I know how to paint alpha onto a displacement but I want to say I've seen multiple alpha's on a single blended displacement (grass, gravel). Am I wrong or is there a way to do that? In particular, these two textures. blendgroundtogravel005 blendgrasstoground005 I started out with the blend grass and painted some alpha grass on the displacement and then I changed the texture to blend gravel and painted gravel and the grass was still there, but only until I closed the map and reopened it and then the grass was gone and only the gravel was there. But I swear I think I saw a map with both blends on the same texture, maybe it was cp_boulder. Another thing I think is weird is when you paint your alpha, not grass, but the gravel, you think it looks right in Hammer and then when you go into the game it doesn't show up nearly as much as you saw it in the editor. Any reason for that? Thanks.
