BABYLON.BoneIKController With GLTF Mesh

Questions
45

Not sure how the API is structured, but also not clear if absoluteRotationQuaternion uses .rotationQuaternion. If .rotationQuaternion is null, this would break

46

Makes sense but may I ask what none desired side effects the intermediate scale is having ? I am still confused of why not keeping it in as we do for the root node ?

Hey @Sebavan

Thanks to yours changes, for this post, I used the BoneIKController with GLB files, but the BoneLookController don’t work yet with GLB files. The change to be done are not similar with this one?

50

Adding @bghgary as I am wondering if the latest changes he did on skeleton for gltf might have regressed the IK changes with transform nodes ???

52

Do you have a playground I can investigate? What kind of issues are you having?

53

Hi @bghgary

Yeah, I did one BoneLookController | Babylon.js Playground (babylonjs.com)

In it you can see that BoneIKController is working with GLB file, but the BoneLookController do not.

But in the meantime I discovered that I can use just the LookAt() method of the bone TransformNode (uncomment line 77 and comment line 76) .

But the changes @sebavan did can’t be done in BoneLookController too?

54

Completely misunderstood, glad to know it works on IK :slight_smile: I ll have a look at the look controller
