A full compile log would be informative

qc script must include flex controllers defined inside

Would be better to see the differences.

> %eye_blink1 = eye_blink1
> %eye_blink2 = eye_blink2

You don't seem to have these flexes, but you have eye_blink. Replace those lines with:

%eye_blink = eye_blink

Also, your dmx should already include those flexes if you exported with 'Simple' flex controllers, so you don't need .vta file and vta-related stuff in qc.

Just leave default Binary 2 Model 1, this should be working.

Move the camera to the position of 1st p view and see through it as reference

Does exporting flex animations work now?

As it didn't before?

You need at least add some shape keys, then select your mesh with shapes on Source Exportables. Then it will appear.

Yeah, each material part has own uv map. They might not be the same.

Source doesn't support multiple UVs
