using UnityEngine;
using UnityEngine.Playables;
using UnityEngine.Animations;

public struct PropertySceneHandleJob : IAnimationJob
{
    public PropertySceneHandle handleR;
    public PropertySceneHandle handleG;
    public PropertySceneHandle handleB;

    public void ProcessRootMotion(AnimationStream stream)
    {
    }

    public void ProcessAnimation(AnimationStream stream)
    {
        // Log the light color.
        var r = handleR.GetFloat(stream);
        var g = handleG.GetFloat(stream);
        var b = handleB.GetFloat(stream);
        Debug.LogFormat("Light color: (R: {0}, G: {1}, B: {2})", r, g, b);
    }
}

[RequireComponent(typeof(Animator))]

    public Light sceneLight;

        var animationJob = new PropertySceneHandleJob();
        animationJob.handleR = animator.BindSceneProperty(sceneLight.transform, typeof(Light), "m_Color.r");

        m_Graph.Play();
    }

    void OnDisable()
