Can you teach me how to port from other games?
Well i can start by saying that you need 3ds max, otherwise it can be difficult to convert from most games
I suggest reading tutorials, but some programs are pretty easy.. For most games there is a big modding community, and they often have tools to export the models to a compatible format for 3ds max such as .3ds or a plugin to directly import the game's file
Are you using smoothing groups?
Whats that? I am smoothing the models if thats what you mean.. When import from GTA IV and export as smd, the models looses the smoothing, so i had to smooth them
