Actually, that's how I did the last round of sealing on the space: with the door open, any drafty spots revealed themselves. All those blocked-in cavities became very still and quiet where the foam did its job. Just a small pressure difference in the structure made obvious breezes flow through spots that needed to be sealed. I didn't need to use smoke or anything.
I was on the fence about taping up the seams where I cut sections of the rmax board to fill some wall sections. After the spray foam operation, the same effect can be observed, even in some places where the pieces seem to fit well. IMHO, it would be stupid not to tape all of these seams before covering them up.
