I am now simply sure of if you get animate 2, almost what you want can in animate 2 timeline and aniblock,,.
about figure pozing animation, about figure morph animation.
if you made and save your aniblocks , it can change spead, it can divide , it can adjust the frame, mirroer,, etc,,,
in edit mode,, you can simply remove the parameter and remain which you want only. of course you can adjust each parameter,
(node rotation, each morph,,) on each keyframe too.
when apply aniblock as subtrack,
it can choose option, only apply or overwrite maintrack, and you can choose which node affect main track genesis.
a few days ago, I had not understand animate 2 timeline, and sub track usage,, but I now understand about subtrack setting,,
of course,, if use with pupettier, it is amazing for me,,,
I need to say thanks much go-figure,, @@; and hope more simple ani-blocks for genesis expression, or run and move.
(of course if you know about pozing and animation, you can make aniblocks so easy, and mix them free and reuse
about many scene,, I feel,, )
I recommend much,, if you try to make animation in ds 4.5, get animate 2 @@;
