Once the shader pack is placed in your shaderpacks folder alongside a compatible shader loader such as Iris or OptiFine, you need to enable it through your video menu to apply its lighting and shadow changes.
Selecting the Shader Pack
1. Pause the game or start from the title screen and open Options.
2. Click Video Settings, then open the Shader Packs (or Shaders) menu.
3. Click SomeRandomPhoto Shaders from the list so it highlights.
4.
Confirming Everything Loaded
Load into an Overworld save during daytime to verify the pack is active while keeping the classic blocky look intact:
- Check the ground near trees, buildings, and wandering mobs to confirm soft, clear shadows are being cast across the terrain.
- Walk up to a river, lake, or ocean and angle your camera toward the horizon to see smooth water reflections picking up both sunlight and nearby terrain.
