Well... I figured it all out at some point and all I want to say that it's a crappy, buggy and nerv burning route to go.. The exporter is buggy and has really nasty pitfalls that you can and most likely will fall into (often). When I got my working Q3 player model done I decided that I will not never ever do it again To be honest I have already forgotten most of the stuff I learned doing this.

Anyhoo, the tags are just polygon triangles, whose normals should be pointing to a direction that makes sense. The pitfall in the tag tris is that the length of sides of tris cannot be equal or the exporter will crash... yes.... sounds odd but it is true... i ran into this just by experimenting and finally debugging the source code of the exporter... <- not fun :/

Anyhoo, you can find my Q3 player model in the link in my sig...
