First of all thank you for the great tool!
I would like my customers to choose and customize the products from front, where the image in the background will be their photograph and the layer on that will be snapshot of the video (product variation image).
However, when they order the product, I intend to print only the image in the background to be printed automatically in the PDF. Somehow, I am not sure how shall I remove the layer of video (front) for that purpose. Can you let me know how I can achieve it.
Is that being sent along at all? If it is then yes I'd say you should remove it before creating the output image.
