a big circle red D: ...

when I open my hammer and edit a map I get this gigantic red circle



I worry that my map is affected by this, last night I did not have a limit to see everything

 

This is radius culling. Toggle it with C or by pressing
anything outside this circle will be excluded from the compile, leading to many leaks occuring if people don't know what it is

 

Thats radius culling, click on the button with an R inside of a red circle up on the top toolbar to turn it off.

edit: damn i got ninjad.

 

Thanks very much
