The sun, moon and big planets are completely black when using the mod Astrocraft with SDV, and the sun is still rendered even if the vanilla option for the sun isn't enabled in SDV. Celestria's shooting stars are also black. (EDIT: they also render through distant horizon generated chunks with the shader enabled)

To reproduce this, just load the mods with SDV shaders enabled.

I expect the sun to be what it normally looks like when selecting the "vanilla" sun option in SDV, dissapear when I don't have that option enabled, and the big planets to have their textures. I also expect the shooting stars to have their normal texture.

• GPU: NVidia GTX 970
• Shader loader: iris-fabric-1.8.0+mc1.21.1.jar

Here are the features of Astrocraft if it helps:

-Real life constellations and stars
-Planets and their moons
-Realistic sun and moon positions, longer days or nights throughout the seasons
-Shooting Stars with annual Meteor Showers
-The Milky Way, galaxies, nebulae, and clusters
-Rare astronomical events such as eclipses
-Makes the spyglass useful
-Full customizability, with custom planets

(relevant) Features of Celestria:
Adds shooting stars and insomnia to everyone's favourite block game.

Shooting stars:
- randomly triggered serverside (only at night) and synced to all players
- server sends packet to client which then renders the shooting star (mixin into WorldRenderer)
