Can't find the Garry's Mod 3D Anaglyph setting anymore!

I remember gmod had a setting to turn on 3D anaglyph, you could even change the color settings from cyan/red to other color combinations to fit your glasses!

But, I can’t find it in the menus anymore. Did it get removed in one of the updates? It’s driving me crazy to think that it may have never existed at all! 0_0

I can’t say I remember this effect other than the stereoscopy pp effect. Sorry bud. It might have been removed
