Hi Affinity people. I have a question regarding exporting! I am creating product images and have a file that consists of a background image with the designs in the above layer. When I export, I want the product background image to always be constant, with the design to change for each export. When I create slices it just takes the current layer obviously. Is there a way to include the underneath layers in every export? Hope this makes sense! Cheers!
