no, i don't need rotating textures. it should work by deforming a polygon band into a disc and then simply scroll the texture in u direction. but probably i will try to use bones first...
i don't think it's a very realistic city.

but now i understand a bit better what you mean. my style isn't as cartoonish as the style of some other tracks but that's quite impossible to fix in this state. it also will be hard or rather impossible to achieve a consistent style for stk with so many different artists who only work on it for fun. i think it's a lot more important that the tracks are consistant within themselves.
but i have some ideas for additions now that won't be much work to add.
edit:
one more question... is it supported to animate the helicopter along a curve in blender? or do i have to use many location/rotation keyframes?
