Help Does Obi Disregard Convex Mesh Colliders?

[josemendez]

It's my understanding that a convex mesh collider is considered non-hollow and much more performant than a standard mesh collider, at least inside PhysX.
Obi does not seem to care about that however...

I know about and love Obi's SDF colliders, but no support for non-uniform scaling is a huge deal-breaker for our use-case.

Setup: All convex and primitive colliders!


Results: Yes this setup works perfectly with SDF collision!

All MeshColliders are considered concave in Obi. The reason for this is that Unity's API does not expose any representation of convex mesh collider: no plane list, no point/edges, nothing. All we can work with is the original mesh.
