Hey Callum,
Thanks a lot for your reply and welcome greetings
I have made a test with new documents, and I could export them with no problem. Layers are present! So far so good. That intrigued me, and I have "investigated" the problematic file. I have found the problem by eliminating shapes from the composition until I got a successful export with no errors.
The faulty shape is a kind of "fake" 3D effect, as seen in the Youtube tutorial 3D Affinity Designer Text Effect which I have used as a source of technical inspiration. I am attaching the file with the shape that Affinity Designer could not export correctly.
The converted to curves font made a shape with an abnormal(?) amount of anchor points. I suppose that translating so many points into PSD layers caused the error.
Having the source of trouble, how to avoid so many anchor points when multiple objects are flattened/joined together with "ADD" function?
Eventually, how to make a 3D text in Affinity Designer with no tech problems that follow?
Thanks!
Roy
