I hadn't made the connection, but now that you mention it, a lot of the props I have shadow problems with are imported meshes, too. Perhaps all of them. - I wonder if it has to do with the geometry being contained in the prop file, not an external "Geometries|*.OBJ" file? - Never thought about it til now, but is there a way to extract the geometry from one of these props so the prop file calls an external geometry? (Obviously there is, but I can't recall anything covering the procedure) Anyone?
