Original post by Thanhda BTW any good MD5 loaders? and exporters?

I am writting one, but is far from done, it loads and writes the .md5model files, but not .md5anim yet, there is a third file for cameras, but I have not even looked at those.

Does anyone know if the same situation applies to MD3 files ? IE you can create them however you like (blender with MD3 export plugin) and use them in a commercial product without penalty ?

Yes, the same applies, the same goes for .MAP and .BSP in case you're wondering.
