Orbit Shaders runs on Iris and Sodium to bring deferred rendering and physical lighting effects to your world. Once the shader pack file is placed in your shaderpacks folder, you can activate it directly from the in-game menus without restarting.
Selecting the Shader Pack
1. Launch your game with both Iris and Sodium loaded.
2. Pause the game or start from the title screen, then navigate to Options and open Video Settings.
3. Click the Shader Packs tab at the top of the Sodium video menu.
4. Locate Orbit Shaders in the list of available packs, click it to highlight it, and press Apply.
5.
Verifying the Lighting Effects
Load into any biome during clear daytime to check that the shader pack is working properly. Look toward the sun through tree leaves to spot bright volumetric god rays scattering through the air. Next, inspect block corners and crevices for soft contact shadows created by Screen Space Ambient Occlusion, or place a torch to see its soft bloom glow. If the world appears unchanged, reopen the Shader Packs menu and confirm that shaders are toggled on rather than disabled.
