I made this video to show you a little R&D I did last week.
the idea is to make a tool to brush any Splines as if they were hairs.
for the moment it only works on a 2D scenario, but I plan to convert that in a more 3D environment to add it into the next version of my FurGuides Painter. And eventually release it as a separate tool as well.
let me know if you are interested in this tool, if you have any ideas or questions
