The Post So at this point Ive got two primary renders and an additional plop of a doorway to integrate. Enter PSP. I mask the back of the barn in with the front of the barn (but not extending it out past where the front of the barn was), mask the doorway plop in, and the transition areas between the middle and background areas, going over them a little with a low density clone brush again after flattening and merging all the layers to make sure everythings smooth.
