Thanks man.
This makes getting models from Blender into Quake super easy, at least compared to what I did before. The horror! Never going back. I'm currently exporting to md2 in Blender, and then running your glorious little program. The only thing that would make it even better would be support for .obj or similar so conversion to md2 / md3 becomes unnecessary.
Is there any progress with the md2 or md3 export function? Because then I could edit original Quake models in Blender and quickly export them back O_o

Also thanks for keeping this crossplatform.
