Arm IK stretchiness controls stop working within a swap set of arms.

I have a puppet with arms with swap sets. I found this works better for arms with various hand gestures as hands in their own folder move with the arm but can be floppy and hard to control. Problem is with arm IK enabled I can limit stretchiness. But with the swap set it does not work. Placing arm IK on each variant doesn't work either. Is there a workaround or is there a way to make hands in a swap set in their own folder stay rigid when they move with the arm when it is dragged? Thanks.

If you're using Arm IK, it sounds like you're using an older version, as the behavior changed name to be Limb IK in more recent versions. So first I'd recommend updating.

 

You should be able to either apply Limb IK to each group (for independent parameter control), or, if you want identical parameters for all triggered groups, you could apply Limb IK once at the root and make sure each arm group has a view tag like (like Frontal — you can apply the same view tag for all of them). Limb IK will then treat each view as a separate grouping of limb tags.

 

Sounds like you already tried applying Arm IK to each group, so maybe there's something else confusing it. If upgrading and/or the view thing doesn't help, sharing a hierarchy screenshot (or the puppet itself) could help us diagnose.

Thanks for your response. I am on the current version I just choose 'arms' rather than both arms and legs. I'll get back to this I have a more serious issue wherein a walk cycle malfucntions and the arms movedown, I'm posting seprately about that as to not be confusing since that wasn't the topic here. Presently I stripped the rig down so the other issue is moot for a while. Thanks.

Oh should mention the shoulder tag is on the body, the elbow and wrist are on the arm, which is working fine with movement and such. Tagging the shoulder on the arm as well had no effect, thanks.


Instead of separate handles for Right Wrist and Draggable, have you tried having a single handle that is tagged with both?

If that doesn't work, and you're willing to DM me with a link to the .puppet file, we'll take a look here at the factory.
