Hi there - I'm looking for some advice on best practice document scale when using textured vector brushes or raster brushes in Affinity Designer.
I've just started to use some new brushes which were recommended in Spotlight here on Affinity. https://affinityspotlight.com/article/grave-etcher-vector-engraving-brushes-by-retrosupply-co/
They are great brushes but I'm a bit stumped as to how much I should scale up to preserve crispness in the final illustration as when I zoom in, the vector brushes are not true vectors, they behave like vectors (editable) but rely on raster images for the effects. This is explained in the suppliers own FAQs here https://support.retrosupply.co/article/81-why-are-my-affinity-designer-vector-texture-brushes-pixelated-when-i-zoom-in but they give no advice on how to avoid pixilation.
I've emailed them, but thought this was actually a wider issue that some of you would have come across with raster brushes etc.
So for example, if my end illustration will be printed at 5" x 5" . would setting up my original document at 15" x 15" at 300dpi be sufficient to avoid pixilation or should I just experiment. Is there an idiot proof formula? I don't want to go down a rabbit hole and find out I'm back to square one at the end of the process.
Thanks in advance.
