Hmm..that makes more sense now Gothix. If I have a hill with 3 different textures at different heights, I'll assume I just have to manipulate multiple brushes to get the fade effect. Because I never got the whole trisouping thing. I'll assume trisouping is making a brush into 4 triangles...or...what I do is just vertex edit and then I have 2 different triangular surfaces but one brush. I will assume this will still work. If not then I have to cut up the brushes where I want the terrain to blend.
My kung fu is also very weak
