Eh, I'm not getting such good results.
I got the muulti-texture, and importing all the textures to the shader, that was the easy part.
I'm having trouble getting the normals to react to light correctly. The dot product of the normals gives me results, but when moving the sun, it's as if the sun never moved. they stay the same, but the lighting of the face adjusts.
Not sure why this is, I'm gonna go do more testing...
