Hi, i am using the beta specifically for a project taking advantage of the new Track Matte feature as i have a ton of layers.
Unfortunately, i just tried to parent 4-5 layers Track Matte to another layer with the pick whip for the track mattes but it only link the first selected layer. as opposed to normal parenting, which lets you parent all selected layers in one drag of the pick whip.
This is a must as after pick whipping all my layers one by one, i realized i track matted it to the wrong layer, and had to do them all again, one - by - one.
This would be a nice fix to have soon, Thanks! 🙂
