Hi. Does anyone know where I can get a plug-in for Blender that allows exporting to Milkshape3D format? I have already looked, but I couldn't find it :( Thanks.

Well I make my models and texture them in Blender, then export to .obj (Wavefront), and import that into MS3D. It works with the model and texture data, but I'm not sure it would work with animation if you are also doing that in Blender.

Thanks for the suggestion, but I can't use Milkshape 3D at the moment, my trial period has run out. I am planning on buying it some time but in the meantime, I'm going to use Blender. I've only written an MS3D model loader, so that's why I need MS3D model format.

I doubt this is fully functional but maybe you can modify it:

The blender artists forum is good for lots of blender scripts.
