might be the edge detection that youre seeing on the trees. I really dont like those trees and Im going to most likely redo them when I get around to it. We just needed something fast. yes, the next step for the grass is to make them planes instead of billboards. thanks guys
Random rotation of grass, otherwise it just looks odd. Even worse... If you are going to use alpha tested surfaces don't for the love of god use a black background on the texture. Match it up to the pixel. Otherwise, you will have ugly looking shit like those trees there.
