How do I create a mockup from my book cover?
First create a front-cover render by clicking Remake Cover on the cover customization page. Mockups use that completed render rather than the unsaved editor preview.
Open Mockups from the cover page or your dashboard, select the front render you want to use, browse the mockup library, and choose a template. Adjust the cover placement and any available colors or layers, then click Generate Mockup.
