Hi folks,
I have been following houdini rig fur dude tutorial series. On this episode " https://www.youtube.com/watch?v=qCBQUilJVg8&list=PLXNFA1EysfYl8k8tEcjknN66L0jqbixMB&index=12 [www.youtube.com] " at around 2:21 he uses skeleton blend. I have done exact same step but mine deforms weirdly, any ideas how to solve this ?

Really appreciate your help.

Can you post your hip file? Just looking at the image, it looks your joints in the right input of the skeleton blend are wrong.

here is the hip file edward.

Maybe there's a bug in the 19.5 version that you're using that has since been fixed. I only have 20.5.410 (macOS) on this machine and the problem doesn't reproduce for me.
