Importer plugin for Blender. Lights, geometry, materials, textures, UV mapping coordinates, multiple UVsets, vertex colors, vertex weights, bones and skeletal animation can be imported. See the plugin readme.txt file for more information.
Here’s a little more information about what we released:
We released a Python script to export Blender scene data to an intermediate format.
Lights, geometry, materials, textures, UV mapping coordinates, multiple UVsets, vertex colors,
vertex normals, vertex weights, bones and animation can be exported from Blender.
This intermediate format can then be read by our program, Ultimte Unwrap 3D.
The script was developed using Blender 2.66, so it may not load for older versions.
It supports armature-driven animation only.
We mainly wrote this for Blender users who are already users of Ultimate Unwrap 3D, but, anyone can use it if they want.
As for comparisons, it’s similar to FBX export, but since it’s optimized for Unwrap 3D, it’s much faster.
