Calibrating In-Game Brightness for Spectrum Shader Lighting

Because Spectrum Shader overhauls both world coloration and lighting coloring, playing on the default maximum brightness can wash out shadows and night scenes. Adjusting your vanilla video brightness ensures the shader's custom lighting and under-block shadows appear as intended.

Setting the Recommended Brightness Level

1. Pause the game while inside a world or open Settings from the main menu.

2. Select Video from the left-hand navigation menu.

3. Locate the Brightness slider near the top of the video options.

4. Drag the slider until it sits between 50 and 80.

What to Check After Adjusting

• Under-Block Shadows: Walk under trees or roofed overhangs during the day. At the 50–80 brightness range, the shadows directly below blocks will look distinct without making caves completely pitch black.
• Day and Night Reflections: Check water and reflective surfaces during both daytime and nighttime cycles to confirm the sun reflection and custom lighting coloring are balanced.
• Dimension Fog: Enter the Nether or the End to see how the custom dimension fog blends with the adjusted brightness level.
