I just realized Serif DrawPlus 8 is a legacy product being replaced by Affinity. DrawPlus is now $24.99, and Affinity just $49.99. I was about to buy DrawPlus for creating characters in CTA3 and wondering if I'd be just as happy with that. The price is certainly right.
As it stands, DrawPlus 8 is not only the better option it also has more features relevant to exporting your art to CTA3. Affinity Designer has no animation tools and cannot export vector art as .swf files (i.e. flash file format). .swf is the format you need if you want to create G2 flash based characters or simply prefer using resolution independent vector based art over .PNG raster based art.
I have and use Affinity Photo but won't be upgrading to Affinity Designer because of the lack of animation tools and .swf file export. It may introduce support for at least .swf export in the future since, I'm sure, DrawPlus users upgrading to Designer will be missing flash file support but for right now, DrawPlus X8 is the better option.
However, for anyone who has DrawPlus and needs to bring their clipart into Affinity Designer for whatever reason, gcshep's tutorial is worth a look.
