yeah, that helped! different level of spec... the guy who throws all together in the realtime app thought about to use 2 geometries (hair and head) to make use of 2 different shaders, but we dont quite know if we are going to be pleased with the result. both procedures haven´t been tested yet. we are still trying to evaluate in a imaginary way actually to anticipate problems we might run into. you think just a specific spec map will simulate hair nicely? I will try.

thx for your input. I´ll post updates if I am allowed to.
