I'm in the process of creating diagonals for some curtains and my shadows aren't showing up. I assumed I was just linking something wrong even though everything else works fine but I noticed that none of my Maxis curtains have shadows on a diagonal wall either even though the few diagonal curtains I've cloned had the shadow mesh and shape info. in the package.

Is it even possible to have shadows on diagonal curtains? If it is possible, since the Maxis shadows don't work, does anyone know of any CC curtains with diagonal shadows that I can take a look at?
