A light weight world heat radiation simulation engine, models thermal energy as discrete particles that emit from heat sources, propagate through blocks, and decay based on material conductivity.
Mod provided a client renderer to visualize heat particles, to enable this, editing client config enableHeatParticleRender to true. This also need to edit server config lazyHeatSync to false
Enabling particle rendering may cause severe performance degradation.
Features
- Heat particle simulation: particles emit from heat sources (lava, fire, campfires), move directionally through blocks, split at centers, and decay by conductivity
- Chunk-based caching: particles persist to chunk NBT when out of range, restore on re-entry, eliminating temperature drops on chunk reload
- Lightweight temperature queries:
SWHSimulationAPI.getTemperature()provides per-block readings without full particle sync; lazy sync mode further reduces network traffic - External registration API:
SWHRegistrateAPIlets other mods register block thermal properties without a hard dependency - Rich configuration: 24 server-side + 9 client-side config options with performance warnings for impactful settings
