    Hi Professionals,

    I have a simple question:
    I have an Alpha Matte turned on but after I turned on the 3D layer, the Alpha Matte stops working. Here are two screenshots:

    Can anyone kindly advise me on how to adjust this tiny problem? I’m still pretty new to AE…

    Thank you so much!!!
