I was following Blender Guru's Abandoned House tutorial. At 2:45 of the video/ my project I had to shrink/fatten the house up because of some mesh problems as instructed in the video. I was doing that but the problem was that the wooden panels extrude out of the house...the Boolean modifier was already turned on before the shrink/fatten and it worked fine....but it doesnt work after the shrink/fatten...how do i get it to work ?
