Hi Ray, that is something that I would like to add in the future. It is actually listed on the wishlist a few times already (http://moi3d.com/wiki/Wishlist).

I'm not exactly sure on a timeline for it, but yeah probably a v3 thing, I would think it would go along well with a more full rendering material property kind of setup.

Probably the focus in v2 will be more on simple colors to start with.
