# Why aren’t controllers auto-rotating?
TLDR: It’s gone. But hose parenting has increased accuracy and renders faster. You can still parent a layer to a controller, but it will not auto-rotate.
Context: Rubberhose 2 introduced the concept of controller rotation to the world of rigging, and it revolutionized how hands and feet attached to limbs. It was a cool feature, but required a lot of redundant math to allow controllers to define a curve, then the curve defined the controller rotation.
# Where is RubberPin?
It’s gone. Adobe has made a series of changes to their Puppet Pins system that improve usability in many ways. Unfortunately, it is currently very difficult to distort a layer in a Rubberhose-like way using pins.
If the Puppet tool is a part of your workflow, jump on Discord and help us make sense of how this could work with Rubberhose 3.
