Alright, I'll take a look at it tomorrow since I don't have classes then.

Actually, none of what I have told you is guaranteed to work. I've been having some issues with it myself...

If it works, congratulations! If not, then I apologize in advance.

Disregard what I said, I have led you astray.

At the very end of your flexes list, you need to have these:

flexcontroller eyes range -45 45 eyes_updown
flexcontroller eyes range -45 45 eyes_rightleft

This will probably help you more than that forum post. If it still doesn't work, I could take a look at it if you like.

Something to note is that you're not actually supposed to have a bone for "viewtarget". Eyes are shader based in source, and an iris is generated over the actual "ball" of the eye. You need to make sure you have the following in your QC:

$attachment "forward" "ValveBiped.forward" 0 0 0 rotate 0 0 0

That is what controls eye movement in source, and that's what SFM will label as "viewtarget". Hope this helps!

I've actually been working on porting some models myself, although I am porting the parts necessary to create some of my favorite soldiers. I am almost done with one of the, I need to find time to finish flexes. I eventually plan on making flexes for all of the heads...but that is a long term project to say in the least (there's several heads for each gender and ethnicity). When I get the time to finish working on stuff, I'll be sure to post back here.

Add $opaque to the QC.

I'm going to try something Imperial Guard related. Pretty sure that's military.

It's probably the phong settings. I'd borrow settings from another model to get it to look right.
