Landscape freezes

ok i have a question i have searched the forums and still nothing. so here is the issue i load up the map and everything seems OK…there is already 4 lvls on it a persistent one the landscape and a near and far i have most of it already formed for the area i want to start with but when i try to do touch ups i click the landscape it freezes for a few about a min then it will switch over but there is no brush just a cross hair when i try to click then it freezes for good i left it sitting for about 2 hrs to see if it would move on with no luck. any ideas?

Do you have more then one landscape? What size? It could be that you are running out of RAM. I’ve noticed similar issues and it gets worse the larger the map and the more stuff you have on it.

i only have one landscape and its maxed out 255x255
