I want to make the forrest in WB actually look like forrests, by adding alot more trees. (Like 1257ad mod).
But it seems it has nothing to do with sceneOBJ folder?
No, the sceneObj. folder contains scenes like villages, castles, towns etc.
What you want to do is somehow edit how trees spawn on a randomly generated battlefield.
Or you could make a forest scene like a unique battlefield, but then it would be the same forest battlefield each time.
Anyway, I don't know how to do it either. But search around or wait for a smart person to reply here
