Hand Tracking without rotation

  • Hello Kitty,

    You can use the script for attaching 3D object which you can find it here:

    Make sure to uncheck apply rotation and it will fixed to it own rotation.

  • Hi,

    Is it possible to lock rotation for 2D files as well or is just limited to just 3D objects?  I would like to be able to track a 2D animation to the hand with rotations locked as well.

  • Hey Kitty,

    I just made a project file for which is rotation is locked on the HandTracking which you can download from the link down below:

    They way that is done is every frame we update the world rotation of the object to the rotation that we want. if you look at the script I added these two lines in the onUpdate() function to set the rotation every frame:


    function onUpdate( eventData )


    if( initialized&&script.smoothFollowing )


    smoothFollow( targetToFollow, script.smoothFollower , script.smoothingSpeed );




    var rot = quat.fromEulerAngles(0, 0, script.handRotation*Math.PI /180);



    Hope this will help you and have fun creating lenses.
