Enabling the Pack in Video Settings
When running Minecraft with a shader loader such as Iris or OptiFine, you can switch BlendHer Shaders on directly from an active world. Press Escape to open the pause menu, choose Options, and click Video Settings. Open the Shader Packs menu (labeled Shaders in OptiFine), select BlendHer Shaders from your pack list, and confirm your selection so the game reloads its lighting engine.
Verifying Visuals and Balancing Performance
After the world reloads, check a nearby body of water and a sunlit tree or cliffside to confirm everything is active. Water should appear clearer and more reflective, while blocks should cast smooth shadows that match the current angle of the sun. If your frame rate drops while exploring bright daytime biomes, return to Video Settings and lower your vanilla Render Distance and Simulation Distance by a few chunks. Reducing the number of loaded chunks cuts down how many block shadows and water reflections your graphics card renders at once, keeping gameplay smooth without giving up soft shading, clean colors, or balanced sky lighting.
