My reactor makes portals [SOLVED]

[MothMan]

Hi community ! This is my first post in this forum.

I'm currently making a train map for me and my friends, but I have a problem with some vis portals.
I attached an image to show you that the reactor generates 4 portals I don't want to have.

Do you know how I can remove them ?

Thanks in advance.

Those are not created by the reactor, they are on coords x=0 and y=0. By default the whole map area is split by portals at 1024gu intervals, use the _blocksize key on worldspawn to change it if you really need to (value 0 to disable it iirc).

Wow great ! Thank you a lot ! I was near to suicide because of this.
