hello, i am having trouble figuring how to make concav physics shape in my mesh that actually work. For instance i have a floor with a hole for the stair, and i made a physics shape with that hole in mesh which i loaded into the physics properties in the mesh import dialog (it also shows as yellow seethrough structure then). But then the mesh behaves as if there is no hole in it when it is rezzed? I also tried changing physics properties to prim and convex, nothing seems to work. Any help out there please? Do i really need to break up everything into convex portions? :/ ty, Babs
