The UV map is the problem. What the render to texture tool does is write the lighting information to the texture map. If more than one face is sharing the same area of the texture, the lighting will get overwritten.

You need a "unique atlas"... all that means is that each part of the map is used by one and only one face. You can create one yourself with the TCE built into AC3D, or there are some tools that will make one for you. There's a texture tool called Ultimate Unwrap 3D that will make one automatically. There's also a freebie command-line tool from Microsoft called UVAtlas that will do it. It used to come with the DirectX SDK, dunno if you can download it separately.
