 - Automatic generation of convex colliders matched perfectly to the shape of your mesh, the number of vertices to sample should be set to match the number set in the .phys file in order to ensure successful export.
-- Generate box and capsule colliders with either user specified sizing or sized automatically to match the selected mesh
-- Export edited collision bodies back to .phys ***currently requires a wolvenkit converted .phys.json file
