  embedded alpha channel

  Posted by S. Marcotte on November 28, 2007 at 9:45 pm

  Learning Keylight. The documentation says: “If more than one
  mask is required to remove garbage, then use the masks to
  create an embedded alpha channel…”

  This is from a section on Inside masks. I get the idea, but how do I go about creating an “embedded alpha channel”? Does it require a render?

  Thanks in advance – SGM
