Features

What it does import:

• meshes
• materials
• textures
• uv mapping
• bones
• bone weights

What it does not import:

• animations: I did some experiments on this as well, but the necessary effort wasn't justified in my case.

Limitations

• Blender 2.7x
• I think I did not implement the whole B3d spec, but only the subset I needed for my files. If your files don't convert correctly, feel free to raise an issue.

How to use it

• Start Blender 2.7x
• Delete your Scene [optional]
• Paste the script from import.py into the Blender editor
• Replace "!!!!!PATH_TO_B3D_FILE!!!!!" in line 8 with the path of your B3d file
• Hit the "Run Script" button

Why creating this when there is Assimp ?

Assimmp did neither convert import bones nor bone weights correctly. I chose to do this In python as I felt it to be easier thant getting started with c++ and the assimp api.
