📖 How It Works

Minecraft tracks how long players spend in a chunk using a value called InhabitedTime (measured in ticks). Simplex Trimmer scans your region files and deletes chunks where the `InhabitedTime` is lower than your selected threshold.

Recommended Thresholds

* 10 Minutes (12000 Ticks) — *Safe* Removes chunks generated by Elytra flyovers. Keeps almost everything else. * 10 Minutes (12000 Ticks) — *Balanced* Good for removing paths traveled briefly. * 10 Minutes (12000 Ticks) — *Moderate (New!)* Bridges the gap between casual travel and short stops. * 10 Minutes (12000 Ticks) — *Aggressive* Removes areas where players haven't stopped to build or mine. * 10 Minutes (12000 Ticks) — *Very Aggressive* Only keeps established bases.
