Several things look different from the video:
1. Call the top level +Max (add a plus).
2. Drag the Head and Body into +Max, currently they're outside.
3. Delete the background layer.
I've been trying all sorts of combinations... but keep getting the same thing... the eye is interacting with the movement of my eyeball!
I tried adding + and making the RP and RE warp Independent... but that has worked either!?
I want to get this simple animation working so I can understand the basic of Ch, before I move on and start adding more... if that makes sense!?
The reason that is happening is because you don't have a right blink layer in there. You either need that or set Face > Eyelid strength to 0%.
That's done it... as soon as I added the Blink layer... if became stable. I tried turning the Tag for Blink of and on.. to test and that's the answer!
The Eye Group then needs all three layers for the Eye to function correctly!? Blink, Eyeball/Pupil Range and Pupil
Does this apply to other groups of Tags?
Well it's Friday, so I'll leave you in peace over the weekend! Have a good one!
For all eye functionality, yes. But we try to accommodate all eye types. For example, several of my characters just have pupils.
I'd say the eyes and mouth are the trickiest and most complex parts. If it's helpful, i've added some links to a simple blank PSD template and simple Head PSD template below our puppets on the examples page.
