I placed one in between in my headturn (RP1 and RP2), checked the back and forth choice in the cyclelayer behavior and when I'm looking to the right it works, but when I'm turning my head back the cyclelayer starts again with RP1 and RP2 and does not going backwards from RP2 to RP1.
I'm working with Version 1.5, maybe it was a bug?
I found something out: When I'm using a key, it works like it should: RP1, RP2 and after release RP2, RP1. Hmm..
Sometimes behaviors don't get along well together. I think this might be a conflict between the head turner and cycle layers, which is why making it just a key is okay. This is an example of someone doing the cycle layers head turn that might help too: https://youtu.be/thDlCEuLzuY?t=352.
There was another curious problem with the cycle layers: I've inserted a third in-between in the right profile layer and suddenly one of the in-betweens doesn't show up. So I renamed everythring in photoshop, renewed every cycle layer and trigger. Didn't work. I've thrown all the layers away in photoshop and replaced them with different layers. That was looking good. So I copied the old ones back into photoshop and now the right profil worked fine BUT now the right quarter didn't work. I repeated the steps and now everything is fine. That is an annoying problem because there is no logic behind it
But my character now finally is ready and I'm excited to try it out!
