Go into crouch when root is moved (IK)

Hello Peter,

first of all i'm totally amazed of your tool! Just bought the pro version and made use of it today.

I can finally create my own simple animations for my game:

https://store.steampowered.com/app/892510/Slay_Together/

I want to use IK to get my character into crouching by pulling the character down on the root bone. I tought that this would be enabled by default but it seems like I have to setup an IK chain manually. Is that correct?

Greets,
Jannick

Hi Jannick,

thank you very much for your support request and for your nice words. Much appreciated!

Also congrats for launching a game on steam! Looks like a lot of hard work went into this project.

What you are looking for is called IK pinning. IK pinning would pin the feet in "world-space". By default, the feet move with the hips. It's easy to set this up:


  1. Execute the IK setup wizard (please checkout the quick start video tutorial or the IK video tutorial for more information).
  2. Select both IK handles of the feet (the wire cubes) and set the "FK/IK Blend" slider to 1 (= IK) in the channels view of the pose editor. Also enable the check mark on "IK Pinning" so that the feet are locked in place.
  3. If you now move your hips, the feet stay in place.

If you want to change the IK pinning state multiple times within an animation clip, make sure to check out the following two video tutorials:

Please let me know in case you have any follow-up questions.

Best regards,
Peter
