This: http://opengameart.org/content/ground-p ... xture-pack (nice diffuse textures, but no normal or spec maps)
reminded me to look for a nice open-source & cross-platform Crazy-bump alternative again, for a convenient way to create normal and specularity maps out of a photo texture.
Now there is the still working normal-map plugin for GIMP:
http://code.google.com/p/gimp-normalmap/
Which is not bad by itself, however the result is only a normal-map and it doesn't have any advanced picture enhancing algorithms like crazy bump.
Now a bit for google searching found me this:
http://irrlicht.sourceforge.net/forum/v ... 0&start=30
http://code.google.com/p/insanebump/
http://irrlichtirc.g0dsoft.com/omaremad/
Which is sadly terribly outdated and has not been further developed since 2009 or so, however the results it seems to create look very nice. See this PDF for example:
http://irrlichtirc.g0dsoft.com/omaremad/insane.pdf
The source-code for this python GIMP plugin is available under the GPLv3, so I was wondering if there is maybe someone around here that could get it running under GIMP 2.8 and make a nice new release of it?
Thx!
Edit: Here are some instructions to maybe get it running on gimp2.8: http://www.gimpchat.com/viewtopic.php?f=15&t=467
