug the crash I need a compilable sample that actually crashes when run, so I could run it in debug and see what's happening.
