Recap thread of my @Official_GDC talk yesterday, “Up Close & Virtual: The Power of Live VR Actors” for anyone interested in #MetaHumans #VR #Theatre #LiveEvents #SocialVR #CloudXR #CloudGaming. It will also be available in the GDC vault soon.

I started w/ my 2008 London story about how watching the best performers in the world from the front row had a profound effect on me. It’s different from a film close-up or from sitting in the back seats. You can hear some of the story in my #GTC21 talk:

@nvidia

Then I did a speed run of my work in #XR for designing real theaters before jumping right into showing Christmas Carol.

I enumerated 3 things that made this show possible:

1. Cloud computing (thanks @nvidia)

2. MetaHumans (thanks Epic)

3. Live Link Face (thanks Epic again)

Then for context I did quick dive into #AliveInPlasticland and #OnBoardXR to discuss the affordances and limitations of social VR and why it would be great to have a platform that is tailored to high-end, expressive live shows.

Which of course is what we’re building at Heavenue.

Here’s the very alpha demo I showed of the Heavenue Cloud Editor. Our first goal is to shorten the time to build & refine a show like Christmas Carol from 3 months to about 3 hrs. You can bring in assets, set up stage cues, & publish. All from a Chromebook if you like, bc cloud !

@xractor

This was immediately followed by a (dangerous!) live demonstration of turning off @xractor's facial recording while leaving his body animation intact so I could take over the role of Scrooge opposite Marley. Was flattered by the spontaneous applause 🥰

Out in the hallway I then spent the next couple hours giving demos of the different setups and answering questions, which was a blast.

@HeavenueXR

Conference wifi was fine for broadcasting #LiveLinkFace, but to demo @HeavenueXR cloud VMs on Chromebook, a Windows laptop, an iPhone, and a Quest, I ended up using my mobile hotspot! Scared to look at my data usage for this week 😂

@steelmanxr

Great to see @steelmanxr, who asked this great question about how a performer can 'look at' an audience member in #VR. Ideally the performer is in VR too, but we have tricks to help, like a screen for reference and snapping. Also I'll only be taking questions as a MetaHuman now.

Hal from Meta was hilarious. I like this part where she started to give acting instruction. "Bigger, dear!"

@BtweenRealities

Such a blast giving such a wide range of cloud demos. Oh also thrilled the @BtweenRealities boys @Alex__VR & @skeeva stopped by for a peek. "The best VR humans I've seen yet!" I believe they said, but no video to prove it :)

If anyone wants a demo this week, DMs are open. #gdc22

We're gearing up for our first public Quest store release and now properly jumping through all of Meta's VRCs. Here's a thread on some of the headaches we're encountering. I hope this will be useful to other #UE5 developers going down this path in the future. Enjoy! 😪😓😮‍💨

Let's start with .Performance.1:
Interactive applications must use a refresh of 72 Hz, 80 Hz, 90 Hz, or 120 Hz.

We're using the Meta Quest Developer Hub which conveniently throws up fps drop flags while in the experience, so we identified a few pain points VRC.Quest

On Friday, @RobertJALA kindly went thru various stat commands (stat scenerendering, stat rhi, stat unit, stat tickables etc) to identify elements in our scene causing the biggest bottlenecks. In our case, biggest one we hadn't addressed was materials too many individual textures.

So this works remarkably well. #tiltfive

I assumed I would need to flatten the fabric out and position it very precisely next to the board, but as long as the board is active it’s treating all retroreflective material as raw portal. And it looks super sharp!

@tiltfive

For those who haven’t tried @tiltfive it’s tough to represent how vivid of an #AR experience it is. The FOV is fantastic but you need enough real estate to project onto. Here’s a look through the lenses.

@sundancefest

Okay I think I've experienced as much as I can handle tonight for @sundancefest's #NewFrontier (it's been 45 min). About to post my learnings here to save you some headaches, tho hopefully some of what I've seen are bugs that will be resolved, or just me not knowing what to do 👇

First some compliments: the WebXR experience LOOKS beautiful (especially in VR) and is a lovely way to socialize... when it works. Most of the time I'm in an empty room even though there's a whole bunch of attendees here.

I do like the structure of how the rooms are broken down.

Some big picture framing up front: be in VR here to socialize (newfrontier.sundance.org & enter VR Code that you see on desktop), but don't expect to hop into any Gallery experiences directly. Signing up, downloading, or even setting up Quest view is wkflw best suited for desktop.
