Preview edits of the Cinematic preset — simulated looks, not live renderer output.

What it does

Every frame, rebuilt from light.

Soft shadows

Directional sun with per-block occlusion. Edges get a natural penumbra instead of a hard black cut, and they tighten as objects get closer.

Screen-space reflections

Water, glass and polished stone pick up the sky and the light around them, at half resolution with a temporal filter so it stays cheap.

Volumetric air

Height fog and light shafts give distance its depth — the sun finally reads as a light source instead of a painted disc.

FAQ

Questions people actually ask

Is RtxBlox free?

Yes. The shader pack is free to download and use — no account, no subscription, no in-app store.

Will this get me banned?

RtxBlox only changes what your GPU draws; it does not touch gameplay, input or server traffic. That said, client-side modification is a grey area in Roblox's terms — use it at your own discretion.

How much FPS will I lose?

Roughly 8–15% on Balanced versus default lighting, and about 4% on Performance. Ultra is meant for screenshots, not for playing.

Windows says "unknown publisher".

SmartScreen flags new binaries before it has reputation data. Download only from this page; if it complains, choose More info → Run anyway.
