I have two white shapes that overlap on a purple background, which are in a pre-comp. One in animated (an arm) and the other is not (the rest of the body).
When I fade the pre-comp in, from 0 to 100 opacity, I can see the parts where the shape overlaps. This is made worse by having a motion blur, which seems to multiply the blur in that area.
Do you know how to avoid this situation, and to have the two shapes behave as one.
