Maybe I’m just missing something, but I don’t think the newsletter says you need to set the layer one compositing mode (not the parent/child compostiting mode) to Multiply (mask) in order for it to work. Maybe that’s just with newer versions of vegas (than when the newsletter was written), but you have to do this or it won’t work. At first I was getting really frustrated, because I was doing everything it said, but not getting anything other than the white mask. Then I figured it out.
Not complaining, just letting people know, in case someone else trys this.
