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

Question

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.
