š Flux Shaders v0.2.3-ALPHA
A big update over the pre-alpha: the code was reorganized, and you now get an in-game settings menu, a proper moon and motion blur.
⨠New
- In-game settings menu ā new options screen with English labels and descriptions.
- Fog toggle ā turn the distance fog on or off.
- Motion blur ā new slider (0 = off, up to 10). Works when you move or turn the camera. Disabled by default.
- Custom moon ā the moon is now a round disk with a soft blue edge glow and subtle surface details.
- Moon glow in the sky ā a faint bluish glow around the moon at night.
- Post-processing pipeline ā added composite and final passes (used for motion blur and color grading).
š§ Improved
- Color grading moved to a final post-processing pass, so it now affects the whole image (sky, terrain, sun and moon), not just blocks.
- Fog is now calculated from the real distance to the camera, giving a more even look.
- Sun and moon rendering are now cleanly separated.
- Higher color precision (RGBA16F) for smoother gradients and less color banding.
- Cleaner code ā shared functions were moved into separate library files (sky, vignette, tonemap, motion blur, settings), making the pack easier to maintain.
ā ļø Notes
- Still an early alpha ā bugs and visual glitches may appear. Please report them!
