Primal Glow High Shaders FAQ

Open your shader settings menu in-game (usually accessed through Video Settings), find the Shaders option, and select Primal Glow High from the list. Once applied, the shader activates immediately and you'll see the warm lighting and glow effects take effect.

Primal Glow High improves cave visibility but respects vanilla darkness in unlit areas. Place torches or other light sources to see the shader's ambient glow and shadow softening work properly—the shader enhances existing light rather than creating it from nothing.

Primal Glow High works with most mods, but avoid running multiple shaders at once as they conflict. Mods that add custom blocks or lighting may interact unpredictably, so test your setup and check community reports if you experience visual glitches.

Refer to the performance optimization guide for your setup—you can reduce shadow quality, lower render distance, or disable certain effects through the shader's settings menu. Start with these adjustments before lowering your overall graphics settings.

Yes, the shader applies to all dimensions. The Nether gets warm ambient glows that complement its existing colors, while the End receives adjusted sky and lighting that maintains visibility without breaking the dimension's atmosphere.

Primal Glow High gives light-emitting blocks a distinctive radiance and glow effect that's more pronounced than vanilla. This is intentional and helps them stand out in builds—if you prefer subtler glows, check the shader settings for glow intensity options.

Primal Glow High automatically adjusts its lighting based on the time of day, but you can fine-tune how it looks during specific times through the shader settings menu. Refer to the day/night adjustment guide for specific controls.

Shaders are client-side only, so Primal Glow High only changes how you see the world—other players won't see your shader effects unless they install it too. Your builds look the same to them as they would without any shader.

Shadow softness depends on your shader settings and the time of day—high sun angles create sharper shadows while low angles soften them naturally. Adjust shadow quality in the shader menu if the effect feels wrong for your preferred aesthetic.

The shader is designed to be relatively lightweight, but performance depends on your hardware. Start with the performance optimization guide and lower settings incrementally—you may need to reduce shadow quality or render distance on older systems.
