Compare circular and square Chunky selections for the same playable area

Applies to: Chunky; match the linked maintainer documentation to your installed platform and release.
Documentation checked .

A circular border and a square selection with the same radius cover different terrain. Choosing by radius alone can generate unnecessary corners or leave intended areas uncovered. Sketch the playable footprint before deciding which Chunky shape should match it.

Work through the change

  1. Record the world, centre and boundary shape used for ordinary players. Include any border wrapping or portal exits that can place players near the edge.
  2. Read the installed Chunky shape and radius controls. Prepare a circle selection and inspect it with chunky selection, then record the corresponding square selection without starting either job.
  3. Compare both footprints against several known coordinates: the cardinal edges and the square’s corners. Use the footprint that matches actual access rather than the one with the more attractive initial ETA.
  4. Run a small trial of the selected shape during a quiet period. Check chunk growth, free disk space and normal player response before committing to the larger radius.

Check the result

The accepted selection should cover the reachable play area without an unexplained mismatch at its corners. Generated area grows roughly with the square of radius, so a small radius increase can still have a large disk cost. Keep the precise shape in the maintenance record.

Border shape and pregeneration shape need separate records even when they match today. A later border change can expose terrain beyond the prepared area unless someone compares the updated footprint deliberately.

Recover or stop safely

Pause a running job before changing the plan. Existing terrain outside the new footprint remains part of the world and may contain player activity. Preserve it unless a separate, backed-up trimming procedure has been authorised. Restore the previous border policy if access was altered only for testing.

For the broader setup, read Pre-generate Minecraft terrain with Chunky and monitor disk space. Check the installed plugin version before applying syntax from the official Chunky documentation.
