Lines? You mean the black grid (ctrl+t)? I could make it white; but if I have to make it thinner it would mean that each different terrain would have 1MB bigger textures.Check with TB as to whether or not lakes/rives can be added to the core, but if he says its ok, PLS ONLY use the default lines and not the added ones you have here in the modmod, thx. . . SO
Rivers and flood plains doesn't have any lines though; but do you want the new flood plains into core too?
