Composition Shaders FAQ
10 questions players actually ask, answered.
How do I turn on the composition overlays?
Open your shader settings menu (usually accessed through the Shader Options button in Video Settings) and look for the Composition Shaders toggles. Enable the overlay type you want—Rule of Thirds, center guides, or videography frames—and it will appear on your screen immediately.
Can I use multiple overlays at the same time?
Yes, most overlays can be enabled together, though having too many active simultaneously may clutter your view. Experiment with different combinations in the shader settings to find what works best for your framing needs.
Do these overlays show up in my screenshots or recordings?
No, the overlays are purely visual guides on your screen and do not appear in saved screenshots or video files—they're only there to help you compose your shot before you capture it.
How do I adjust the overlays for my monitor's aspect ratio?
Go to the Composition Shaders settings and look for aspect ratio or resolution options. Select your monitor's aspect ratio (16:9, 21:9, 4:3, etc.) and the guides will recalculate to match your screen proportions accurately.
Will these shaders hurt my FPS?
Composition Shaders is designed to be lightweight and should have minimal impact on performance since it only renders overlays on top of vanilla rendering. You may see a negligible frame rate difference depending on your hardware.
Can I hide the overlays temporarily without turning them off?
Most shader packs include a hotkey (often a function key) to toggle overlays on and off quickly. Check your shader settings or in-game controls menu to find or rebind the toggle key.
Do I need OptiFine or Iris to use Composition Shaders?
Composition Shaders requires a shader loader like Iris or OptiFine to function. Make sure you have one installed before loading the shader pack.
Why do my overlay guides look stretched or misaligned?
This usually means your aspect ratio setting doesn't match your actual monitor resolution. Go back to the shader settings and select the correct aspect ratio for your display.
Can I customize the color or opacity of the overlay lines?
Yes, Composition Shaders typically includes settings to adjust overlay opacity, color, and line thickness. Look in the shader options menu for customization sliders.
Do these overlays work in third-person and first-person view?
Yes, the composition guides display in both camera modes, though you may need to adjust your framing approach depending on which view you're using for your content.
