For those that use KOTORBlender, I forked seedhartha's repo to make a few tweaks in case anyone is interested. Fixes the texture search path for Windows users, adds a new separate search path for lightmap textures, and adds a menu to the UI with some show/hide functionality similar to KMax:
I'm open to other ideas if anyone has suggestions for further KMax-like additions. Although I'm no programmer, so I'm not going to be able to do anything too fancy.
Edit: I created a pull request to merge these additions, so you can now just download it directly from DS on the KBlender page in the Tools section.
