Thanks again, Dark! I've downloaded and installed Blender 2.62, downloaded the io_export_md2.py.7z file, unpacked it into the scripts dir, I still cannot export anything. May I know what procedure are you using? BTW, I've tried again, if I make a group with all the brushes and export it to .obj via Radiant, then Blender can open it! Now I just need to understand how to transfer from blender to md2 and I will be set.
