SmartSmelt

High-performance, preset-based smelting accelerator for Rust (uMod/Oxide) with automation-safe behavior, smart fuel pull, and population-aware AutoTune scheduling.

Current version: 1.2.4

Designed for modded servers (2x–1000x+), heavy conveyor automation, and wipe-day peak usage.

• Preset-based acceleration: 2x, 3x, 5x, 10x, 25x, 50x, 100x, 1000x, Instant
• Single global loop (no per-oven timers)
• Adaptive scaling: processes more ovens per loop as load increases
• Dynamic loop interval: automatically adjusts tick interval based on active ovens
• Smart fuel auto-pull: pulls only the additional wood needed (delta-based)
• Consistent wood-only burn: lit furnaces follow the selected preset even without ore
• Mixing-table acceleration: recipes use the same selected preset as furnaces
• Native-rate accounting: accelerated idle burn adds only the amount above Rust's built-in 1x consumption
• Mixed-ore fuel top-up fix: adding a second ore type triggers a NextTick recalc
• Large furnace fuel balancing: distributes wood across fuel slots
• Charcoal overflow control: Skip (automation-friendly) or Pause (vanilla-strict)
• AutoTune: set average population + bias and let SmartSmelt tune scheduling
• Ore splitting toggle: enable/disable input-slot splitting
• Minimal spam by default; debug tools when needed

SmartSmelt avoids the classic “timer per furnace” approach. Instead it:

1. Tracks active ovens in a lightweight dictionary.
2. Runs a single global loop that processes up to a capped number of ovens per pass.
3. Uses a snapshot list rebuilt only when the tracked set changes.
4. Uses a round-robin cursor to prevent starvation.
5. Optionally adjusts global loop interval dynamically based on load.

This keeps CPU predictable even with hundreds of active ovens.

1. Place SmartSmelt.cs into:
   • oxide/plugins/
2. Reload:
   • oxide.reload SmartSmelt
3. Edit config:
   • oxide/config/SmartSmelt.json

• /ss.info
  • Shows plugin status, AutoTune status, and effective scheduling values
• /ss.debug
  • Enables additional debug logging (use briefly)

"Preset": "10x"

Supported: 2x, 3x, 5x, 10x, 25x, 50x, 100x, 1000x, Instant

AutoTune automatically selects scheduling settings based on your AveragePopulation and Preset.

"AutoTuneEnabled": true,
"AveragePopulation": 300,
"AutoTuneBias": "Balanced",
"AutoTuneWriteToConfig": false

Bias modes:

• Balanced — default behavior (recommended)
• Performance — more conservative (reduces hitch risk)
• Responsiveness — more aggressive (snappier updates)

AutoTuneWriteToConfig

• false (default): runtime-only tuning; config stays as you wrote it
• true: writes the chosen scheduling values into the config so you can see them

"EnableOreSplitting": true

SmartSmelt 1.2.4 and newer enforce conservation during furnace and refinery distribution: the amount added to destination slots can never exceed the amount deducted from the incoming stack. Uneven pre-existing stacks are filled safely without creating additional ore or crude oil. Direct drag/drop, quick move, hover-loot/H-key transfers, and other post-transfer inventory routes are all rebalanced through the same conservation rule. In mixed-ore furnaces, the newly added ore type uses its existing slots plus any empty input slots without moving the ore types the player already arranged.

• true: distributes moved ore across input slots (when safe)
• false: respects vanilla stacking, but fuel auto-pull still works

"EnableMixingTableScaling": true

• true: mixing-table recipe duration follows the selected SmartSmelt preset.
• false: leaves mixing tables at Rust's vanilla speed.
• The setting is added automatically during upgrades without replacing existing administrator preferences.

"CharcoalOverflowMode": "Skip"

• Skip (recommended): prevents automation stalls
• Pause: vanilla-strict behavior (can stall under heavy charcoal congestion)

"ReducedWoodCostEnabled": false,
"WoodCostScale": 0.5

• When disabled, fuel and charcoal production follow the selected preset normally.
• When enabled, WoodCostScale controls the accelerated portion of wood consumption.
• Existing configuration values and administrator preferences are preserved during normal upgrades.

• Use AutoTuneEnabled = true
• Set AveragePopulation to your real peak (not average daily)
• Prefer Bias = Balanced (or Performance on weaker hardware)
• Keep CharcoalOverflowMode = Skip for conveyor-heavy servers

• Smelting feels “bursty” at peak:
  • Lower DynamicMaxGlobalLoopInterval slightly or increase AdaptiveMaxOvensPerTick (only if CPU allows)
• Periodic hitches:
  • Lower AdaptiveMaxOvensPerTick first, then raise DynamicMaxGlobalLoopInterval
• Want visibility:
  • Run /ss.info to view effective scheduling values (especially when AutoTune is enabled)

If you share a server profile (pop + automation level + CPU), you can dial AutoTune bias and population values for best results.
