Open it with notepad.

You'll probably have to dig through some folders. Inside the decompiled there should be a qc file. Look for the $cdmaterials line. That's gonna have the directories where the materials are.

If it says "models/player/medic", then go into "[modfolder]/materials/models/medic".

You don't get the vtf file from decompiling a model. You get the mesh and associated armature files.

Vtfs are located in [modfolder]/materials.

Then you edited the qc, different than what I instructed you to, or have an older version of the qc. Line 1 on the one I have over here doesn't have a bracket.

Go all the way to the bottom of the qc, and delete that bracket. After that, I got this error:

ERROR: cannot find bone ValveBiped.Bip01_L_Toe0 for bbox

Sounds like you need to add this bone to the bbox. I gotta go though, so I can't look at that error right now.

Preferably all of them.

Can you upload your compile files somewhere? I really think there's something missing here, and would like to see the files myself. Google drive or dropbox works.

This guide helped me:

If you already have it all ported to source, weighted well, and have all the compiling files together, you can probably skip to the compiling chapters.

Your version of crowbar shouldn't affect the (I assume) reference files l4d2 gives you.

That's waaaaaaay out of date. You should be able to follow with the new version.
