Title/Action safe overlays or 2.35:1 Mask in PIE?

Hi guys, I’ve been previewing some assets for VP and I have masks/overlays working fine in the editor.

Next I was hoping to get those same overlays/masks in PIE and saw this doc:

I followed the instructions closely, (made it full screen, added console commands etc) but I can’t seem to get the same results (or any masks at all) as in the doc.
To make sure it wasn’t something weird with my project I eventually started a new (clean) project with the third person template and had the same non-results.

  1. Am I missing any assumptions just going by these docs?
  2. For my fellow VP folks what overlays have you been able to achieve during shoots? (I’m currently using a lo-fi AR Kit setup)

Any advice is welcome, thank you!
