Currently we have terrain diffuse map generated by l3dt+lots of photoshop modifications. Usually borders between areas (snow vs sand vs forest) were manually shifted little bit to more respekt terrain shape.

Now I need to put these modifications back to l3dt, to generate proper alfa maps (doing it manually in game editor is possible but lots of work). Would be possible to somehow generate attributes map in 3rd party editor like photoshop (I would use diffuse map as template and generate atrributes map from it)? Or is there any other way? Thanks!
