For those struggling with getting these to work in Blender:
I recently had some relatively good luck with other .fbx and .iqm models by opening them in a tool called Noesis (
http://www.richwhitehouse.com/index.php ... ojects.php ; runs fine with WINE under Linux) and exporting that to Collada .dae. This then imports often fine in Blender and you can even get the correct bone chains if you play around with the import settings a bit.
Didn't try this with the Ryzom assets so far though.
Edit: I just tried it now, and it seems the above trick does not work (noesis struggles with .iqe it seems), however the .iqe imports quite fine into Blender3D 2.76b to my surprise. I guess that is because the Blender importer was written by the same person who converted the Ryzom assets into .iqe
The only problem is that the animations are in multiple files, but since .iqe is a ascii format it seems possible to edit them together with a text editor:
