Hello!
I got to the mesh skinning portion of the piero tutorial. Is there an obvious step I’m missing with the feathers? Only the most recent one that I parented to the armature will deform.
The steps I’m following, as in the tutorial, are : select all bones, deform to off. Select desired bones, deform to on. Parent the current feather to the whole armature. Repeat for next feather.
Note below, how the two inner feathers won’t move at all. However, they are set up the same way as the one that is moving.

Could someone let me know if they find a solution? Thanks for reading!
