ok, I had this error before but i managed to fix it with _blocksize then some numbers. But I got it again even with that after i added a room to one of my main huge rooms. I tried adding fog to main room cause i heard that may stop this error but it didnt for me. so then I thought forget the room and i deleted it but still got same error. I tried messing around with the numbers using 6000 then lower ones. Now im stuck. I have read previous posts but they don't seem to help me. What i think might work is detailed brushes but every time i click on an object then click to make it detailed it disappears! I dont know where it goes it just vanishes. At first it thought it was there, just radiant going nuts but i got leaks in those spots... If someone can tell me how to fix visibility error or make detailed brushes show up i would appreciate it!!:bows:
In Radiant go to View-->Filter and see if Details is checked.
for some reason it was checked and now i can see detailed objects but i tried to make many things detailed and it didnt help i still get that error.
