Hi, thank you - that is exactly what I'm looking for. Unfortunately it turns out there's another version of Affinity I didn't know existed, so I can't open the file you sent. I'm not sure I entirely understand what you mean either, sorry!
I have been drawing a rectangle and an oval shape on a transparent background, using the Xor tool to remove the oval, then applying the gradient to the remaining rectangle-with-an-oval-missing-in-the-middle. I'm still getting a weird linear gradient on the rectangle. The other versions of gradients (elliptical, conical etc) don't look any better either.
Is it an I'm using an old version issue, or is it an I'm not choosing the right options issue?
Thank you for your patience - I know this software could do an awful lot more for me if only I had any idea how to use it.
