Troubleshooting Missing or Flat Sun and Moon Models

If you have enabled Cubic Stars in your resource pack menu but the sky still shows flat vanilla textures—or no sun and moon at all—a video setting or weather condition is usually hiding the 3D models.

Checking Sky and Celestial Video Settings

• Open Options > Video Settings.
• If you use performance or visual mods such as OptiFine or Sodium extras, check the sky or detail settings and make sure sky and sun/moon rendering are turned on.
• Raise your render distance slightly if thick horizon fog is hiding the sky during sunrise and sunset.
• Return to Options > Resource Packs and verify Cubic Stars sits in the Selected list above other texture packs.

Clearing Weather Obstructions

Rain and thunderstorms completely obscure celestial bodies in Minecraft, preventing you from seeing whether the cubic models loaded properly. Sleep through a storm in survival, or use the vanilla clear weather command in a cheats-enabled world to remove cloud cover right away. Once the sky clears, look up during daytime or nightfall to verify that the flat celestial textures have been replaced with three-dimensional cubic shapes.
