Planar Tracking - External Mask (Alpha)

Hello my fellow Flamers! First post here. (So hope im doing everything correctly :sweat_smile:)

I’ve stumbled across a problem and i would love to share it with you guys and see if there is an actual way of doing this.

In the plate that im working on, i have to retouch a panel behind some actors. My idea was to planar track the panel by occluding the actors through a mask i generated through AI. But i cannot atach this external mask for the “Exclusion” parameter on the planar tracker, the only option it seems its through a proper Gmask done manually.

Is there any way to actually atach into the planar tracker an external alpha?

Of course theres always a milion ways of doing this shot, but it just came to my mind that this should be somehow possible?

Thanks a lot!

Following, never quite figured it out either.

as far as I know it’s not possible to feed it to the planar tracker as an explicit exclusion like you can with gmasks. I’ve had some luck in the past with just cutting a hole in the plate with the external matte or using pixel spread or something similar to infill the occlusion area with the external matte before tracking, but neither works perfectly.

As far as I recall you must make it within the gmask tracer node. However, it only needs to be rough.
