Help extracting animations from Left 4 Dead / Left 4 Dead 2?

I am attempting to extract the player model animations from Left 4 Dead and Left 4 Dead 2. I have successfully decompiled them using Crowbar but when I open them in blender every frame in the animation is just a T-Pose.

Yeah, you cannot directly decompile L4D anim files to SMD

But, you can get the animations by loading the model into Source Filmmaker, picking the animation you want, then exporting the animation in the scene as DMX, then it will be able to open in blender, then you can export to whatever you format you want, and make your edits in 3Ds Max or keep it blender without exporting, or whatever.
