Is it possible to ray cast a none physics mesh? E.g. a complex Mesh Renderer, with a mesh filter on it.
I’m trying to create a work around, as updating mesh collider looks like it will be way to slow.
Updating a Mesh collider is slow, because PhysX will create optimized data structures to be able to efficiently calculate collisions against the mesh. The only other option you’d have would be to manually calculate your raycasts in a script code checking Mesh.triangles and Mesh.vertices. This will be much slower then PhysX.Raycast, but may be more efficient if you need to update the Mesh often and only do occasional ray casts, then it may turn out to be the faster solution.
