- Launch Minecraft.
- Go to Options → Video Settings → Shader Packs, then click Open Shader Pack Folder.

FAQ
- No lighting at night: Please use PBR resource packs. For vanilla style, SPBR is recommended. Otherwise, try Patrix.
- Can't load shaderpack: Please use Iris with version 1.7 or higher.
- Everything goes dark when turning back: This is due to the limitations of screenspace techniques. There isn't a perfect way to fix this.
- Intel GPU: Alpha Piscium uses cutting-edge graphics technology. Unfortunately, Intel doesn't maintain their OpenGL driver well, so Intel GPUs are not supported.
- AMD GPU: Check if your GPU driver is newer than 22.7.1. If older, please update your driver.
- Other loading errors: Press Ctrl+D in Iris's shaderpack selection screen, then reload the shaderpack. Make an issue with the error message and the relevant files in
.minecraft/patched_shadersas shown in the error message.
