Hello,

I'm following the Rigging Series and I stuck in the left arm part. when adding the ik with twist it doesn't work with the constraints network. I checked if the bones are straight, because the ik works without the constraints and the constraints without the ik solver.

I did excatly the same as. Mr. Goldfarb in the tutorial with the blendconstraints-node and so on.

is there any change from H16.5 to H17?

thank you

we found an issue with constraints just before the Holidays and it was fixed around Dec10 - try the latest build of Houdini - at the moment that is Houdini 17.0.451
