That looks like fantastic piece of software. If you look into the support section, it does say that it is supported by C2 so that is definitely good news.
Haha to be honest, I had no idea C2 was able to support normal maps. Needless to say, I immediately open C2 to have a look, and I think it is in the effect section, at the bottom, there is the normal mapping option. It works, but wondering what the performance dropoff will be like vs the number of normal mapping objects we use.
