How do you? I've looked everywhere for some type of "map creator/editor" and have found none that shows what you have done. Is there a map creator that allows you to see what you are doing?
If you mean a program for creating modules like the NWN Editor, no. We likely never will either, as we recieve no official support for modding these games.
We only have the capabilities currently in KotOR Tool, or by manually editing module files ourselves. And we cannot make new levels, only re-use existing ones. Sorry.
You may see only supported maps in Kotor Tool's map editor but they are large enought. In other things I agree with RedHawke. Little remodeling (wolakmeshs,layouts,other brrrs...) may help to remodel the existing are a little, anyway it is not new level.
