Actually it support import of mesh vertices and triangles (position, normal, tangents , bitangents, uv texcoords (only the first layer in case of multiple layers), and vertex colors (yes !).
The import of texture from blender files is not supported but if your texture file is is the same folder and have the same name the importer will automatically make the link (for diffuse and/or normal maps) !
For the moment there is no support of material variables (no MTL).
No skeleton / no animations
Cameras and lights are imported but not referenced.
I highly recommend to import using the new option "Import as reference".
