Hi,
Any ideas in how to create an FK/IK spine in houdini? without using the autorigs.

thanks,

you could start by building an Follow Curve IK spine, then blend it on/off with the blend parameter on the IK CHOP…

there is more to it than that but it's a good place to start

the attached file isn't how you would want to do this in production…but it gets the point across.
HTH

Thanks a lot!
