The limbs don't bend correctly / don't have their full range of movement.

Hi, my team are building a puppet that has multiple views (Front, Left and Right for the Walk behaviour) and an extra rig pose that isn't tied to one of the puppet views but has the character in a kneeling pose, which will set to a trigger.

 

We're having an issue where when we test the camera body tracking and raise our arm all the way up, for example, the arm's maximum movement would hit at elbow level or where it becomes horizontal. Similarly with the legs, when we lift our foot in the camera, the puppet's foot will barely lift off the ground and only slightly bend.

Unfortunately these puppets are being made for a client so I can't share screenshots of the puppet itself or the Ch file, but here's some screenshots at least of the layer structure and our Limb IK settings.

Really appreciate any help, thank you!

The arm range-of-motion issue ended up being very easy to solve.

Your puppet's Body Behavior strength was set to 80%. You need to increase this.

 

Here is a GIF (full-res video in the attachment) simulating the issue and the solution with Hopscotch, for those who stumble into the same issue in the future:

Hi,

Thanks for posting with as much information as you can provide. The only thing I can tell from the screenshots is having multiple Limb IKs can work, but is tricky. The problem sounds like the body behavior struggling to find the intended positioning because it is finding body tags at anatomically-incorrect locations.

Would you be OK DMing me the link to your puppet?

Thank you very much for your reply. I've just replied to your DM! We're suspecting our issues lie in head / body tags and indepedence layers.. but not really sure where we should be looking. Appreciate your help!
