Trying to Change TrackMat Setting
Hello there!
Scenario: I am currently trying to change a layer to an alpha matte. However, no dropdown menu is displayed in the Trkmat Column.
Question: How would I do get a dropdown menu to select which type of matte I need for my project?
Ideas: Is it something to do with toggles & switch modes? Must it be in a comp with multiple layers?

Thank you much!
