    I have a PlayableBehaviour that looks like

    Code (CSharp):
    1. [System.Serializable]
    2. public class BindableObjectAssetBehaviour : PlayableBehaviour
    3. {
    4.     public Color ColorValue = Color.white;
    5.     public float FloatValue = 0f;
    6.     public int IntValue = 0;
    7.     public bool boolValue = false;
    8. }
    9.  
    10.  
    It looks fine in the inspector (everything is serialized)

    However in my track, I can't animate the int value. All the others work fine. Any clues as to why this might be? upload_2020-5-4_11-43-52.png

    Integer animation isn't supported when animating playable fields.

    Got it.

    Any particular reason? It works with Animator tracks I think? I guess the workaround would just be to floor/round another float value, but no easy way to snap the curve to an int value I'm guessing.

    No real technical reason. The playable animation system is not the same as the regular animation system, and the task to add integer support just never had priority.
