What makes Octray different from other ray tracing shaders?

Octray uses an octree acceleration structure to trace rays efficiently, even at long distances. This keeps performance much better than standard ray tracing shaders.

What are the system requirements?

You need a decent GPU for ray tracing. Octray is optimized to be faster than most ray tracers, but it's still demanding. Test with basic ray tracing first to see if your card can handle it.

Will Octray work with other mods?

Yes. Octray is a shader, not a mod, so it works alongside most mods fine. Just avoid mods that change the rendering pipeline.

Q: Which Minecraft versions does Octray support?

It works with Minecraft 1.7.10 through 1.20.4. Download the version that matches what you're running.

Octray Shaders is a ray tracing shader pack that does things differently. Instead of the usual ray tracing approach, it uses an octree acceleration structure to cast rays efficiently across long distances. This keeps your FPS from crashing. It also includes solid denoising to keep the final image clean.

How It Works

Octree Acceleration

Octray traces rays using an octree structure. This skips over empty space instead of checking every single block a ray passes through. Result: fast ray tracing even at distance.

Advanced Raytracing

Uses a pseudo-recursive branching raytracer implemented in GLSL with a ray stack. The developer found a way to work around hardware limitations that most shader devs hit.

Denoising

Ray tracing produces noisy output at lower sample counts. Octray includes denoising to smooth out the image and get clean results.

Requirements

Required: Optifine
Optional: Iris Shaders Mod
