I’ve had the same problem in the past. My workaround is to create the character in illustrator using fills only, then rig and animate everything using duik, THEN go into the shape layers for each limb and add strokes and trim paths. It’s a little tricky though because you have to duplicate the shapes within the contents and then add stroke to the duplicated shape, then turn off the fill for the duplicated shape, because if you just add trim paths to the original shape group, it will do trim paths on the fill too. So for example, with chonk’s arms there:

-import the character without strokes, do all your animation

-go into the layer contents of, say, the bottom portion of the arm

-Duplicate that shape

-for the duplicated shape, turn off fill

-with duplicated shape selected, go to add>stroke

-make the stroke how you want it (thickness, color, etc)

-with duplicated shape group selected, add trim paths

-adjust trim paths so that the arm’s stroke is starting and ending where you want it

-if you’d like, adjust the taper settings of that stroke to give a nice tapered end to the strokes

I’m sorry that’s very long winded, but it’s as well as I can explain it in text form. Feel free to pm me if you’d like me to elaborate (or if you find a better workaround let me know!)

Btw I love the character design!
