I saw a post some time ago that did an effect like this using the same or similar method, can find it here.
It’s a cool effect, something I wish Roblox would add as a child instance or property of Camera that we could toggle and edit. However with this method, using glass, we can’t see terrain water, particles, smoke, etc. when looking through said glass.
Makes me wonder if there’s some way to produce this effect using ViewportFrames.
Yeah, That’d be cool to see post processing effect’s build into roblox.
Some cool effects for that would be stuff like FishEye, Warping, VHS & Chromatic Abboration.
I hope this actually becomes a thing (Just like build in optimization).
