So, I tried smoothly assigning bones with Blender for some shoes (usually it's hair, I followed a tutorial but basically with shoes and masked select where the bones go). Here's a link to a tutorial https://youtu.be/wL2v7MjaM3M?si=-tIPswjdCkfbPN9q
Tho once I tried re-assigning the WSO the l_foot bone got to the right foot. (see image, left). Even tho the original didn't look like that (see image, right). Is there something I did wrong?
