cggsoul - yep i totally agree with you. This piece was made for a game competition. That part of the model you are talking about, is infact a plane. So there really insnt much i can do. it would be very expensive to make that out of geometry. So for things like that i choose to do that with alphas. Which at work, i would problably totally obmit since they will tax the engine.
