I'm using t Affinity Photo to 'pipeline' to and from. I'm finding that when I do this , say to alter the colour of the 'hip clothes', when I save and go back into CA the hip has changed as expected but i've lost the eye and mouth sprites? The only change to the pipelined file in Affinity Photo is to the hip. nothing else is altered. The file when pipelined into Affinity Photo contains the eye and moth sprites.
I tried the link option here and it did not work in the current versions of Affinity Designer and CA4. They have told me a hotfix will be ready by the end of the month.... That's a month's work lost... They are more interested in selling more stuff from the store than fixing issues for existing paid users.
