Everything has worked fine until one section of my terrain has the world grid texture. I can`t paint on it or anything and seems as if the section has not compiled. Painting the terrain caused this,although it usually complies.Not this time. Help!
Found a very effective fix. If you go into terrain management, select the area/quad of terrain not compiling, and then delete it. Do this by selecting the delete option as opposed to the selection. After deleting problem area add terrain back to the exact spot. If you could not paint on terrain before, you will be able to after this.
