Found Why I Couldn't Export/Import .psd for Bone Hands
I attended June 2022 Webinar for Cartoon Animator 4 and asked a question about how to Export/Import .psd for Bone Hands. I've since discovered that because I had the pipeline set to Adobe Creative Cloud Photoshop instead of the Photoshop app on my computer, that the pipeline didn't work. I've since updated the path in Preferences, and it works great.
