Changelog

Version: 2.1.2
Date: 2026-11-03
  Changes:
    - Glowing pipes connected to buildings, pumps or storage tanks now end with a smooth rounded glow instead of cutting off at the building's edge. Thanks Maxorio for the suggestion.

Version: 2.1.1
Date: 2026-10-25
  Bugfixes:
    - Fixed crash "LuaEntity doesn't contain key fluidbox" on Factorio 2.1.7 and newer (the game moved fluid access off LuaFluidBox onto LuaEntity).
    - Fluid and pipe-connection reads are now protected, so an API change can no longer crash the game.

Version: 2.1.0
Date: 2026-10-25
  Info:
    - Continued as Heat Glow (Reborn) by FallenPaladin. Original mod Heat Glow by OwnlyMe.
    - Updated for Factorio 2.1.
  Features:
    - Pipes now glow red-hot while they carry lava, molten iron or molten copper (Vulcanus).
    - Glow follows the pipe shape: straights, corners, T's, crosses, endings and pipe-to-ground entrances.
    - Works with Flow Control (elbow, junction and straight pipes, valves) and Color Coded Pipes (the glow sits on top of any pipe colour).
    - Settings: toggle the pipe glow, choose which fluids glow, brightness, and how fast pipes are re-checked.
    - Added /heat-glow-rescan command.
  Changes:
    - Helper functions are now local, so the mod no longer overwrites base game globals.
    - Every prototype change is guarded, so a missing entity no longer crashes on load.
    - Removed leftover backup graphics, smaller download.

Version: 2.0.2
