When texture compression is used (new feature of Verge3D 4.0 pre1) with a scene that uses AR, it makes it so you can’t launch augmented-reality. I’ve tested on an iPad and iPhone. I’ve tested my scenes as well as the augmented-reality demo.

Also, neither of the two compression types work with an AR scene.

Is this a known issue or is there some workaround so that I can use texture compression with augmented reality like normal?

Hi,

sorry for the delay. I’d recommend rolling back to v.3.9 as the 4.0 preview build is highly unstable.

Hi,
please wait a bit till 4.0 pre2 release is out. We’re going to make it way more stable than 4.0 pre1

Thank you guys for the replies!

Ok I understand.

This pre1 build is working pretty good overall and I’m really using the new line render feature and the full 360 degree vertical camera feature that I requested so I should be ok to continue using this build til the next one comes out. :)

Note: The ‘open webpage’ puzzle doesn’t always work on the pre1 build, just so you guys know about it.

Thanks again! You guys are awesome!

Vern

Hello!
I just updated to 4.0 pre3 build and the new texture compression still disables all AR functionality. If I turn off texture compression, my scenes launch in augmented-reality with no problem as expected.

I was really hoping the new builds would fix this.
Will this be fixed soon do you think?

Hi,
Looks like some hardware-dependent issue. What phone model you have? Does your app work on other devices?

I tested it on my iPhone XS Max and my
iPad Pro (12.9-inch) (3rd generation). It’s the same problem on both.

Do you think it’s iPhone/iPad related or all mobile devices?

Any updates on this issue getting fixed or why it isn’t working?

hi,

does the stock Augmented Reality demo behaves the same way for you?

Hello Yuri,
Yes, the exact same issue happens on the Augmented Reality demo. I did make sure to update, and re-export the model, etc as well.

I’m running iPadOS 15.2.1 on my iPad and iOS 15.3.1 on my iPhone.

Is this a device specific issue? Also is there some workaround or fix for the time being?

Hi,

the problem is that WebXR is still unsupported by iOS Safari. Therefore AR content is rendered via built-in USDZ viewer and not via WebGL. Hence compressed textures cannot be used as this is part of WebGL.

As a workaround, you can create a separate asset to load on iOS, or just disable texture compression.
