I would like objects in my unity project to be occluded by humans and other inanimate objects. The problem I am facing is that the objects in my scene are always superimposed on humans and other opaque objects. Would I have to change Unity editions completely? I am running unity 2020.3.7f. The HoloLens definitely should have capabilities for what I am seeking, but I can't find how to do so.

Hello, welcome to Microsoft Q&A,
According to https://learn.microsoft.com/en-us/windows/mixed-reality/design/spatial-mapping#occlusion, if you need occlusion for your game object, Spatial Mapping needs to be enabled in your Unity project. Please navigate to [MixedReality Toolkit Component] -> [Spatial Awareness] -> [enable Spatial Awareness System].
Based on your selected Spatial Observer, you can change the display settings. Choose “Occlusion” from “Visible” in Display Settings to hide MRTK built-in Wireframes.

Thanks for your help! My project is about puncturing someone with a needle. Would I need to include any occlusion settings to that object in Unity?
>puncturing someone with a needle
It sounds more like a Unity Collision issue. If you want to have physical collisions for game objects, RigidBody components are required for those objects. Meanwhile to ensure it works like common Holograms, you may enable “Is Kinematic” or disable gravity according to your requirement.
HoloLens occlusion is something different, and it ensures the objects will be occulated outside of room boundaries to emulate the real-world behavior. Please let me know if I understand correctly. Thanks.
I believe you understood my problem correctly. To clarify, I need the virtual needle to puncture a human body and stay stuck in that position. I am able to do so right now, but the part of the needle that is "inside" the body is not opaque. I'm going to look into the Unity collision property. Would that property stop a virtual needle from entering a human completely? Thank you so much for responding. I really appreciate this help. I've been stuck on this issue for a large portion of time.
Is it a virtual human body or a real one that you observe in HoloLens 2?
