So now now there is one more functional free lightmap generator available in this world, I just released
irrEdit 0.4. I wrote
a short tutorial on light mapping with irrEdit, would be nice if you could tell me if it is helpful or not. I hope it's now again a bit easier to create free/open souce/indie games and realtime 3d scenes with that tool.
If you want to load those lightmapped scenes in Irrlicht 1.1, you might need to apply a patch included in the irrEdit download, or simply use
the latest version from the SVN. In addition, a lot more has happened, but
I wrote most of it down here.
