FAQ

• No lighting in the night: Please use a PBR resource packs. For vanilla style, SPBR is recommended. Otherwise, Patrix.
• Can't load shaderpack: Please use Iris with version 1.7+.
• Everything goes dark when turning back: This is due to the limitation of screenspace techniques, there isn't a perfect way to fix this.
• Intel GPU: Alpha Piscium uses cutting edge graphics technology. Unforunately Intel doesn't maintain their OpenGL driver well. Thus can't support Intel GPU.
• AMD GPU: Check if your GPU driver is newer than 22.7.1, if older please update your driver.
• Other loading error: Press Ctrl+D in Iris's shaderpack selection screen. Reload the shaderpack. Make an issue with the error message and the relevant files in .minecraft/patched_shaders as shown in the error message.
