Get halfway through a model and find it's an unworkable mess? Can't add edge loops where you need them? Can't subdivide a mesh properly? If any of this sounds familiar check this course out.
I know most people make there models in polys and then make them into the tri's for a game engine. but is it possible to use nurbs or even subd's characters and have them used in a game engine. And if you can use them how do you tell the poly count on a subd surface since i think it just tells the number of polys.
AFAIK, there are no game engines out there that directly support NURBS or sub-d's. Everything must be converted to polys before export. Simply put, NURBS and sub-d's are not very efficient for real-time applications.
