What's Changed?

• Added a minAlpha field for properties.
• Added a timeShift vector for the rotation object (By default, FSB starts rotation at 0 tick time, while OptiFine does so at 18000 tick time. This vector allows us to shift the start time for our rotation).
• Added an experimental multi-texture skybox type (wiki section).
• Added contributing guidelines and a code of conduct.
• Allowed fog color modification to also modify fog density.
• Added a configuration file (.minecraft/config/fabricskyboxes-config.json).
  • Saves enable state.
  • Added a keepVanillaBehaviour flag.
• Fixed the URL issue when using Sinytra Connector (#96).
• Fixed the alpha rendering for the end skybox type.
• Added a debugging HUD (Keybind is unbound, meant for resource pack authors).
• Added vi_vn translations (#94) by @ImVietnam in https://github.com/AMereBagatelle/fabricskyboxes/pull/94.
• Improved performance for several skybox types.
• Fixed cyclic fade alpha calculation.

What's changed?

• Reverted the "Fix triangles appearing on low render distance" patch.
  • This change was reverted because it caused unintended blend effects. The triangles appear due to being clipped by the fog which is also visible in Vanilla's end sky.
• Added a new fog transition using alpha blending.
• Fixed missing dark sky in overworld skybox type (occurs when falling through the void).
• Improved alpha calculation.
• Added configuration to toggle FSB, which now gets saved.
• Normalized fade values.
• Added the biome_rain weather condition, which detects if the biome is actually raining.

Breaking changes

• Removed Skybox#isActiveLater from the API.

What's Changed

• Fixed the issue where render distance was lowered using mono-color skyboxes with Iris
• Correct rotationSpeedZ to roll in docs by @supsm in https://github.com/AMereBagatelle/fabricskyboxes/pull/87

Full Changelog: https://github.com/AMereBagatelle/fabricskyboxes/compare/0.7.0-mc1.19.4...0.7.1-mc1.19.4

What's Changed

• Improved and moved custom blend mode into blender object. More information can be found here.

  • Add support for blend function separate.

• Added overworld and end skybox type (#80)

  • overworld skybox type will render the vanilla overworld sky + sunset/sunrise hue.
  • Modified sunrise/sunset fog to match decorations rotation.

• Improved decorations rendering (#80)

  • In theory resolves #54
  • Allow more than 1 decoration to be rendered.
  • Add blending for decorations.

• Added decorations and disable blending modes (#80)

  • decorations is the default blending mode for decorations.
  • disable blend mode does as named.

• Improved rotation (#79)

  • Fixed rotation precision, this resolves #83.
  • Added rotationSpeedX and rotationSpeedZ for controlling pitch and roll.
  • Renamed rotationSpeed to rotationSpeedY and removes its hardcoded offset. Previously, rotationSpeed controlled yaw rotation but with the addition of rotationSpeedX and rotationSpeedZ, users can now easily control all three axes of rotation without the need to abuse axis/static.
  • Users can still use axis/static alongside rotationSpeedY if they wish to simulate rolling or pitching.
  • Removed shouldRotate property from properties. The rotation axes can now be determined in the rotation object, where all rotation speed axes are set to 0 by default.
  • Added skyboxRotation toggle in rotation object, the sun/moon speeds up and slows down when rotating in certain areas(sunset/sunrise hue) and it affects rotation. It's enabled by default for all skybox rotation objects and disabled by default for all decorations rotation object.

• Fixed monocolor sky type

  • Added blend object for monocolor

• Mark fade times optional (mainly just to avoid setting fade times just to use alwaysOn)

• Fixed weather condition checks

• Fixed dimensions condition not following specification

• Fixed triangles appearing on corners of skyboxes under low render distances.

Disabled changes

• Iris API/sun path rotation by IMS212
  • Temporarily disabled as it's a difficult problem to solve when you want to do stuff and shader packs what to do something else.
