I'm sorry I am not explain correctly my point of view.
In a 2d software “onion skin” is very handy in Houdini too.
The problem is when I use it I never found any way to freeze the “onion skin” pose during animation…
Let's think if I use Bea(female's Houdini character) and active onion skin I can go to misc tab and press D to set some configuration.
But the configuration not give to me any option to “freeze or bake” the specific pose to use like a reference that can help me.
Some thing like this below:
It is near what I thought but it will be more useful if we can have control to put the pose static may a “node” to do it
Any way now I'm studying character animation a lot and try to transfer all knowledge to Houdini.
Sorry to take this converstation to long but I think in a few time a lot of character animators will come to Houdini.
I'm use Houdini Indie this is a great tool to start our way.
