How do you tame a ChainIK ?

[laurentlavigne]

ChainIk is what the doctor ordered. Problem is, unlike its 2Bone sibling, it doesn’t keep the initial plane of rotation and instead gives me this

So, without a pole vector, how do you tame chainIK?

Hi!

The ChainIK constraint implementation in Animation Rigging is based on the FABRIK constraint. It works well in runtime applications when applying to a pose that is already set in a configuration that is close to what you target (e.g. look at our sample scorpion tail that is slightly bent already so that it retains this shape in runtime).

If you want more control on the chain IK constraint, then you can implement your own constraint in Animation Rigging. We’ve shared a lot of resources to help with that in the past few years:

Compilation of resources for Animation Rigging

Hi, Seeing as these questions come up often in this forum, here is a compilation of resources that are available to help learn about Animation Rigging. We'll update this thread as more resources become available. I'm hoping this is useful to everybody Manual: https://docs.unity3d.com/Packages/com.unity.animation.rigging@latest/index.html Samples: [5624815--583540--image8-1.jpg] Talks: Introducing the New Animation Rigging Features (GDC 2019): https://www.gdcvault.com/play/1026151…

I don’t have the time to roll out my IK with everything else to do so is there a multi bone IK that behaves like a 2 bone ik? with pole vector to define plane
