Written by Nachtwind1. 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 Optimism-shader 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.
