point into correct qc then

You will also get ERROR: z:\tmp\letspretendididntseeit\qc.qc(73): - can't find eyeball texture "eyeball_r" on model further. Solution:

Leave only one $model. AFAIK only one allowed.
Group various objects, including eyeballs. Source Exporter will export them united as one dmx.

I'd better not see it Line 5:
$model "Body" "Pao Pao.dmx"
Remove it

A blender project uploaded would be nice to certainly investigate why it happens.

Re-generate new controller if you did before.

Import reference smds instead

Misfire! lähetti viestin:

Can you explain further? Why is a modifier needed where none currently exist in my project and 2.71 doesn't seem to require one to work correctly?

Because that's how it does work in Source.
If it's not ragdoll, assign all vertices of collision mesh to Base bone vertex group. Or parent collision object to base bone. In both cases apply transforms of that collision mesh. Re-export.

Collision mesh should have Armature modifier added as well

That's what I refered as reference pose. One with un-applied transforms

Multiple $model statements are not allowed, use $body instead

And you mentioned (one) exported SMD while there are multiple smds in qc...
