Physical transition between rooms in XR Quest 3 - How to?

Hello,

I'm making a mixed reality app, and I have scanned two rooms in my house. I have used the Passthrough, MR Utility Kit and Effect Mesh building blocks, but I can't move between rooms without the screen getting covered up in grey, even though I can see the other room being rendered in the effect mesh.

How can I disable this "out-of-bounds" effect in order to transition physically between both rooms?

The first image is from the room I started the app, the second is from the second room looking towards the first.

Hello there!

I see you're curious as how to remove the boundary screen. If you go to https://developers.meta.com/horizon/documentation/unity/unity-boundaryless, this our article about how to use the Boundaryless API. This can remove the boundary for a section, or all of your app. I'll also note that for safety reasons, it's only meant to be used in mixed-reality apps.

Hope this helps!
