    @stellar, you can’t, those are generated automatically and are used by your graphics card to displace the mesh. But the more points you have in the mesh, the larger this texture becomes.

    @stellar it might be due to large shapekey textures:

    thanks, that’s a clear sign that Apple is doing something very wrong in the latest iOS versions. In this thread:
    https://forums.developer.apple.com/forums/thread/737042
    someone states:

    According to our investigation the issue can be triggered by the usage of the flat qualifier.

    No idea what that means though

    Interesting
    I get a hang already on the third tab on iPhone 14 Pro with iOS 17.4.1

    What iOS are you running on that SE?

    hi @alexander-kovelenov

    In the meantime I did make a few changes based on suggestions by @xeon, turning off the lights in the scene and turning off HDR rendering. Try opening the app in several tabs, and you will see it starts behaving badly. Or open the app in both safari and chrome at the same time.

    I think it is likely to happen if a customer is going to open the app multiple times to compare several options, or maybe even inadvertantly because they leave the app open on one page and open the app again at some other point on a new page, but this is not sure of course. I’m happy to hear though that the app runs on phones you tried. Are these phones all on 17.4.1?

    When the app is open on multiple pages/ browsers something is going wrong, and I don’t know what it is, which makes it hard to debug. Is it memory? What causes the model to turn black or loose context?

    @xeon thanks for having a look, I sent you the project file + Blender file

    @xeon thanks for having a look. The project file can be downloaded here

    I turned off hdr rendering and removed the lights, that at least makes the app load again on phones that previously didn’t. I do not want to share the model here, but if I can send it to you directly that is fine.

    @xeon @kdv77kdv,

    thanks, I am going to try out your suggestions and see what can be done.
    Since the app is controlled by external website, I had turned off the controls, but you can now see the controls again on the link I sent.

    The project has been a bit of a moving target and is currently quite complex.

    @yuri I have a similar problem with my application and need urgent help, since the app is now not loading reliably on iOS. The above instructions are not completely clear to me.
    How do I force a reset of the app when the user reloads the page? Using the unload scene puzzle somehow does not work for me, since that messes up everything. So what I am looking for is something that makes sure the scene is not kept in cache, at least that’s my understanding of why this might happen. I wonder though why this only happens on iOS.
    Even when it does work sometimes, I still see that content gets lost

    I tried the following. I installed Chrome browser on the iphone and started chrome://inspect
    then I open a new tab and load the app.
    It loads well, and I get:
    LOG Verge3D 4.5.1 for Blender (License, WebGL 2.0) so all seems good

    When I reload I sometimes get a correct scene, sometimes not, and this message:

    LOG Verge3D 4.5.1 for Blender (License, WebGL 2.0)
    LOG v3d.WegGLRenderer: Context Lost.
    LOG v3d.WegGLRenderer: Context Restored.

    I see part of the page, but the scene is not correctly loaded. Sometimes it just gets stuck on the preloader.

    EDIT: the above seems to happen only when I load the same page also in Safari. So it appears to me that there is an issue with Safari. If I close Safari down, the page loads correctly again.

    Thanks in advance for your help.

    The app is https://v3d.net/ukb

    Some more info: the app runs fine on ipad pro running iOS 16.5
    Also running fine on iphone pro max running 17.4.1

    I further see:

    and:
    https://bugs.webkit.org/show_bug.cgi?id=268070

    how do I verify if the above is the case in my shaders?

    @yuri, it’s been a few days since it was reported that booleans currently don’t work properly. Any news on this matter?

    I hope @yuri is aware of this bug?

    I tried to find a workaround by rebuilding the objects directly in Verge3d, but it seems I cannot make a proper boolean difference from more than two objects. Example:

    https://cdn.soft8soft.com/AROAJSY2GOEHMOFUVPIOE:606b34768b/boolean_fail/boolean_fail.html

    Basically I am making a Boolean Union out of two rotated boxes and use that as a cutter to cut two corners of a box. Two subsequent Boolean differences also fail, though in a different way.

    What am I missing? Are there any examples on how to subtract multiple objects at once?
    It seems it should be possible if I look at this example:

    I suspect it should be possible to bake the shapekey modifications into the object.

    hmm, doesn’t work on objects with shapekeys applied, rendering this pretty much useless, or am I missing something?
