Trying to create AR hole-in-the-wall / portal effect with ARcore

Trying to generate an effect similar to this google ARcore demo:

I have got ARcore, UE4 source, augmentedimages and deployment to android working - so technically i’m ok.

Just trying to work out visually how to achieve such an effect? As currently - creating a blueprint with simply a box and elements inside them still shows the model through the wall when viewing from the side. The above effect is so mesmerizing as it looks like an actual hole in the wall.

ie: The issue really is how to ‘key out’ the sides of the boxes when viewed from the sides / not front on.

You need to create a pass trough material.

Wonderful! I will give this some testing now, particularly as they hotfixed some ARcore issues in 4.20.2.

So I’m assuming this material is applied to the interior of the box-like surface I’m making?

Did you manage to get a working solution out of this? Would need a similar effect for a current project and didn’t find anything useful.
