No, the gold splatters is not vector and I know it. That isn't the problem. The missing linked files aren't missing, I just forget to upload them to the drive, where you found the file. I tried every pdf output, but none of them worked. I made the logo in Designer and the business card in Publisher. The logo looks like as a vector, but when I saved it, then it rasterized. In the beginning, I didn't think that the brush strokes are the problem. Now I seached more and I found the post, what you mentioned: "Currently Affinity Designer doesn't support "pure" vector brushes and by this i mean brushes composed by vector objects rather than images. ... We do have plans to improve the vector brush engine to include/support true vector based brushes later."

This is the first page: card

I made experiments and I think I found the problem - I drawed the stars and the brush with curves in Designer. But after that I changed the strokes - I used one of the Brushes. On my computer they looks like vectors, but when I save them, they are rasterised. Is this the problem?

I did it, but it still rasterised. I tried out what will happen if I erase every layers expect the stars and the brush. I saved it in pdf again - they are rasterised.

I made some business cards in Publisher, but when I want to save them in pdf, the vectors always rasterized. I tried lots of different adjustments, the "Allow advanced features" was selected on export, and I tried to use old Publisher versions, but none of them worked. What else can I do? Or this is a bug?
