I need to import a mesh animation from Cinema4D into Blender.

I tried to do that using Collada.The Collada 1.3 importer doesn't seem to do anything, the Collada 1.4 importer seems to work, but the animation didn't get imported into Blender.

After reading this post, I tried modifying the animation nodes in the collada files, as explained in the post:

<library animation>
<animation>
<animation>
data
<animation>
<animation>
data
<animation>
<animation>
<library animation>

to this:

<library animation>
<animation>
data
<animation>
<animation>
data
<animation>
<library animation>

, but that doesn't work for me. I get an errors when the file is parsed.

Any hints on how to import a mesh animation from Cinema4D into Blender ?
