Vector characters are pretty new to CA5 so there aren't a lot of resources/videos yet showing the full creation process.
If you download the resources in your Reallusion Account for how to make vector characters and just choose one of the preferred vector editors that your most familiar with (if none then start with Inkscape or Photopea which are both free).
I've just published a blog post (first of a series) showing some
behind the scenes of my process using Inkscape. My blog contains a lot of tips for using Cartoon Animator so feel free to browse.
