Hi all, I've just upgraded from Express to Pro and I am having a real hard time achieving the result I want with a particular comp so I thought I'd ask for some advice.
Using this video, I am trying to track the top of the truck as it moves along, so that I can overlay another comp of a circular sign above it. The aim is to make it appear that the sign is floating above the top of the truck cab as it moves along the road, like this (screenshot).
At first I thought Foundry Cameratracker would track the truck as a 3D object allowing me to "pin" the sign to it, however I've found that it only tracks the ground plane and the camera's progression along it.
Then I tried Mocha, adding a spline to the top and side of the truck, but Mocha couldn't seem to track either plane all the way, potentially due to contrast issues.
I then tried a two-point track on the front-facing corners of the top of the truck, this gave fairly good results except for at the end as once the truck has gone off screen I've had to guess where they go and don't seem to be able to get it quite smooth enough to look real.
Hoping for some advice from the community.
