How can I reverse rigdoctor?

Recommended Posts

Posted (edited)

Hi guys!

I'm new at kineFX in Houdini.

I just want to reverse parent and child of all on curve line.

I tried simply reverse the number of point with sort SOP and also reparent joints, it didn't work.

Can you guys tell me how to solve it?

KineFX uses vertex order to set hierarchy. A reverse SOP will flip the hierarchy. Make sure it's wired in before the first rig doctor. Once you add a rig doctor, additional attributes are added that define parent and child indices and local transforms are calculated using that hierarchy. Adding a reverse SOP after that won't have any effect.

Thank you so much for your detailed reply. It was a big help.
