GShaders 

On this boosty, I post unreleased shaders that weren't published in workshop, as well as older versions. Both work-in-progress and fully completed shaders are available here. You can upload shaders from here to your server content if you want to use them on your Gmod server. I maintain the shaders from here just like I do for the workshop—posting updates and fixing bugs.

Once a month, I'll hold a vote to create a new shader of your choice. Votes will be cast from the feed. I'll then release it here. It could be stylistic shaders, overlays, or some kind of graphical shader.
