Hand painting textures, modifying , adjusting 3D tiles = long hours ....
So much problems with edge extrusion, than recalculate normals outside ? unwrap on some faces, but the painting don't work, even directly on texture ? ? vertex problems ?
---------- More complex graphics = lot more time spend. So my rule now is : KEEP GRAPHICS SIMPLE (Like Dungeon Dities) ! I bet on gameplay, fun, cool world : places/NPC , puzzles, dungeons and fun than graphics.
