Problem encounted in generating collision shape

[Dingry]

Hello, thanks for your exciting work! When attempting to generate a collision shape, I've run into an error on occasion. Could you possibly provide some assistance with this?

I believe the issue may stem from my mesh being cut from the complete object. Could you kindly provide some guidance on how to resolve this problem? Thank you!

I think the error happens in manifold check, you can set preprocess mode as "on" to skip the check (force remesh).

I will find the bugs later.

Thanks so much for your advice. The issue was resolved by re-meshing via trimesh.smoothing.filter_humphrey. It appears that peculiar structures within my mesh caused this problem.
