Ah, ok, thanks KJerryK.
I noticed that I could move the puppet by shifting it in the puppet window but found it jumps back again if you make any edits to the original.
Seems kind of odd, say, if you wanted to have multiple characters and I wondered why it places the puppet in this position by default?
The upper-left corner of your artwork's canvas (in the artwork file) is the upper-left corner of the scene.
And so, if I move it in the puppet window so it now sits in the middle of the scene, should it stay there?
I seem to recall that I did this, then made some edits in PS that caused it to jump back to the top left again.
Ah, if you're using the Layer properties to move a layer in the Puppet panel, those are reset when the artwork changes. Use the Transform behavior for the puppet to position it in a scene.
