Thank you for your response! 🙂
I want to say that I've used this feature successfully in the past, now it seems size variance and opacity just don't work anymore on either of my computers. I've tried pen tool and pencil tool for vector drawing. I noticed the original basic brushes have disappeared. I've rebooted. Closed the app and restarted.
In Designer Persona.
I am using a pen and tried editing existing and custom brushes.
When I use any brush and attempt to change the settings so that the ends are thinner but as you can see, they are still just as thick on the ends. I expect it to correspond to the line I've drawn. Nothing is happening to the line I'm attempting to apply it to. I would expect the brush edits to work in existing brushes and new brushes.
No error messages.
I'm using a mouse so I understand I need to be in velocity and not pressure. I've now tried both.
For New Brush: Brush Width works. Size Variance doesn't work. Body, Corners, Head Offset, and Tail Offset are all greyed out.
For Existing Brush: Brush Width works. Size variance doesn't work. Body, Corners, Head Offset, and Tail Offset are editable but won't apply.
Here are screenshots to help tell the story.
