Bug / Crash ArgumentNullException: Value cannot be null. Parameter name: key

[diegoaguirreh]

You have a MeshCollider in your scene, whose input mesh is null.

This is a known bug in 5.6 that will be fixed in upcominf updates. For now, the workaround is simply to ensure all MeshColliders in your scene have a proper reference to a mesh.

Hi! Okay, I had to start from 0 not really something good. I had to get a mesh and part by part asking a collider and an obi collider.

I found that the Mesh Collider with Obi Collider crash while testing. Thanks!
