invisible occlusion material AR (IOS) project

Hello all,

im working on building out an AR experience on an Ipad and cant figure out how to get this effect…for example if I place spheres inside of a box with the top surface removed (so 5 sided) I dont want to be able to see the box with spheres inside unless im looking from the top of the box…so if i start on one side of the box it will look like nothing is there as i move to the top of the box, i can start to see the inside surface of the box then as move over the top i can start to see the spheres inside

I think the key to getting this to work is some of the materials inside the “Apple ARKit Content” and / or “AR Utilities Content” Im still newish with unreal and haven’t been able to get something working

Help with this would be greatly appreciated!!!

here is another thread that goes into depth but didn’t really go over the solution clearly (imo) Render in main pass AR (Android) - Development / Rendering - Epic Developer Community Forums (unrealengine.com)

this is another visual example of the effect

Im using UE 5.2 and Ipad pro

Inside the Apple ARKit Content folder (you have to change settings to see plugin folders) there are 2 materials (MI_DepthOcclusionOverlay and MI_MatteOcclusionOverlay) that I think will work but when I apply them they arn’t working as intended…do I need to add blueprints to the level BP in order to get it working?..im not sure what im missing

Thanks
