Hello
I'd like to suggest more complex textures. Why not make some layers that will allow to put some glow and highlights to the texture, also it would be nice if we could use normal/bump mapping for better grunges and damage effects. It will improve aesthetic feelings about graphic side of game if all textures have had normal/bump mapping layers. Main disadvantage of it will be of course need to use less known/popular file formats or using few files at once if stick to JPG's, but it is worth price to pay. Maybe there are some users that would like to drive tron-like car

It would be cool (as the multiple times this has been already suggested indicates), but actually LFS has serious limitations with transparent textures. It have problems showing fences throught smoke and such things, I guess introducing more layer would only make the problem much worse.
