PxTriangleMesh collision error

triangle mesh collide with triangle mesh

Hi,
As I tried to make two mesh shape collide with each others, I got error reported in the GPU dll:

PxgCudaSolverCore.cpp (1702) : internal error : GPU mComputeBodiesAverageVelocitiesFunction fail to launch kernel!!
PxgCudaSolverCore.cpp (1681) : internal error : GPU solveStaticBlock fail to launch kernel!!
PxgCudaUtils.h (75) : internal error : SynchronizeStreams cuEventRecord failed with error 700
PxgCudaUtils.h (81) : internal error : SynchronizeStreams cuStreamWaitEvent failed with error 700

As one of my actor are PxRigidDynamic I enable the sdf when cook my mesh shape, something like:

since GPU dll is not open sourced, and I have no idea how to debug this kind of issue as mesh vs mesh is a common case in our application, hope someone can help to give some advice here.
I also export the ovd file for this scene maybe it a bit helpful to reproduce the issue.

Hello, I had a look at the the ovd capture but I could not find something that is obviously incorrect. It might be worth to try a couple of things to see if it starts to work afterwards:

• Ensure that the sdf spacing leads to a reasonable sdf resolution. An estimate of the resolution will be boundingBoxDiagonal/sdfSpacing. I tested the scene in omniverse and it worked quite well with a target sdf resolution of 500. The options to sparsify (compress) are identical as in your scene.
• Maybe it is worth to try a kinematic rigid collider instead of a static collider. But a kinematic rigid would also require an sdf. But since both parts are identical, the sdf can be shared.

The file I used to experiment is attached. Maybe it helps to copy some settings.
