I just did a test with importing models from blender, but I got this error:
Blender could not convert the .blend file to FBX file.
You need to use Blender 2.45 or higher for direct Blender import to work.
I am using “Blender 2.45 or highter”, I am actually using blender 2.55
You need either Blender 2.49 for auto-import or (until the automatic importer is done - which will be after Blender’s scripting functions are solid) do a manual FBX export from Blender 2.5x to your assets Folder.
