Hello,
When updating to iOS (iPadOS) 18.2 or later, there are devices where the scene becomes dark and cannot be rendered correctly.
It is likely dependent on GPU performance, but is it difficult to resolve this issue?

Hi,
Could you check if opening a scene with the following flags fixes the issue: #no_reflection_probes&nobrdflut ?
For example: https://demo.shapespark.com/demo-room/#nobrdflut&no_reflection_probes
Just remember that once you get a black-screen on your browser, you have to restart it for Shapespark to start working again. Without restarting you will get a warning about missing GPU capabilities, as You’ve shown on the second screenshot.
We are actually investigating this issue, it seems quite tricky.
It’s possible that in the latest updates to iOS Apple introduced some mesures preventing misuse of GPU computing power. And when some shader does too much computation the driver might simply cancel the computation, which may lead to black screens in the browser.
Hi @Krzysztof, thank you for your reply.
I tried adding the flag, but it seems that the flag does not work for scenes hosted on our own server.
Is there any workaround for this?
Hi,@krzysztof
I had set the flag incorrectly.
By adding the flag you taught me, it worked without any issues.
Your advice was very helpful, thank you!
Thank you for checking this!
We’ve prepared a potential fix for this problem, but it’s not fully released yet.
Could you check if it solves the problem for you?
To do this add the following text at the end of the url:
?webwalk=1156
For example:
https://demo.shapespark.com/demo-room/?webwalk=1156
This fix should be better than the previous one with #no_reflection_probes, because the reflections won’t be disabled.
Thank you for looking into the problem.
I tried changing the end of the URL and testing it, but the scene turned completely black.
However, any solutions that do not disable reflections would be very useful, so please continue to support us.
Facing the same issues since I updated my iOS version.
Is there any update on when we can get perfect solution?
