I've heard that overlaying blocks/objects can be very bad for maps and optimization of maps. The problem is the complexity of maps and avoiding overlaying while still having details with them. Is there a tool of some sort that works like a mass clipping tool that removes the parts that overlay other blocks/objects in the map? I'd really, really like to find out that I don't need to manually edit my maps, especially because I'm new to mapmaking and I don't know anything about what I'm doing. Also, is there a tool that makes all entities and blocks fixed to the grid (an aligner, of sorts?) Is there any other easy optimizing tips I can use?
