PhysX Mesh Shape

The PhysX Mesh Shape component provides the geometry of the collision area. You typically use it with a PhysX Collider component and a PhysX Rigid Body Physics component. The collision geometry of a PhysX Mesh Shape component is an invisible mesh defined by a .pxmesh file. You create a .pxmesh file from an FBX file. You do not need to add a PhysX Mesh Shape component if you use one of the following supported Shape components: box, capsule, or sphere. The cylinder, compound shape, and polygon prism shapes are currently not supported.
