How Do I Delete A Reskin?

A couple weeks ago I downloaded this reskin for the citizens.

It was good for a while, but eventually I decided to delete it. So, I went to my gmod folder like I usually do and sent the file to my recycling bin. But when I loaded up garry’s mod, the citizens still have the skins. I’ve tried going to my recycle bin and completely purging the file from my computer, but the skin is still active. Anyone know how to fix it?

delete the vtx and vtf files.
Did you apply the skins to hl2 as well? Garry’s Mod mounts the files from other source games so your going to have to delete them from all your source games if you want to get rid of them.
