I've read ALL those threads. The DDS converter tool was made for NWN and does not work properly for TSL. I've tried it -- the texture ends up with a lot of ugly artifacts.
I never mentioned bump maps in my post, just DDS support. I think bump maps are supported, but, I think you and others may have your facts wrong about how to do that -- I think it works with a greyscale height map not a pink/purple normal-map.
Your comments are misleading and somewhat self-aggrandizing not to mention patronizing -- you can simply add a link to the post thread, you don't need to use the "Let me Google that for you" method. You also DO NOT bother to post up how to do any of this if it is possible. You simply suggest and link to stuff. I'm sorry, that is not concrete proof that it works.
I suggest that you grow up or no one is going to help you with your mod development .
