One of the main things I was thinking of doing to improve the Art Brush tool was to give it the ability to add vertices to the brushstroke. That would mean it could more easily follow the paths the user defined without requiring the manual addition of vertices to the brush symbol. Well, it turned out to be pretty easy, and I implemented it yesterday and today. So as of now, the Add Vertices tool is no longer necessary. I’d encourage anyone who downloaded the Art Brush tool before Wednesday April 7th to re-download it. It’ll be a significantly friendlier tool to use, and no more will you have to think about whether your brush symbol has enough vertices to follow your complex path.
For convenience, here’s the download link again:
