Changelog

Version: 1.1.4
Date: 2026-11-01
  Changes:
    - Added space-breeze as a recommended dependency. It is enabled by default but can be turned off.

Version: 1.1.3
Date: 2026-11-01
  Bugfixes:
    - Fixed smoke staying permanently after a building was replaced by another mod (for example a quality upgrade done by script). Removals that raise no mined or destroyed event are now detected.
    - The mod now also listens to script_raised_destroy and script_raised_revive.
    - Machines that no longer exist are pruned from tracking in the background, so their smoke emitters are always cleaned up.
    - Rescanning (loading with changed mods, changing relevant settings, /ps-reload) now also removes emitters that were no longer tracked, which clears lingering smoke from existing saves.

Version: 1.1.2
Date: 2026-06-27
  Features:
    - Updated for Factorio 2.1
    - Fixed changelog

Version: 1.1.1
Date: 2026-05-19
  Compatibility:
    - Compatibility for chimney for configurable-arc-furnace

Version: 1.1.0
Date: 2026-05-17
  Features:
    - Added startup settings to control the random spawning boundaries for low-lying body smog.

Version: 1.0.0
Date: 2026-05-17
  Features:
    - Added extensive startup settings to customize colors, alpha transparency curves, and independent density scales for chimney smoke, body smog, and exhaust plumes.
    - Added runtime settings to toggle the dark exhaust plumes or adjust the specific pollution tier where they begin spawning.
    - Added dynamic smoke scaling support for burner-generator entities, enabling proper boiler-style smoke scaling for AAI Industry's burner turbines.

Version: 0.9.1
Date: 2026-05-15
  Features:
    - Added dark pulsing exhaust plumes for Tier 5+ machines and improved smog transparency for better factory visibility.
    - Boiler smoke now accurately reflects partial load — boilers kept warm by solar panels show proportionally less smoke.
    - Added entity blacklist setting: enter comma-separated entity names to exclude them from smoke emitters.
    - Machines with vanilla smoke (boiler, stone-furnace, steel-furnace, burner-mining-drill) no longer show duplicate smoke from the base game.
    - Added chimney support for AAI Industry burner machines and offshore-burner mod pump, when those mods are present.
  Bugfixes:
    - Fixed occasional light flicker from emitters at higher tiers.

Version: 0.5.4
Date: 2026-05-12
  Bugfixes:
    - Emitters are no longer picked up by mods like RateCalculator.

Version: 0.5.3
Date: 2026-05-03
  Bugfixes:
    - Emitters no longer act as a light source at night.

Version: 0.5.2
Date: 2026-05-03
  Bugfixes:
    - Fixed an issue where placing a chimney smoke emitter could silently remove nearby ghosts.

Version: 0.5.1
Date: 2026-05-03
  Features:
    - Initial release.
    - Tracks all pollution-generating machines across all surfaces.
    - Smoke particle count and type (light/heavy) scale with actual pollution output per machine.
    - Module and beacon effects on pollution are reflected in real time.
    - Chimney-mode for machines that have real chimney art: boiler, oil-refinery, chemical-plant, and Space Age machines recycler, foundry, cryogenic-plant, heating-tower. Smoke spawns at per-direction chimney offsets rather than entity centre.
    - All other polluting machines use random-spread mode across their bounding box.
