Then you should give us your model (both .blend and .mdl files) for testing

Last problem is unrelated to exported itself. Leadwerks model viewer under Linux has this problem on most animated models and Josh knows about it.

It seems like you have some non-latin symbols in material names. For example: "Grünerknopf". Current leadwerks file format is not supporting it.

No way for Kickstarter backers to get Ubuntu Sofware Center key for free? Just want to leave a good feedback :-)

Why not to do Blender exporter development community driven? Split the work into set of small tasks. Make github repo and we will do rest of the things. Give a reasonable and fun rewards to most active participants and everyone will be happy. Just writen a boilerplate code for plugin if it helps somehow. For now plugin is installable and has some UI, but do nothing.
