Alright, so I would like to create a rocky roof, I know i need to use displacements. I go, make a brush, choose the bottom (and only the bottom) face. create a power 2 displacement. use a little bit of paint geomerty magic (though I did test it without doing this), go to compile the map and... it won't load up. I go to the console do the Map [mapname] and it says it cannot load the map because of an error or invalid displacement... -No leaks (checked twice) -Ran through interlopers, only error i'm getting is that i'm running fast. vvis (tried on normal, no change) So yea, what am I doing wrong?
