What "does not work"?

An extra bone is added to carry unweighted vertices. Without it your animation would look different once compiled.

It will only report syntax errors during the initial parse. Data errors aren't covered and I'm not sure that it's worth me spending the considerable amount of time needed to report them properly.

Just pushed a change to Git, give it a go[github.com].

I probably never added that to the datamodel parser. I can have a go at it over the weekend.

I've submitted a bug.[developer.blender.org]

Yes, it's one SMD or DMX file. Why don't you just try it and see?

Multiple actions for one Armature is fully supported but the UI for it is very awkward. I added a selection widget to make switching easier to Scene Properties > Source Engine Exportables.

Can you take a picture of your Scene Properties tab? The addon panels should be at the bottom.

Turning them all into 1 group would then force me to animate the model by vertexes, right?

No. If someone told you that, they are wrong. You can continue to animate bones after grouping the meshes.

The solution you've come up with is an overcomplicated way to achieve the same effect as grouping.

The tools allow you to specify a path to a DMX as your flex controller source. Not sure if you can extract them to a text file though.
