I don't know how to use "After Physical Properties"

[k_oshiro]

I have tried the new features of the beta version.
As for before and after IK, the official video showed me how to use it.
It is a great feature.

However
 Leader/Follower behavior feature
I don't know how to use "After Physical Properties".
When is it used?
Do you have a sample puppet that uses it?
Is there a tutorial video on it?

I am worried that it will come across well because I translated the Japanese.

Thank You.

Does the documentation on this page help?

Thank you for your response.
I have seen that page.
I made my own puppet and experimented with it.

(1) I put a primary tag on an elephant's nose with a dangle on it.
(2) I put a secondary tag on an apple with physical properties.

Is this the correct way to understand 'after physical properties'?

I would be glad to get your advice.
Thanks.

That’s a nice demonstration of how you have to use After Physics if you want dangling handle to be a Leader for a Following object.

For (1) Before IK vs. (2) After IK you are choosing whether (1) the Followers are moved first and then Limb IK constrains movement based on limb lengths, versus (2) if you want the _result_ of the Limb IK limitation to be what the Followers follow.

For example let's say you have a Wrist-tagged handle also tagged as Leader and Draggable, and an independent apple set to Follower. With Leader/Follower set to Before IK, the apple will follow where the mouse has tried to drag the wrist, even if it's way beyond the arm's length. The wrist's position is limited by the length of the arm. Set to After IK, the apple will follow the same position as the wrist because Limb IK has already constrained the position of the Leader.

Appreciate your advice.
I also think it is a great behavior.
It makes what used to be a difficult task easier.

and Thank you development staff.
