Whats the max brush limit for a map? Anyone know? That is for JA..

Don't think there is one...per se.

HEHE! This is good news.... lol, my next question is would it be a problem if i made a 20000 brush map? If so then for what reasons? Supposing i used proper vis blocking i figure i could get it to run quite well on a medium to high end machine... that is if vis blocking is effective? Is it safe to say that a 10k brush map with 8000 brushes not being drawn will play like a 2000 brush map? If so then it shouldn't be a problem right?

well.. theres only one way to find out.. compile.. and run it. Then send it to people to test it... so they can check there FPS.

Maximum of 32,768 brushes by the compiler. The amount of brushes doesn't matter so much as is how many surfaces are drawn at once.
