Hi People, I have imported a rigged model (dude model https://github.com/BabylonJS/MeshesLibrary/tree/master/Dude) in my project, the method scene.beginAnimation() works so i suppose that the skeleton is already attached to the mesh. I want to rotate a bone of this skeleton but i can't reach this goal The code that i used is the following: engine.runRenderLoop(function () { var bone = scene.getSkeletonByName("Skeleton0").bones[20]; //I've tried different bones var boneMat = bone.getWorldMatrix(); BABYLON.Matrix.RotationXToRef(0.1, boneMat); bone.updateMatrix(boneMat); scene.render();}I have no result, do you have some hint?
