Have you (or anyone) tested the script?
I have tested it out, yes. Unfortunately, I haven't gotten a working animation out of it yet, (but almost):
(I used the latest Directx SDK dxviewer.exe to view)
SAS: Loading effect 'Resource:#103'
Tangents and Binormals cannot be generated without a 2-element or greater texture coordinate at TEXCOORD0. Please use DXOps to UV-Atlas your mesh.
Binormals do not exist on mesh. Attempting to calculate.
Tangents do not exist on mesh. Attempting to calculate.
'' material 0 - No effect instance specified.
Reverting to the default effect.
I haven't been able to contact my blender artist friend yet, who made the animation. There's probably a few things that need to be altered in blender before exporting.
The guy that made the script claims it works with everything he threw at it, so it's worth a shot. I suggest whomever's interested to test it out and see. (read the blenderartists thread following the above link for more info)
