i use worldpainter a lot for the major stuff for example, this quick map was made with just that. however i have custom brushes and othe techniques and things i have developed to make them better. if i am doing a really good map, like some of the one i have been working on, i will do the worldpainter, and then go in gane and use a combination of worldedit and voxelsniper to do touch stuff up and also do things like arches. hope this helps

would there be interest in worldpainter tutorials/voxel/worldedit and terraforming?
