So, I'm new to mapping, and when I tried to make a different terrain style in radiant (Simple Curves, Simple Terrain, Primitives, whatever) the texture just don't apply to the terrain/brush, I tryed everything, maybe I messed up some stuff, but sill only shows the outlines of the curves, instead of the outlines WITH THE TEXTURES. Could someone give me a tip of what's going on??? I'm following youtube tutorials by the way.
