Hi friends, I see this question has been asked a few years ago, and most results suggest a feature request… I’m on 2025.2. … any chance this has been updated and you can now, in some way that I’m not seeing, use a matte (not live gmask) as an analysis constraint for planar tracking? I’m thinking no… but worth asking. Thanks!
If you temporaritly mult them with your fill, the places not in the matte would blacked out and untrackable, no?

Unfortunately it would then just track black objects instead of the info you want to exclude. Using them as a matte input also doesn’t work; when you F8 and snap to view the track ref, you still see the objects that need to be excluded.
Track the roto with a gmask and then use that as the exclusion?
I played with it some last night. There doesn’t seem any way still. Unfortunately the gmask link only works from a gmask, not a surface with alpha. Otherwise you could route that way. And the inclusive/exclusive options don’t help.
I guess retracking the matte may work depending on shape and details. I would use Mocha magnet tool and then export Mocha layer as gMask into Flame.
Of course at that point you could do the planar tracking in Mocha where exclusion may be more versatile.
Not strictly planar tracking, but the mono analyzer will take a matte and frequently works quite well for planar and object tracking, particularly when combined with motion vectors.
