I tried Dr Abstract < Transnomino < Dan Zen and ZIM in Virtual Reality - XR / VR / AR - with three.js today with the default browser on my quest3
I see the scene in the browser, but when I press the "enter VR" button on the bottom, then I don't enter VR, but I just see my see through camera's (because thats how my quest is set) and 3 animated dots. I don't know if this is a ZIM loader or something on my quest, but I guess its on the quest.
So... I don't see to be able to enter VR mode on these 2 pages. I did get a question the first time if I allowed immersive mode which I of course did, but that doesn't change a thing.
When I surf to other websites (like babylonjs webxr demo) then it does work.
So can something be wrong somewhere?
Kind regards,
Bart
Nobody have an idea? Or can somebody replicate this?
Oh - sorry! Lost the thread. My headset is not reading my controllers at the moment. Will try perhaps to do a system reboot after a nap.
I do know that the sites were working last time I tried during the Dr Abstract creation. Let me ask a few friends here...
broken for one friend... got in but no interaction and then next time did not get in. Sounds like an error that stops it running the first time and once that happens, you need to clear cache and try again - but will get the error again. I have not changed code since it was working for me... so maybe a new browser version is breaking something. Will try and reboot mine so I can debug.

little follow up. Upgrading to v72 of the quest3 firmware didn't solve the problem.
But.... I found something interesting in babylonjs
In babylonjs if I select rendering as WebGL of WebGL2, then I could enter the vr scene of a babylonjs demo. But when I selected WebGPU, then I got the same 3 loader dots that I see with the ZimJs examples for XR
Maybe related...maybe not
I did a test with quest3 and had no problem with https://zimjs.com/vr so maybe test this one first Bart.
I was on Thomas More exibition in Mechelen with the quest3 of the school.. the proffesors tested ZIMjs and where very happy to see it working..

can you send a screeshot?
thanks
ZIM in Virtual Reality - XR / VR / AR - with three.js was literally the second link in my original post Karel, so unfortunately this is the one that doesn't work
Nope sorry, it does just the same. 3 dot loader and nothing happens 
I am putting on an event on Friday and racing around like a madman - making 10 games, etc. and teaching full days today and tomorrow. Friends are here from the states over the weekend, but will try and take a look on Sunday... although that is superbowl. Maybe Monday. Sorry for the delay on this. I would have checked already but my headest controls are not working - need a factory reboot.

It's no problem Dan, I just want to give as much info as possible. Who knows maybe I discover some kind of reason (or better solution)

Okay - got my VR helmet going again - batteries were in the wrong way so when I changed them, I put them in the same way and they were the wrong way still. The VR examples in ZIM and the DoctorAbstract site work for me on a Quest 3 default Browser. I will test later today to make sure I have the latest updates installed.
I still can't enter on the latest software version. Strange.
I just checked and I am up-to-date. I can get in - and recorded a vid for you. But it is a little temperamental. It freezes sometimes when I go to record a vid. Then I can't get back in until I clear cache or sometimes restart, etc. I really wish we could see errors, etc. I heard there is an emulator on the computer... will try and find that one day and see if something is triggering the freezing.
Been trying the emulator and unfortunately, no errors. There was one error in switching from hands to controllers and we have tested for that in a ZIM 017 patch. We are creating a set of tests and will send the links to them soon. Then you can run through the tests and see if any work - that may help us find the issue.
Test these out in a VR Headset. For movement use the sticks and the little A/B X/Y buttons to teleport.
They all work for us. We did have a crash with the first movement one (TEST 4) after teleporting and moving - but then it worked later the second time we ran it. That is good we got a crash on that one as it indicates that the issue is not related to TextureActives - but rather the controllers code.
Our crashes seem pretty intermittent and I think related to movement.
I will test this evening. BAtteries of controllers charging. I hope that it works.
I'm also interested in that emulator thingy where you seem to be able to test without vr set? Is that a chrome plugin or something ?

Okay so I can access these demo's in about 25% of the time. Sometimes they open, sometimes they don't. Sometimes they open and hang. It looks like at this moment it is working very unreliable. I think for the near futur I'll stick to developing 2D browser stuff
