How to Turn On Sakura Prime Shader and Check That It Is Working

Sakura Prime Shader is a shader pack. It needs a shader loader such as Iris or OptiFine. It will not load from the normal Resource Packs screen.

Loading the pack

1. Launch Minecraft with Iris or OptiFine active.

2. From the title screen or the pause menu, open Options → Video Settings → Shader Packs. On some Iris setups this is reached from the Video Settings screen as well.

3. Click Open Shader Pack Folder and confirm the Sakura Prime Shader file is inside the shaderpacks folder. It does not go in resourcepacks.

4. Back in the list, select Sakura Prime Shader and click Apply or Done.

5. A short freeze on first load is normal.

Confirming it loaded correctly

Step into a world and look around. You should see these signs:

• A pink-tinted sky during the day instead of vanilla blue.
• Mist and fog around mountains and distant terrain, often with a soft pink hue.
• Shadows that stay readable. Dark areas look softened rather than pitch black.

If the sky is still plain blue, the pack did not apply. Reopen the Shader Packs screen and make sure it is selected rather than "Off" or "(internal)". If the screen goes black or the game reports an error, try the other loader. You can also switch off other shader-related mods to see if one is conflicting.
