Windows are part of the ship texture... I just wish it didn't shift everything. The normal map looks great but when you add the height mapping eh. Too bad displacement will never be supported or very efficent.
Dude, I've told you already a couple of times now: Don't apply a heightmap to flat textures. This is a flat texture.
You say it looks great with normal mapping - well leave it at that! You don't apply glowmaps to asteroids, so don't apply heightmaps to flat surfaces!
