Use NumberKeyframeTrack for own properties

Currently I use serveral NumberKeyframeTrack via PropertyBinding to control the morphtargets/blendshapes of a face. Now I want replace the morphtargets/blendshapes with bonerigs to control the face animation. So I want to control a bone or Object3D with the values from the same NumberKeyframeTracks.

Is it possible to map the number PropertyBinding to an own number property in a derived object2d class in the scene graph? In the source I saw only a binding to “morphTargetDictionary”

Have you any hints for me. Thanks, Christian

The following example shows how you setup keyframe tracks for animating arbitrary object (and even material) properties.

If keyframe tracks are already existing, you can change the name property to target a different object property.
