Level Design [Help] How do I "paint" additional textures onto my existing Terrain?

[Christina]

Hello everyone, first time posting here. I've been a long-time Killing Floor fan and I'm working on my first custom map; having difficulties with terrain. I seem to have the basics down of how to create the terrain and "sculpt" it, hills and whatnot - but I cannot figure out how to add other textures on top of the base texture. I'm trying to make a large yard with things like dirt paths, maybe some plant texture variations, etc. Google searching provided me with one youtube video that showed it was done using a "color" tool in the terrain editor, but that was in the Postal 2 version of UnrealEd - and Killing Floor's version of the sdk doesn't seem to have this option for me...
