NewChunks
NewChunks highlights chunks that were freshly generated by the server rather than loaded from existing saved data. When a server generates a brand-new chunk for the first time, it often contains flowing fluids (water or lava not yet settled into source blocks) — NewChunks uses this signal to distinguish newly created terrain from old, previously visited chunks. New chunks are overlaid with one color and old (already-existing) chunks with another, giving you a clear picture of where the world has been freshly generated around you.
This is particularly useful on anarchy or exploration servers where finding untouched terrain matters — for example, when searching for pristine structures, stash locations, or areas no other player has visited. The overlay is drawn as a flat colored plane across each chunk at a configurable Y level, making it easy to read at a glance without cluttering the normal game view.
With Persist enabled, chunk classifications are kept even after the server unloads them from your view, so your map of new versus old chunks builds up over your entire session. The Smooth option blends the colors of old chunks that border new ones, softening the boundary between the two and making the overall overlay easier to read.

Settings
| Setting | Type | Default | Range | Description |
|---|---|---|---|---|
| RenderDistance | Integer | 32 | 4–128 chunks | How far from the player (in chunks) the overlay is drawn. Chunks beyond this distance are skipped. |
| RenderY | Decimal | 0.0 | -64.0–320.0 | The Y coordinate at which the chunk overlay plane is rendered. Has no effect when AutoY is enabled. |
| AutoY | Toggle | false | — | When enabled, automatically places the overlay plane 100 blocks below your current Y position, keeping it out of your immediate line of sight. |
| Smooth | Toggle | true | — | Blends the color of old chunks that are adjacent to new chunks, creating a smooth color gradient at the boundary between new and old terrain. |
| Persist | Toggle | true | — | When enabled, a chunk's classification is remembered even after it is unloaded from your view. Disable to remove a chunk's overlay as soon as the server unloads it. |
| NewColor | Color | — | — | The overlay color used for chunks identified as newly generated. |
| OldColor | Color | — | — | The overlay color used for chunks identified as pre-existing (old). |
