Hello guys,
I´m having a bit of a problem here and would be glad about any clues. I set up a scene in the motion tracker to add some visual effects to it. Then I masked a foreground object in the image sequence. Now I need to do an additional rendering with only the effect with alpha for external compositing.
I just can´t get the mask get rendered as alpha aswell. The mask shows up black in the rendered image (not the desired checker-pattern).
Is there a way to have the mask rendered with alpha?
Thank you for your help!
