Hi guys~!
I have an arm skeleton undergoing hand movement testing.
I placed father son restraints on the radius and hands.
When the character's hip bone is stationary, the hand rotates and the radius can follow the rotation, everything is fine.
But when hip exercises, there is a problem with my radius constraint.
May I ask how to set it so that the character's hip can move and the arm radius can also follow the hand correctly
Thank you!

Hi,
In order for the constraint to update properly, you have to give it some additional information.
I have made some adjustments to your scene, hope this helps.

ps. I have included a apex scene that does the same thing.

Great, everything is so perfect!
You are so thoughtful, even the APEX version has provided a solution, I am so happy~!
Wishing you a smooth work experience!

Hello William
The attachment files you provided all reported errors when opened with houdini 20.5 and houdini 20.0.5.
After clicking 'OK', a new error keeps popping up. Is it because I am missing some component?
The last time I tested the file, I thought it was a version issue, but now I am using 20.5 and still getting an error.

May I ask how to achieve the APEX effect in Houdini 20.0.5 ？
Sorry to trouble you again, thank you very much~~!

I think your 20.5.278 version was still too old. Will's file was saved in 20.5.400.

Thanks for your reply
Then I'll just use the new version directly
