Yeah, that doesn't surprise me. I think I have only 1 map that isn't based on a completely water-type map, and it's one that I'm going to re-create later once my worldmap is done and I've filled in enough places in that area to allow the PC to go there. As for lighting schemes appearing map default when you know another scheme is being used, this has to do with a file that I don't think is mentioned in the worlded manual or DarkUnderlord's Amtut. Under the folder for each map, there should be 2 text files. One is startloc.txt, which is set by right clicking in worlded and selecting "set as start location." (I think that's just for multiplayer. It's been a few months, but I think worlded 1074 uses "set as start location" to set both this text file and the entry in maplist.mes.) The second text file is mapinfo.txt. take a look at mapinfo.txt for Ashbury Haunted Castle (Arcanum/modules/arcanum/maps/ashbury haunted castle/mapinfo.txt): LightScheme:2 SoundScheme:13,39 Map default isn't a lighting scheme: it just refers to whatever values are set in mapinfo.txt for that map. When a map is created, it doesn't have a mapinfo.txt file, so the assumed lighting scheme is 1 (Lighting Default, i.e. the main Arcanum map lighting scheme). If you don't want to set your lighting schemes (or sound schemes) manually, you can create this file yourself. What you might want to do is just copy the one from "maps/Shrouded Hills-Panarii Temple Lev 1" and drop it in your other SH maps, and it'll play the sound scheme from there too.
