Well, you couldn't forget me, I did most of the animations of the clonk and Ringwaul reworked some of them. And yes, I am also not really active anymore. But some months ago I had reworked the animations script to enable exporting clonks with the new Blender version again. Then I had problems committing the patch. Could be due to the proper right missing, or that I used hg2git or how it was called to continue using mercurial. I should take a look at it.

EDIT: I have found the files. I didn't succeed in committing, therefore I post them here. Perhaps someone can commit these two files
I attached the script, but the blend file was too big for the attachment: http://www.renderclonks.de/files/ClonkOpenRevolution.blend
To use it, copy the script into your blender script folder. It is then listed in blender as a new exporter "Ogre Exporter Clonk", which works like the normal exporter, but has some special features used to export the clonk. It reads like our old exporter a Actions.txt to define which actions to export and which bones to use with which animation.
