How I can I make smoke and fire look like it coming from behind a building or through a window?

            Masking lets you block out portions of the added effects so that you can make the effects look like they are coming from behind structures, through windows, or otherwise blocked by other elements in the scene. For example, if there is a lamppost directly in front of you (and on the background image), you can mask out any smoke you put on the picture in the area of the lamppost. Then the smoke that is “behind” the lamppost will be blocked out, making it appear that the lamppost is in front of the smoke. Watch this video to see how to mask the roof line, to make smoke look like it is coming from the roof or from the opposite side of the building.
