Hey all, I'm new to Nuke, coming from Fusion, and I'm not totally clear on the best way to attach a besier roto mask to a track in Nuke. In fusion you'd right click on the polygon mask, and use the Attach mask to track script, select your tracked path, and bam, it's attached. Is there similar functionality or a simple script to do this in Nuke?
Thanks!

First you have to track your plates using a Tracker node. In the Tracker node, you have a Transform tab which contains translate, rotate, scale and so on. After you have done the tracking it will have values that are derived from the tracking points.
In the RotoPaint node, you have a Transform tab for each shape. It is located below the list of shapes.
Click Ctrl and drag the values you need from the Transform tab of the Tracker node onto the Transform tab of the RotoPaint node. Typically those values will be translate, rotate, scale and center. That will create an expression that will tell the Rotopaint node to take these values from the Tracker node.
