I was wondering what would be the approach to achieve the following effect:
Mainly I am concerned about two questions:
1. The picture frame as a 3d object shows an entire world behind it, yet it is masked in some way outside the borders of the frame. How would you achieve masking the interior of a certain element, such as this, or a hole in the ground or etc.
(I have tried using a simple worldPosition mask material, as suggested here
but it masks out the entire object from a certain point in space).
2. In the case that i would like to use a 2D video on a physical screen, instead of the 3d element such as the frame, and make the air-plane pop out as an AR element right at the moment it has reached the surface of the screen in the video. What could be the best approach for doing so?
