  What to do!?

  Posted by Martin Hansen on July 24, 2008 at 8:58 pm

  Hi I have a question.
  In my video i am receiving gun fire from another person on side view. I put bullet holes with dust on the wall beside me. BUT when my arm/body steps in front of the existing bullet on the wall the hole is on top of my body. Please tell me how to get the bullet hole to be behind my body.

  Thanks alot

  Let’s say you have two layers: the person layer and the bullet layer. You need to duplicate the person layer, put it above the bullet layer, then shut of the eyeball switch for the top person layer. Draw a mask around the arm, or whatever it is that overlaps the bullethole. Animate the mask shape so that it follows the arm over time. Turn the eyeball switch back on. The masked portion of the top person layer should obscure the bullethole whenever the arm moves in front of it. You might want to adjust the feathering and expansion of the mask to get a cleaner and softer mask.
