This submission contains smoothened L4D survivors fully standalone. All textures and animations included.

This acts as a mod! 
It replaces all uses of these players that you had used in every project you saved.
Only downside is bills cigarette, which will be moved away, so you will need to manually move it to his mouth.

You must change the loadorder of your "Workshop" folder in your gameinfo.txt (or via SDK) to have this actually replace your previously used files! 
The workshop folder must be before the "left4dead2" folders. If you do not change the loadorder, the "left4dead2" files can overwrite and nullify this addon.


Other things this addon does:
Fixes vomit overlay and also adds it to hair textures.
Makes hair two sided, disabling "NoCull" for better lighting
Makes Bills Cigarette be posable by a bone, but also still works with face flexes.
