Help! Elbow / Knee Rig snapping/locking (right side problem)

[danielblaze]

Hi, I'm trying to create a stretchy IK leg with knee snapping/Locking. I managed to create the IK stretching on both the sides, however when i'm doing the knee snapping on the right side, the joints first squash and then they flip.

Why is this happening and how do I fix this please?

screenshots attached.

Your help is very much appreciated.

Thanks

Daniel

Hi @danielblaze

Does this only happen with the right side?

If so it may be because the ankle orientation is different than the left. If you look at your third screenshot the right ankle gizmo is pointing its X, Y and Z coordinates in the wrong direction compared to the rest of the joints. Then in your other screenshot when you get the issue the orientation is fixed and facing the right way.

So I would recommend you try redoing/fixing that joint and see if anything changes!

What I actually ended up doing is using a multiplyDivide node to invert the values to negative on the right side and it worked fine 🙂

Thanks anyway.
