It isn't a shame to own legal software it's just, 9 times out of 10, people who have problems with their 6.2 Pro software are not legal owners (more like 98 out of 100).
I would totally recommend update your engine to 6.31. It's free, it's quick, and there are a *lot* of fixes that will make your experience much nicer.
So i updated my GS but still have the same Problem! 50% transparency! I think it is something little i did wrong. Somthing with the alpha map probebly. Why do i need an alpha map? An Alphamap is usually used to make somthing transparent, right! BUT the tutorial says i should make a top texture with an alpha channle and an Normal map Texture as bottom map! In 3ds max i need a texture and a normal map, thats all. So why do i need the Alpha channel in the top map for GS???
i do not know wherefor the shader uses the alphamap in entSkin1 without having seen one line of your code, but normally it controls the specular value (spec map). if so, just as a test, try not to use an alpha channel, then the model should appear solid but totally glossy. if even this does not work, we really need the fx file/c-script code to help you.
