Oct-Path is a Minecraft shaderpack based on Octray Rewrite, an open source ray tracing shader developed by BruceKnowsHow.
"Octray Rewrite" is an innovative ray tracing shader that supports unlimited render distance, i.e., raytracing the entire render distance (64x chunks, 384 height), and allows casting long distance rays at high speeds by implementing an Octree-like acceleration structure for ray tracing.
While "Octray Rewrite" has an excellent ray tracing mechanism, it was incomplete because it omitted drawing entities and omitted translucent processing including water, and so on. Therefore, Oct-Path was born to take advantages of this shader while not interfering with Minecraft gameplay.
As a precondition, OptiFine is installed
so the shaderpacks folder is opened.
Special thanks to BruceKnowsHow who developed "Octray Rewrite".
"Octray Rewrite" has been declared open source by the author, and moreover, BruceKnowsHow has also given his approval when I released Oct-Path, saying "Yep, you are free to release it".
Written by Puppy_Mud. Read it with pictures on Modrinth.
Install Iris (with Sodium) or OptiFine for your Minecraft version: shaders need one of them.
Download the .zip file from Modrinth. Do not unzip it.
In Minecraft, open Options, then Video Settings, then Shader Packs, and click Open Shader Pack Folder.
Drop the .zip file into that folder, pick Oct-Path in the list and click Done.
Shaders are heavy on the graphics card. If the game gets slow, pick a lower profile in the shader settings.
