Thanks lolek, but you have to know that I already use the colormap
It works great, but it would be easier if there would be a grass script that doesn't need a bmp where I have to define first where I want to have grass (because I want it just everywhere where is grass texture). But I don't want to complain - even if it takes me 15 minutes to get it working, your colormap is great. I don't want to imagine how long I'd have needed if I'd have placed all the 1500+ grass models in my level per hand... so, thank you for the colormap ^.^
