Catch an off-centre Chunky selection before generating terrain

A radius does not establish where a pregeneration task is centred. An old selection can leave a new world generating around coordinates from a previous job. Read the complete selection before starting so the finished terrain covers the actual spawn and intended playable area.

Work through the change

1. Write down the target world’s exact folder name and the planned centre coordinates. Decide whether the centre follows world spawn or a fixed location agreed with the map owner.
2. Select the target world in Chunky and set the centre explicitly using the installed command syntax. Set shape and radii too; avoid treating the current defaults as evidence of the intended area.
3. Use chunky selection to read the resulting world, centre, shape and radii together. Compare the minimum and maximum footprint with the playable border and any existing distant builds.
4. Start a modest trial area first and inspect new chunk growth around the intended centre. Record the selection output before extending to the full planned radius.

Check the result

Generation should expand around the written centre and cover the intended corners or circular edge. A map preview can help, but its own rendering delay may hide recent terrain. Confirm coordinates in game and the active Chunky task status before leaving a large job unattended.

The selection readback is the approval point for the job. Save it where the next administrator can compare a running task with the original plan without reconstructing coordinates from memory.

Recover or stop safely

Pause the task if its centre is wrong. Record what has already been generated, then plan a corrected selection without deleting terrain. Cancelling progress does not remove generated chunks, and a misplaced pregeneration area is not permission to trim a live world with player builds.
