Heat-resistant Pipes required for molten fluids (lava, molten metals). Regular pipes/tanks/pumps are instantly destroyed by molten fluids. Heat-resistant Pipes have smaller network size (default: 32 segments). Settings for max network size (1-320) and player collision. Licensed under MIT.
Mods introducing new content into the game.
Version: 2.0.1
Date: 2025-11-19
Optimizations:
- Performance improvement by adding smart caching
- Segments containing only heat-resistant pipes are now cached as "clean" and skipped during scans
- Cleanup operations are now spread across multiple ticks to prevent UPS spikes
Version: 2.0.0
Date: 2025-11-19
Changes:
- Renamed to Mod name to "Heat-resistant Pipes"
- Complete rewrite with optimized hybrid scanning system
- Regular pipes, tanks, and pumps are INSTANTLY DESTROYED when they contain molten fluids
- Removed complex foundry variant system - all foundries now use standard "foundry" entity
- Foundries and offshore pumps accept both regular and molten connections
- Auto-detects molten fluids (any fluid with "molten" or "lava" in name)
Optimizations:
- Three-tier scanning system: queue processing → foundry priority → round-robin backup
- Fluid system ID caching - skips checking pipes in known-safe networks
- Only tracks foundries for priority checking
Settings:
- New: Debug Mode (runtime, per-user) - enable diagnostic info
- Existing: Max network size, player collision, fluid whitelist/blacklist
Migration:
- All custom foundry variants automatically convert to standard foundry
- Recipe, rotation, modules, and fluids are preserved during migration
- Heat-resistant pipe properties unchanged (graphics, recipe, max extent)
Breaking Changes:
- If you have molten fluids in regular pipes/tanks/pumps, they will be destroyed on load
API:
- Added remote interface: HotPipesFork.register_fluid_category, HotPipesFork.register_fluid, HotPipesFork.register_entity_compatibility
- Other mods can register custom fluids and pipe types
Version: 1.2.8
Date: 2025-10-05
Bugfixes:
- Allow copy and paste from custom foundries.
Version: 1.2.7
Date: 2025-10-05
Bugfixes:
- Better handling of quality. Manual upgrading of custom foundries works now (shift click with higher quality foundry in hand). However, I can't get upgrade planner to work for the custom foundries, let me know if you know how to get that working.
Version: 1.2.6
Date: 2025-09-19
Compatibility:
- Added compatibility with Plasma Industries
Bugfixes:
- Fixed: Base foundry outputs now correctly accept both "default" and "molten" fluids.
- Fixed: Ensured foundry variants (mixed, molten) still have correct fluid box categories.
Version: 1.2.5
Date: 2025-09-18
Bugfixes:
- Fixed foundry rotation not being preserved during automatic conversions.
- Improved module preservation with better slot positioning and quality handling.
- Enhanced error handling for state restoration with user notifications.
- Fixed rotation and modules being lost when loading saves from older mod versions.
- Added custom migration system that preserves foundry state during mod upgrades.
Version: 1.2.1
Date: 2025-09-16
Changes:
- Improved foundry compatibility: foundries now dynamically adapt their fluid connections based on recipe requirements (molten-only, mixed, or standard fluids).
- WARNING your Foundries might have been rotated! Sorry!
Version: 1.2.0
Date: 2025-08-16
Bugfixes:
- Both foundry outputs can now output concrete mix when using crushing industries.
- Outputting molten metals is now really only possible in heat resistant pipes.
- WARNING for Crushing Industry and Vulcanus Parched users, your Foundries which are using Lava recipes might have been rotated!
