How to Fix IK Flipping Issues

BinaryCats · Oct 7, 2015

Single bone IK's do not get resolved correctly

In order to fix the flipping you need to add a dummy parent bone to the bone you want to IK, Then create an IK manipulating those two bones (dummy parent, and bone you want to IK)

Here pink has one bone which is IK, and Green has two bones which behaves like a one bone IK

And when flipped you can see green is still correct

Spine v3 will handle flipping differently which will make it somewhat simpler to work with when doing flipping.

Basically the flipX/Y property is gone and instead flipping will be done by scaling negatively. IK even works with non-uniform scaling in most cases. There are some caveats but I'll let Nate explain that in detail once we release v3.

It seems like we have been waiting for a while for v3 and likely we will have to wait atleast another month.

Seen as people have been pming me about the issue. Thought I would make a clear post
