Good day,
we have a problem with our map.
Whenever we render, there are errors on the map.
It renders further than it should.
The whole map is almost round except in one place.
We now want to remove the section that has been rendered superfluous.
Now we have the problem that we cannot exactly assign which image is intended for which position in order to remove the images precisely.
Is there a possibility to assign your picture to a position based on the exact coordinates?

Or is there another way to fix it

what you are asking is not easily possible, however, there is a workaround. you can add a circular visibilitylimit in worlds.txt:

    visibilitylimits:
      - x: -2000
        z: -1000
        r: 200
    hidestyle: air

what is stated above will render everything in range of the circle with radius of 200 and centered around x:-2000,z:-1000.
after a restart and a radiusrender in the problematic part it should be black (hidestyle: air)

where do you get the coordinates from x: -2000 z: -1000

from the default worlds.txt. most often it is the spawn if not defined during pregeneration

Looks like it is centered around spawn, look at the spawn marker, and select it's block location that is your x and z, the r is the radius

I'm acting a bit stupid right now...trying to understand what the x and z coordinates are

Looks like it is centered around spawn, look at the spawn marker, and select it's block location that is your x and z, the r is the radius

should I take the radius up to the world border marking or with the safety distance?

What you want, to the border requires many radusrenders or a fullrender, if you add the safety distance you only need to radiusrender on the extraneous parts

Thank you for the information, I'll try it now. I hope it works this time

Great it worked. looks really good again.

Thank you for the tip :)
