Hey, I'm one of the developers of XRI! Really happy to see you talk about our package in this video.

A few thoughts and answers to your questions:

- Why isn't XR Hands a part of XRI? XRI is meant to be an optional package that lets devs build rich interactions for their XR apps, but it's not a core input package, like the OpenXR package. The idea is that whether or not you use XRI, you should still be able to use hand tracking.

- Input readers, your example showed referencing interaction events. This was supported before. The new readers are meant to replace the action based controller, where you had to decide all the input actions you'd ever need, and the interactors would have to read their transform and input values from this. Its was problematic because, notably with hands, you'd often have different poses for different interactors, and you rarely needed all input actions for all interactors. This makes it a lot more modular.

- Near Far Interactor - a huge benefit of the new design is that casting is modular and it's easy to implement new strategies for getting valid targets without having to override the whole interactor. We also pulled out attach transform manipulation, and added a push/pull gesture. It should be easier than ever to implement custom behavior, like say the gravity glove mechanics from half life alyx, just by making a custom attach controller.

For extra info btw, we finally published our GDC talks online.
Here's a link to the playlist, including my talk about XRI 3.0.

I'll also be doing a livestream tomorrow, for anyone who wants to ask questions and watch me dive into XRI 3.0

Adaptive probe volumes look sick, and I realized I'm not using nearly enough light probes. Thanks for the video!

[Zeldarulah]

That foveation pronunciation was something else

[beardordie]

"Four-vation level". 10/10 pronunciation. Lol 😂

[SamOnTehsea]

I can't wait for your updated tutorial. After it my project will stop yelling at me.

[hawkwoodcom]

XR Hands is the OpenXR backend tech for hand tracking that any XR toolkit can use, not just Unity's XRIT. Keeping them separate is good.

[thorsten]

I am looking forward to it. The current Interaction with inheritance is a bit to complex for my taste. If you want to have different behaviour you needed have multiple objects and turn a lot of stuff off and on to get the designed behaviour. (At least how I made it to work..)

I hope it is getting better and more structured, that making adjustments gets easier.

🤣I keep wanting to & trying to use U6, but... it's new, so about 80% of my assets don't want to play nice with things. Ah well, it all looks promising at least.
Oh, and there's no R in foveated: "foe-vee-ate-ed".
Thanks for the update! 👏

Hey, thanks for hard work.<3
I am a beginner in VR game development and trying to delve deep into it. I’m unsure whether to start with Unity 6 or go with a previous version. What do you recommend? As you mentioned in the video, the performance of my project might be better with Unity 6 if I can work properly with it. However, I’m concerned about potential difficulties. Any advice?

[sappalele_dev]

Love your content my dude, hands down one of the best unity XR explainers in the game.

[tufanaydin]

Thanks for this video but Quest 3 can handle these APV, Gpu Residant Drawing or Gpu Occlusion Culling?

[DigitalAdamTech]

Do you know if the XR Toolkit uses Meta's MultiModal, allowing a game to be created with both Hand Tracking AND controllers?

[keirvr]

What is the colorful space game in the intro?

[dfadir]

I would love a series of 3 videos of max 10min each where you speedrun the creation of a veeeery simple Immersive Sim using the XRTK 3.

[CactusVRstudios]

I upgraded my existing project to XRI3 and everything stopped working. Now I gonna rebuild a new code foundation based on Unity6 + XRI3 for the next installment of Cactus Cowboy.

[lightoflifegames]

what game is that? with the spaceship?

[lunarvoidvr]

can you make a tut0orial on how to add physics hands

[messapatingy]

"Foveated" is pronounced as foh-vee-ey-ted. Here's a breakdown of the pronunciation:

"Foh" sounds like "foe" (rhyming with "go").
"Vee" sounds like the letter "V".
"Ay" sounds like the letter "A".
"Ted" sounds like "ted, " as in the name.

[spyboy_]

Foveated (foe-viated), not fore-vidded

[MrMycelium]

1:00 It's pronounced "FOH - VEEH- ATE - ED"
