    I tried to open this link in Safari on an iPhone and it loads the page three times and craps out. Same thing in XRViewer. It works fine on a desktop, and on my iPad (iOS14.7.1). Any idea what’s causing it? This could be a deal killer for this client.

    Here is the link:

    I’m attaching the screenshot from my phone.

    Hi John,

    your app loads too many big (2k) textures, and iPhones have too little memory. Try to reduce texture space, or make a low-end scene specifically for iPhones.

    Sry to hijack that thread, I’ve experienced that iOS issue too many times. I also did notice that it was related to the memory management in iOS. But I wasnt able to find a specific value were that limit is. Do you have any detailed information about this Yuri?

    We cannot say the exact limit, since WebGL (and the browser itself) is a complex system which distributes hardware resources on its own. All we can recommend is to test out your app on real devices.

    Thank you very much! I’ll try that immediately.

    Okay, I’ve reduced all the textures to 1024×1024 or smaller, eliminated a large number of them, and tried again. Same problem. I even made sure to remove all website data to soft8soft in my iPhone settings.

    New link to look at the app:

    I reduced the textures to 512×512 or smaller, still not working. It’s very frustrating. If you can’t help, I’ll just try eliminating meshes until something works, I guess.

    Hi John,

    I invoked performance profile on your Verge3D scene (hot keys P-P-P , works without iframe) and it shows that it uses a very big shadow map (16k x 8k). Such a map alone occupies ~0.5 Gb of memory.

    The reason for that is that Point lamps use cube maps for rendering shadow (6 maps atlas), and in your shadow settings you set their size to 4k.

    This is really slow and takes a lot of memory so I’d recommend disabling shadows for your Point light (or make shadow map size 256 px).

    Thank you again! That did the trick. Your technical help is, as always, awesome!
