qUINT MXAO
Ambient occlusion. Contact shadows that keep objects sitting on the ground.
00No post-processing
PrismShade adds real post-processing to Roblox on your Mac. This island starts out flat, like the default game. Scroll down and each pass gets added, one at a time.
01qUINT MXAO
Ambient occlusion darkens the places light can't reach: under the roof, where the steps meet the sand, between the rocks. Things stop looking like they float.
02qUINT SSR
Screen-space reflections run over the whole frame. The pool picks up the pavilion, the floor picks up the pillars, and the grass gets a faint sheen. Whatever is off screen falls back to the sky.
03iMMERSE Pro RTGI
Sunlight hits the sand and the water and spills that color onto the stone around it. Bounce light is a big part of why a place looks lit instead of just colored.
04qUINT ADOF
Depth of field softens the background the way a real lens does. You set where the focus sits and how strong the blur gets.
05qUINT Bloom
Bloom only touches the hottest parts of the frame: the sun, the lamps, these crystals. The rest stays sharp.
06qUINT Lightroom + Deband + Clarity
Temperature, contrast and a touch of color separation, here pushed cool and blue. Deband smooths out the sky, and Clarity brings back small detail.
07Full stack
Turn any pass off in the stack to see what it was doing. In game, F8 opens the same kind of overlay.
