Using Cubic Stars Together with Shader Packs

When running shaders through a loader such as Iris or OptiFine, you may notice the 3D cubic sun and moon disappear and get replaced by smooth, circular light effects. Many shaders hide vanilla celestial models by default, so you need to adjust your shader settings to bring Cubic Stars back.

Enabling Vanilla Celestial Rendering

• Open Options > Video Settings and go into your Shader Packs or Shaders menu.
• Select your active shader and open its Shader Pack Settings or Shader Options screen.
• Open the sky, atmosphere, or celestial submenu.
• Turn off the shader's custom sun and moon textures, or turn on the option that renders default vanilla sun and moon models.
• Apply the changes and return to your world.

Balancing Sky Glare and Depth

Once the shader stops overriding vanilla celestial bodies, Minecraft will render the 3D models from Cubic Stars alongside your shader lighting. If bright bloom or lens flare washes out the edges of the cubic sun during sunrise and sunset, revisit the shader's lighting settings and lower the sun glare or bloom slider until the three-dimensional shape is clearly visible.
