Godot Version 4.6.2.stable Question I’ve been at this a while now and I can’t pin down the solution. I’m working on foot ik/ground alignment. Video proof below shows that the math is mathing. The little blocks and axes represent the final foot bone orientation. This is the expected behavior. (Note …

I done figured it out! I still have some transition polishing to do when the feet come off the ground, but foot-to-ground orientation is now working. [Godot Devlog 3] I think I’ve now got a decent understanding of the SkeletonModifier3D and how you coordinate the various states of t…

Does your scene contain an AnimationTree?

Yes. And it sits before the skeleton/2BoneIk, per a note in the Godot Docs.

Yeah I think there’s just not a lot of information yet about working with the SkeletonModifier3D. I did read that page you linked, but I didn’t notice there was a demo project to download. I’ll give it a look. Anyway, I was able to confirm my suspicion that the issue is the bone pose feeding back i…

[image] cgcody: I think I’ve now got a decent understanding of the SkeletonModifier3D and how you coordinate the various states of the skeleton data through signals. Can this principle be used in the “opposite direction” — to modify the skeleton bones before applying animation — for example, …

I’m not at my computer to confirm this, so naively speaking, I would imagine so. But you would probably have some work to do in compensating for how animations would affect longer/shorter limbs. It would certainly be a direction to investigate. I’d be curious to know what you find out.

[image] cgcody: But you would probably have some work to do in compensating for how animations would affect longer/shorter limbs. This issue will arise with any rig other than the one on which the animation is being built. The plan is to solve it using IK. There’s also the interaction betwee…

I haven’t been able to get AnimationTree to work with SkeletonModifier3D. BTW, AnimationTree is missing from the example project in the official documentation.
