I made a Picture Frame Generator!
The frames in the video were created with this NodeGroup 
Flexible sizing and passepartout settings.
I am using input curves as profiles here so you can create any frame you like.
Frames are procedurally UV unwrapped so you can apply any textures.
The product also includes 10 configurable frames and with the geometry node groups, opens up to infinite variations to suit whatever scene you’re building.
CC0 materials are included.
It’s also set up as assets for easy use.
Available on my Gumroad.
