hi!! ive been working on recreating macOS inside Roblox that is actually high quality, including having working liquid glass!
i didnt want the glass to just be transparency, gradients, or a fake outline like how others do it. i wanted the wallpaper behind it to genuinely bend and refract through the controls like it does in macOS
In terms of lag, that issue is likely not even your fault. Roblox limits updates to EditableImages to 1 per frame, queing the other updates. It’s really just an unfortunate restriction that was made when EditableImages were in beta and a lot less performant than they are now.
If you want it to work outside of UI, you could do some funky stuff using raycasting to get the “color” of parts, though notably this wouldn’t work amazingly with textured meshes or materials.
not yet, i managed to make it work over other ui’s, but it is very laggy and thats the thing im trying to fix before selling it or making it open sourced cuz im lowkey giving up on making an OS simulator
