Refined Horizon Shaders FAQ
10 questions players actually ask, answered.
How do I enable the shader after installing it?
Open Options > Video Settings > Shaders, then locate Refined Horizon Shaders in your shader folder and select it. The shader will apply immediately to your world.
Why does my water look flat or not reflective?
Check your shader settings for Water Clarity and Reflection Intensity options—these may be set to low values by default. Increase both sliders in the shader configuration menu to see more dramatic water effects.
Can I make the leaves sway more or less?
Yes, open the shader settings and look for Foliage or Leaf Sway options to adjust the intensity and speed of wind effects on trees and tall grass.
The shader is making my game lag. What should I do?
Try lowering shadow quality, reducing water reflection detail, or disabling advanced lighting effects in the shader settings. You can also lower your render distance to improve performance.
Does this shader work with mods that add new blocks?
Refined Horizon Shaders works with most mods, but custom blocks from other mods may not receive the same lighting and reflection effects as vanilla blocks.
Why do caves and underground areas look too bright or too dark?
Adjust the Lighting and Ambient Effects settings in the shader menu—you can fine-tune how much light caves receive and how shadows appear in different biomes.
Can I use this shader with Optifine?
Refined Horizon Shaders is designed to work independently; using it alongside Optifine may cause conflicts or unexpected visual glitches.
How do I turn off specific effects like water reflections?
Open the shader configuration menu and look for toggles or sliders for individual features—you can disable water reflections, foliage sway, or biome lighting independently.
Does the shader affect my FPS in different biomes?
Yes, biomes with more foliage or water (like jungles and oceans) may impact performance more due to increased wind and reflection calculations; adjust shader settings accordingly.
Why do my screenshots look different from what I see in-game?
Screenshots may capture lighting differently depending on your in-game time of day and camera angle; try taking screenshots at different times or adjusting your video settings for consistency.
