I don't have c4d, so I can't answer the first part. A for the second, if you want a single OBJ file but two seperate props to use it, you'll have to hack it a bit. in your prop file you'll want to have a figureResFile line like in a CR2, then use the same syntax a CR2 body part actor uses to refer to a specific group in a prop but instead of an actor block, use a prop block. Look at both a CR2 and a PP2 file and make a PP2 that works like a CR2 to get the geometry. (Don't try to write a PP2 from scratch, not many of us can do that B^)
