I've been trying to crack this problem for a while now and I'd like to know if there's a tutorial or two out there that can help me with this. I know how to do shadow mapping with a single light, and I know how to implement multiple lights. What I can't seem to do is put them together, despite my many attempts.
So yeah, does anyone know of any XNA tutorials that can baby-step me through this?
