Frequently asked questions

How do I turn on Ultimate Horror Experience Shaders in game?
Open your Video Settings, navigate to the Shader Packs menu, and select Ultimate Horror Experience Shaders from the list. Make sure you are running a shader loader like Iris or OptiFine, otherwise the Shader Packs menu will not appear.
Why are my torches and lanterns glitching and dimming randomly?
This is the shader's built-in flickering lights feature, not a lighting bug. Light sources intentionally dim and glitch unexpectedly to make dark areas feel unstable and keep you on edge.
Can I turn off the sudden flashes for photosensitivity?
Open your Shader Pack Settings menu to toggle or tone down sudden flashes and flickering effects. Adjusting these options lets you keep the creepy shadows and cold color grading without harsh strobe-like lighting.
Why is the edge of my screen blurry with split colors?
That effect is chromatic aberration combined with vignette shading, which darkens the corners and splits colors along your screen borders to narrow your sight. If it causes eye strain during long play sessions, you can reduce or disable both filters in the Shader Pack Settings.
