displacement on polygon house
the prob is that i want to add some cracks to a house with a displacement maps on polygons...i dunno where i do things wrong. the disp. map is all white black and grey...i blurred the map in photoshop.when i aplyed it to the house i used approximation editor and set it to highest quality.The geometry is 1 peace....and even doing all that gave me the effect of each wall going in its own way in space when rendered....the walls are completely detached
Give an advice!!!
emergency!!!
