Meh, sorry about that



Nope, at the moment you just change a value in the shader. A lookupmap is a good idea though, as it's way more flexible. I'll change the shader accordingly.



It's vs/ps 2.0 at the moment. I think this can be changed to vs 1.0 and ps 1.4 as the shader isn't very complex. I just start all my shader in vs/ps 2.0 as they are more convenient to write this way.



Depends on the model/scenecomplexity. It's definately not a frameratekiller



Yes, this can be easily changed in the shader.
