No multimode, it might have been broken since v62. Note that all the samples are core so if your project is URP remove the reference to the pipeline asset from Graphics.

Very usefull

The actual sample scenes have to be imported separately within the package manager. After installing from package manager, go to the package in the package manager and navigate to the samples tab. Import the desired sub-packages. I have no idea why they did it this way. There is no direction or instruction and its extremely confusing. Downloading a samples package should just include the samples as stated in the description. You don't need a sample of a sample. Seems like they are misunderstanding the purpose of that feature and how to utilize it.

used to be very easy to use its now very difficult in implement, please reverse the function of "UI HELPER" in the latest version it is very helpful for USER INTERFACE

Locomotion scene and all other scenes don't have colors. Why? They look like foggy, is it a bug or I'm missing something? For unity 2023.2.8....

I've been dabbling in XR dev since Quest 1 released. Back then the Oculus documentation and SDK's were impossible to follow and I learned more from just watching youtubers creating OpenXR dev content. I gave meta's SDKs and documentation a shot as i'm diving back into dev more deeply and have been pleasantly suprised with how well this seems to work. In about a day I've gone from nothing to a functional prototype of what I want to create all using only Meta's documentation.

It's hard to do it worse. It doesn't work in the latest versions of Unity nor in those prior to 2021, you have to keep trying until you find a version that stops giving errors and coincidentally works. It should be a single SDK package that you install and that's it, not 10 different asset packages where you don't even know which one to use. And then why split it into so many packages if they depend on each other and you end up having to install them all anyway? And finally, why hide the examples in the package editor so that you have to go there to a hidden button to install them? Years ago, it was all simpler, a single SDK that didn't give errors and was easier to install. Terrible.

I spent ages trying to make hand tracking work. When I switched to URP it work out of the box. Letting us know somewhere in description would be nice

It use textmeshpro, this is not longer supported by unity 2023.2

Works great, I searched for the Samples like every other reviewer down here did - and I found them. - Prefabs: They are in Packages/ now instead of Assets/ - Scenes: They are still there, but you need to install them in the package manager. There is a "Samples" Tab in between "Dependencies" and "Images", there you can install each sample folder independently. https://communityforums.atmeta.com/t5/Unity-VR-Development/Seeking-Guidance-on-XR-interaction-SDK-sample-scenes/td-p/1103794
