I notice while using the tumble fly effect in the overlay that the object can only be seen during the front part of the tumble. I'm using chroma key over a timeline background. Did I miss something in the instructions or is this just the nature of the beast? I'm using Videowave 11
I've got a partial solve. I put two of the same image but one flipped horizontally on their own overlay track. while in still mode I rotate the flipped image 180 degrees and 180 for the Y rotate. Then I switch it to tumble and that seems to work fairly well.
