Question about the envo map
As far as I know the envoirment mapping is created by using the alpha channel of the *-shine map of a texture.
I now got the problem that this map seams to be completly ignored. No differance if its near white or near black I still get a strong reflection that makes the ship look like its made out of glass.

I am using TGA textures for testing and will later compress them into DDS format. So an alpha channel should be used and saved with the texture. What could I do wrong?

I guess that black means no reflection and white reflective.

I normaly check if the "save with alpha" is on.

Re: Question about the envo map
Do you have the 'Experimental' launcher flag 'Use specular alpha for env mapping' enabled?
