I made a python md3 importer for blender
you can get it from
https://tremx.svn.sourceforge.net/svnroot/tremx/trunk/blender/more or less the same as xreal one but better importing
(and maybe some little change on the exporter. dont remember if I did the change before of after)
(-formerly known as vcxzet )
edit:
optimized alot with the help of ideasman
probably, this will be included in the next blender release
you need python 2.5 for blender 2.44 ( they removed pythonXX.zip
)
you dont need anything for blender 2.43
