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

List all needed bones in .qc using $definebone's. Those which aren't listed won't be included in compiled model.

You'll probably need to duplicate your old mesh and re-rig it on newer c_ skeleton. And re-animate it. The easiest way is to use constraints.

The Source Engine itself doesn't support bone scaling in animations. What exactly you're misunderstanding?

You might try using flex animation if you can figure it though...

So the problem is that vertex on the end is being still? Maybe you forgot to assign it to desired bone.

There is no anti-clipping mechanism for jiggles. You have to adjust jigglebones' angle limits to somehow avoid that.

Try exporting SMDs
