Celeritas/Nothirium Extra

Added

• Added optional Modern Clouds, a backport of Minecraft 1.21.6's updated cloud pattern and horizon-scale renderer.
  • Uses circular coverage and a distance fade instead of ending at a visible square boundary.
  • Uses the existing Cloud Distance setting and keeps the same physical range as the legacy renderer.
  • Leaves custom dimension cloud renderers in control and falls back to the normal cloud path when the modern renderer cannot be used.
  • Requires AssetMover 2.5 or newer to acquire the cloud texture. The option remains unavailable until both AssetMover and the texture are present.
• Added unit coverage for cloud range calculations, texture-cell classification, and modern cloud mesh generation.

Changed

• Raised the minimum Cleanroom Loader version to 0.6.0-alpha.
• Declared Cleanroom and Celeritas as required loader dependencies and AssetMover as an optional ordered dependency.
• Extended Cloud Scale from 0.25x through 4.00x; 1.00x remains the vanilla scale.
• Added a Default value to Cloud Height that follows the current dimension's cloud height instead of imposing a fixed height.
• New configurations enable Steady Debug HUD by default with a one-tick refresh interval. The interval can be adjusted from 1 to 20 ticks.
• Modern Clouds is independent of Celeritas's Use Faster Clouds option. When Modern Clouds is disabled, Celeritas's normal fast-cloud behavior is preserved.
• Reworked the star, particle, armor-stand, beacon-beam, item-frame-name, and rain-splash hooks to preserve more of the original rendering paths.
• Replaced per-frame object allocations in extended FPS statistics collection with reusable sample buffers.
• Updated the build configuration, UniMined 1.4.26-kappa, and Shadow 9.5.1 while retaining Java 25 as the target.

Fixed

• Made the cloud-pass projection and fog range account for the effective cloud distance, cloud scale, camera height, and current dimension's cloud height.
• Corrected Steady Debug HUD caching to target Minecraft 1.12.2's actual debug-overlay text providers and use monotonic refresh timing.
• Corrected screen-mode detection to read the live windowed, borderless, or fullscreen state instead of relying on cached state.
• Corrected the item-frame name-tag option to intercept the item frame's actual name-rendering path.
• Prevented a failed configuration load from saving a partially populated configuration over the existing file.

Removed

• Removed Hide HEI Until Searching, including its setting, Mixin, translations, JEI compile dependency, and optional-Mixin registration.
• Removed the Void Particles option.
• Removed the no-op CoreMod loading plugin and stopped registering the unused Access Transformer. Celeritas Extra now relies on its single Sponge Mixin configuration.
