Hi All, Thanks so much for sharing this with us - it's a great technique! I wanted to mention that you can also adjust the paint stroke radii simultaneously (without using expressions/coding) by making the strokes share a single brush node. You can then using the global scale slider on the stroke's brush node in the Attribute editor. This option is found under Paint Effects>Share One brush. I did a quick screen capture here: https://youtu.be/xeK-e8tqRIw Thanks again for all the great resources! Cheers Simon PS wasn't sure if it is OK to link to youtube from here so apologies if it's not!
