Frequently asked questions

How do I enable RTUShader after installing it?
Open Options > Video Settings > Shaders, then locate and select RTUShader from the list. Click Apply and the shader will activate immediately in your world.
Why does my world look too dark or too bright with this shader?
Use the shader's built-in brightness and contrast settings in the shader options menu (accessible via the Shaders button in Video Settings) to adjust the overall lighting to your preference.
Can I use RTUShader with other visual mods like Optifine or Sodium?
RTUShader works best with Iris (a shader loader designed for modern Minecraft), though compatibility depends on your specific mod setup; always check mod documentation for known conflicts.
How do I customize the water to look more transparent or reflective?
Open the shader options menu and look for water-related settings such as water transparency, reflection intensity, or wave height to adjust the appearance to your liking.
