So normally in SDSME to start editing a map file, I'll locate it first by going to Matrix Editor -> Map Files, then double click on the area I want to edit. Then it'll open it up in the Map Editor, but it'll either default to No Texture in 1.8.1b or default to Texture 15 in 1.8.1 and 1.8.0 in every single map. Is it supposed to function this way and I might just be missing something or is there another way I can find out the correct texture for a map?
