Ok, it took me the longest time to figure out how games like halo, tribes, etc add extra detail to their maps. examples are trails, roads, and anything else that could''t go on a tiling grass texture or whatever.. I am trying to figure out how to go about sticking a texture on only a small area of terrain. I''m drawing terrain using ROAM.. Should I draw all the terrain first, and then the decal? Or draw the decal as I get to the polygons it covers? Someone help! :D thx ahead...
