Hi there, I'm working with a document currently that has several embedded .afdesign files (as they were created in Affinity originally). However, when I export the document, all these elements are rasterised and become ugly. This is an issue as I'd like to be able to have one logo which I make tweaks to, embedded in some mockups. Is there a way around this? I really like the way embedding is implemented other than this. Cheers, D
