I created 4 markers and used them to 'Create Plane Track'. This worked fine.
Then, in the compositor, I added a 'Plane Track Deform' node, selected an image for it, and chose 'Camera'. Clicking on the plane track dropdown, I don't see my plane track. The dropdown is empty.
What am I missing? I looked at tutorials, they all just pick the plane track from the dropdown, and mine is empty. Could it be that the plane track is not associated with the camera?
Any idea what I'm missing? Thanks.
