Complementary Shaders Mod (1.21.7, 1.20.1) is a refined shader pack built upon the foundations of BSL Shaders but optimized for beauty, stability, and high compatibility. This shader pack enhances Minecraft’s visuals in all the right ways: better lighting, smoother shadows, realistic fog, upgraded skyboxes, and vibrant color profiles that work well for both gameplay and cinematic builds.
More than just visual upgrades, Complementary focuses on giving players a flawless and consistent experience across all platforms. Whether you’re playing with mods, on older GPUs, or in high-resolution survival worlds, this shader is designed to “just work” without glitches, lighting bugs, or strange effects.
Compatible with OptiFine, Iris Shaders, and Sodium Mod, this pack blends visual quality with high framerates and broad hardware support.

Why Choose Complementary Shaders?
Unlike many shader packs that either overdo effects or cripple your framerate, Complementary Shaders achieves a rare middle ground: clean visuals, minimal bugs, and excellent performance.
It was created to fix what other shaders often get wrong: extreme glare, washed-out colors, broken mod compatibility, or flashing textures. Complementary reduces noise and gives you control over nearly every effect, letting you build, explore, or film without distraction.
It’s also one of the few shaders to feel truly “vanilla-plus” enhancing Minecraft’s natural look rather than transforming it into a different game.
