Northstar Sable Iris Horizons Bridge

The bridge addresses rendering conflicts that appear when Northstar skies are combined with shader packs. Shader packs can hide Northstar's custom sky layers or draw the Sun and Moon with the wrong transparency, and volumetric clouds, fog and cloud shadows can show up in space dimensions that Northstar sets to no clouds. The bridge restores the planet masks and custom sky layers, keeps the sky elements visible where Northstar expects them, and respects its dimension-specific Sun and Moon rules. Mars and Venus keep the atmospheric behaviour Northstar intends, and the Venus acid rain receives shader-side handling.

Distant Horizons is handled so that terrain stays visible near a planet's surface, and its level of detail gradually drops away during the climb instead of ending abruptly. Clean black space backgrounds are preserved where appropriate. With Sable installed, physical structures can cross Northstar's planet-transfer boundaries together with their passengers, and lightweight Sable structures react to Martian weather. The integrations activate only when the matching mod is installed, and the settings are grouped into understandable pages.

The mod requires Create: Northstar - Redux, which provides the Northstar planets. It is published for NeoForge 1.21.1 and is released under the MIT License, so it is not open source. It runs on client or server, and both are optional.
