*For The Draw Persona*
Recently, I've seen my friend use a program that has a feature called force fade. The pen/brush tool will fade at the ends a certain percent depending on a small meter. I've been looking around the app on my mac, but I could only find size variance which depends on the speed/velocity of the user's stroke for the vector brush. I couldn't find anything that would fade the end of the line I'd made with the pen tool. I don't have any images at the moment, but I could get some screenshots from my friend as an example.
Thanks for reading!
