Bumping this again, since I was searching for this, too. My question is, can I animate the visibility of a bone and all it's children?
In our case, we are doing some canned movie-like sequences where multiple characters are interacting in one big Spine animation. We need one of the characters to appear half way through the animation, but so far the only way to do this is to animate every attachment under that character's top bone.
(Same problem with color and transparency, actually - can't do it to a bone and all it's children.)
Any chance this ability will ever come to Spine?
