I got it finally and I will start to read the tutorials. But I was kinda excited and started first:

The WOW model exported comes with 3 textures files, .obj and .mtl.
3DS can't open the .obj, but can import it. What I do with the textures and the .mtl?

If anyone has some experience with it, please share a few secrets, they will be well followed. Of course I will eat the tutorials but I am curious how all this will happen. I saw we can modify angles of body parts, which could not be modified in model viewer. It rocks!
