Hi Nate!
I figured it out thanks to yours and Soren's "Spine Artist Workshop" video on YouTube. I had to add more images to the slot so it could switch from one arm to the other for it can only display one image at a time in that slot.
I have not animate the eyes and arms yet but I think I got it. The little ninja run video was very helpful and opened up the doors to animate more and more for I thought this was very limited type software but I realize with a bit of work we can animate something that looks really good.
I am a classic 2D animator for almost 30 years and working on a software is a very hard transition but I'm starting to enjoy it. There are still a lot to learn and I'm looking forward to test my animation abilities on Spine.
Cheers
Edison
