So I am working on a foot snapping IK thingy and I noticed when resizing the parent/root mesh of the skeleton makes the composed positions based off of a bones absolute position go into the wrong place. Here is no scaling or position applied: Babylon.js Playground Babylon.js playground…

By default, the data returned by Bone.getPosition / Bone.getRotation / … is relative to the skeleton, not to the mesh (TransformNode) to which the skeleton is attached to. If you want data relative to a mesh, you can pass it as the tNode parameter of these functions. Doing so, the mesh world matrix…

I probably need to do bone.calculateWorldMatrix() or something huh?

From the deep end, could you not do whatever you are doing with the mesh’s matrix to the root bone’s? I do not really grasp the extra complications of GLB on skeletons. So ignore, if I am way off. BTW, I have a a very small subclass of BABYLON.BoneIKController (only 5 meaningful new lines), whic…

I might wanna take a look at that, because Im doing a fk/ik blending foot snap thingy to match walking animations to the terrain. Im really close just off of doing simple stuff, but I was going to dive in here and do an extension of the BoneIKController as well so taking a look at yours might be ni…

This was in a topic not completely related, so I tracked it for you. [image] The Studios suite Demos and projects I’ll just leave the sub-class here. export class BoneIKController extends BABYLON.BoneIKController { /** * A switch indicating that the rotation from…
