Creating a mask from Nulls

#1

I want to mask a building out of moving footage.

I have imported some tracked points into after effects. This has made 7 nulls (the different tracked points positioned around the building in my footage). Now I want to use the nulls as corners for my mask. How can I parent an individual vertice to a null allowing the mask to update with each frame?

Thanks

It’s not possible. You need to use scripts to transfer tracking data to masks like this one: http://aescripts.com/tracker2mask/
