Turn On Luminia Shaders in Your World

Luminia Shaders is a shader pack. It needs a shader loader such as Iris or OptiFine to run. Once the loader is installed, enabling the pack takes a minute.

Put the Pack in the Right Folder

1. Launch Minecraft with your shader loader active.

2. Open Options > Video Settings > Shader Packs.

3. Click the button that opens the shader pack folder. This is the shaderpacks folder, not the resourcepacks folder.

4. Move the Luminia Shaders file into that folder. Leave it zipped unless your loader asks otherwise.

5. Return to the game. The pack should now appear in the list.

Activate and Check It

1. Select Luminia Shaders in the list and click Apply or Done.

2. The screen may freeze briefly.

3. Load a world and check that the shader is working:

• Stand near a torch or lantern. Nearby walls and floors should pick up colored light.
• Look under a tree or an overhang. You should see soft, realistic shadows.
• Walk past a mob. Mobs also cast shadows with this pack.

If the world looks exactly like vanilla, the pack is probably not selected. Go back to the Shader Packs screen and make sure Luminia Shaders is highlighted rather than "Off" or "Internal."

To compare with vanilla at any time, switch the pack off in the same menu and switch it back on again.
