Atmospheric Shaders

Atmospheric Shaders is a shader pack focused on sky rendering and lighting.
It is designed to work with SimpleClouds and keeps visuals close to vanilla while improving atmosphere behavior.

What it changes

Sky and lighting

The sky uses smoother gradients and better horizon blending.
Light diffusion and sky color transition more gradually across the day.

SimpleClouds integration

Clouds react to time of day and lighting conditions.
They are visually blended into the sky instead of appearing as a separate layer.

Weather awareness

Sky brightness and color shift based on weather and biome context.
Storms and clear weather produce different ambient tones.

Visual style

Colors are kept balanced.
Bloom and post effects are limited to keep the image readable and stable.

Day and night transitions

Dawn and dusk transitions are smoother with more natural color shifts.

Performance

Effects are conservative and lightweight.
The pack is intended to remain stable and usable on a wide range of systems.

Planned changes

Cloud visuals will be refined further.
Water and fog behavior will be improved.
Sky scattering and sun coloration will be adjusted.
Some visuals may later react to weather data such as storms or humidity.

SimpleClouds compatibility notice

If you are using this with SimpleClouds, be aware that there are many incompatibilities.

Before going to the comments saying that this mod does nothing, read this.

Mods like Alexs Caves, Immersive Engineering, Distant Horizons and others break the fragile balance of the rendering pipeline.
This results in depth and scene composition issues.

I have been working on a fix for a long time but have not found a proper solution yet.

If you are comfortable with GLSL or Java and think you might have an idea, feel free to help.
