I have two scenes in my .reality file that was built using Reality Composer. The first scene gets loaded first, then after 1 second, I load the second scene. But this crashes the Quick Look app randomly. When I removed the Change Scene function, it works fine. I tested with IPhone 7. Any pointers to avoid the crashes?

Hi, I'm embedding the QLPreviewController in a UIViewControllerRepresentable. When I view .usdz models I don't see the AR/Object selector at the top, nor the sharing button. I have tried presenting modally with a .sheet modifier and had the same result. What do I need to do to get the controls? Thanks, code attached. Code Spiff

I'm currently trying to project a transparent .png file on to a flat surface (table/paper), but the shadow is giving me a gray box. I am a huge fan of the shadows in Reality Composer, however I'm searching for an option to adjust the opacity or turn off the shadow.

AR Quick View's AR Quick View button cannot be pressed on some iOS devices. As for the iPhone 12 Pro, the AR Quick View button cannot be pressed on iOS 15 when reading from the standard iOS QR code reader, but the AR Quick View button can be pressed on the iPhone 12 Pro with iOS 14. On other devices, you can press the AR Quick View button when launching from Safari, but you cannot press the AR Quick View button when accessing from the standard QR code reader. Also, on some iOS devices, the AR Quick View button cannot be pressed. The problem seems to be occurring outside of the https://konabeer.jp/beach-diorama-ar/ as well. Is there any way to avoid this AR Quick View button not being able to be pressed? It would be very helpful if I could get more information than just the solution to this problem. iPhone7(iOS13):OK iPhoneX(iOS15):QR Code Reader:NG iPhone11(iOS14):OK iPhone12Pro(iOS14):OK iPhone12Pro(iOS15):QR Code Reader:NG iPhone12(iOS15.1):QR Code Reader:NG iPad Air(iOS15):QR Code Reader:NG iPhoneSE(iOS15):QR Code Reader:NG As a result of our own verification, the AR Quick Look button is deactivated on iOS 15 and when the QR code is imported from the Control Center. If you know of any known bugs or workarounds, or if there are any informative sites that have information on this issue, I would appreciate it.

Hi! I've been working with AR Quick Look a lot recently and find it really useful. However, when I'm combining two .usdz-files into one, the experience isn't as great. I'm working with 3D-models that are supposed to be attached to vertical surfaces, and one by one they work flawlessly. But as soon as I add more models into the same, the objects won't "stick" as close to the wall as they do when they are separated. It's like there are some sort of "margin" applied to it. To create nested .usdz-files, I use Apple's command line tool: $ usdzcreateassetlib outputFile.usdz asset1.usdz [asset2.usdz [...]] Any idea why this might be the case? Thanks!

Hello, I have added the .usdz file in my website for iOS for a 3D model but it keeps giving me the error’ object requires a new iOS version’ when I click on the AR button. I have tried on multiple apple devices. Works great on android. Tried through safari as well as chrome. Any help would be appreciated. Thanks

One of people's favourite features of AR Quicklook is the video playback. Aside from the feature its self, what it represents is familiarity as people have used it in video for decades so it helps place AR right next to other common formats, which is awesome! Previously, if a USDZ's animation was longer than 10 seconds, the playback would appear. This rule was recently changed to allow the option from the USDZ metadata using the python tool. Unfortunately most designers are still not using the python toolkit so the feature is now hidden in most cases, which is too bad. Would be great to add the ability to set that metadata from Reality Converter & Composer. Better yet, if it was available as an html fragment identifier it would be super helpful, similar to "allowsContentScaling"

Hi guys, I have a little problem with Quick Look and I am not sure, if it is because of 3D model, iPhone 8 or if there is a bug from Apple side. What is hapenning? I am able to download 3D model to my iPhone 8, then I am able to place 3D model on my table and in the moment when I place it, Quick Look stop to work. There is this message: "model Universal Scene Description Package 2,9 MB" Do you know, where can be the problem? YT video: https://www.youtube.com/watch?v=wZKlPZUJkbk&ab_channel=AZtutorialy USDZ file: https://drive.google.com/file/d/1TcL4VoISRuMtdHd3XoW_Se4Lq6tNucYt/view?usp=sharing I am looking forward to read you answers. Thank you very much in advance Have a nice day Jan

This thread actually marks an unsolved problem as "accepted"/solved https://developer.apple.com/forums/thread/119265 As of iOS 14/15 Apple's own QuickLook does not support: On iOS and in AR, any USDZ with PNG transparency. It's a shame and testament to the AR dev team's (in)ability to address this issue. Multiple tweets and a basic google search shows this problem existing for over 2 years and now entering the third year. Meanwhile formats such as GLTF/GLB... just work

It's annoying that my image anchored scenes are migrating as soon as the image goes out of frame. Wondering if theres a way to make an image target anchored model stay put as a user moves far from the image anchor. Say 100 feet or so. I'm using this for house sized models.

Hi, I have build an experience with different hotspots. I hide them on start using Reality Composer. But they still show up in the Preview half-transparent object in Quick Look. (Before it's actually on an AR plane) How can I hide them for the Quick Look preview?

Hey. Anyone have experience build AR quick look from Reality Composer. How can I set the object always facing the camera during the AR experience. For now I can only do scene start trigger which only play once. Is there any way we can keep it alway facing the camera? Thank.

I've recently added some USDZ files to a web page, and I can download and display them fine via AR Quick Look on an iPhone or iPad. I've noticed full occlusion is active in the AR view. Over time, the device appears to heat up and the frame rate drops. Are there any properties I can set in the <a rel="ar" ...> HTML tag to control things like occlusion or autofocus (i.e., turn them off)?

I've been creating USDA files manually and converting them to USDZ via Apple's usdzconvert tool (version 0.64). In the file I set unit size to be 1 meter metersPerUnit = 1.0 but the USDZ keeps the unit size at 1 cm. Apple's Reality Converter does process the metersPerUnit metadata, so that is a viable work-around for me. But sometimes I'd prefer the command-line tool. Is there an update to the usdzconvert tool? I couldn't find one.

We are producing augmented reality in about 2 minutes with various scenes and animations. On ios14, everything worked without any problem, but on ios15, it suddenly says that AR Quick Look cannot open it. It seems that the reality file with a large capacity or two or more animations does not open. Please check. I attach a video that worked well on ios14. https://youtu.be/KPo_ikRclmc Thanks.

Hi all, I am able to create USDZ files to load in AR Quick Look. However, for prims that contain displayColor primvar values, they all appear incorrect (pink) when opened via AR Quick Look. To repro, create a usdz from this (size too big for attaching usdz directly): #usda 1.0 ( defaultPrim = "Origin" ) def Xform "Origin" ( apiSchemas = ["GeomModelAPI"] kind = "component" ) { string label = "Golden Krone Hotel" string modern_name def Sphere "Volume" ( doc = "This is the main volume for the Golden Krone" ) { color3f[] primvars:displayColor = [(0.721156, 0.0030596028, 0.27578437)] ( elementSize = 1 interpolation = "constant" ) double radius = 2 float xformOp:rotateX:tilt = 12 float xformOp:rotateZ:spin.timeSamples = { 0: 0, 192: 1440, } double3 xformOp:translate = (0, 2, 0) uniform token[] xformOpOrder = ["xformOp:translate", "xformOp:rotateZ:spin", "xformOp:rotateX:tilt"] } def Cube "TopBackLeft" ( doc = "This is the volume for the top back left section of the Golden Krone" ) { color3f[] primvars:displayColor = [(0.8052342, 0.0014515291, 0.19331428)] ( elementSize = 1 interpolation = "constant" ) double3 xformOp:translate = (-2, 6, -2) uniform token[] xformOpOrder = ["xformOp:translate"] } def Capsule "TopFrontLeft" ( doc = "This is the volume for the top front left section of the Golden Krone" ) { color3f[] primvars:displayColor = [(0.007277872, 0.58201957, 0.41070253)] ( elementSize = 1 interpolation = "constant" ) double3 xformOp:translate = (-2, 6, 2) uniform token[] xformOpOrder = ["xformOp:translate"] } def Cylinder "TopBackRight" ( doc = "This is the volume for the top back right section of the Golden Krone" ) { color3f[] primvars:displayColor = [(0.20229208, 0.39510167, 0.40260625)] ( elementSize = 1 interpolation = "constant" ) double3 xformOp:translate = (2, 6, -2) uniform token[] xformOpOrder = ["xformOp:translate"] } def Cone "TopFrontRight" ( doc = "This is the volume for the top front right section of the Golden Krone" ) { color3f[] primvars:displayColor = [(0.08033847, 0.7920769, 0.12758464)] ( elementSize = 1 interpolation = "constant" ) double3 xformOp:translate = (2, 6, 2) uniform token[] xformOpOrder = ["xformOp:translate"] } } Opening the file in USDView, SideFX Houdini, Autodesk Maya ends up in viewport displaying expected colors: Opening it in AR Quick Look iOS appears pink: Searching on the internet, I have not been able to find any information about why this happens, what the requirements are, or if it is a known issue. Only a post on usd-interest google group from 2019 reported the same: https://groups.google.com/g/usd-interest/c/8hD2rzRboeg/m/PSgIPlLCBgAJ with the answer: """ And I was just told that ARQL does not currently support vertex displayColors in any capacity - neither without a bound material (as in the example I provided), nor as something read via a UsdPrimvarReader shader to feed to a UsdPreviewSurface... the only primvars currently supported in ARQL are texture coordinates for feeding a UsdUVTexture shader. """ I can not bake textures as my app is meant to work with display colors only. Does anyone have links to official help or information on this? Searching if supporting displayColor as other USD renderers do will be coming eventually.

Hi all, I have a question regarding UsdGeom.PointInstancer: https://graphics.pixar.com/usd/docs/api/class_usd_geom_point_instancer.html schema support on AR Quick Look for USD stages. When packaging the city set example from pixar https://graphics.pixar.com/usd/downloads.html: and using it as a USDZ file ends up in AR Quick Look displaying: No point instancer at all. Prototypes at the origin. I have not been able to find any information regarding support, requirements or plan for UsdGeom.PointInstancer in AR Quick Look or Reality Composer pages. USDView, SideFX Houdini and Autodesk Maya support it without problem, I was hoping to use it for some AR models. Can somebody point me in the right direction for documentation on this, please?

I use usdzaudioimport to embed a simple audio file in my usdz. But in QuickLook (iOS or macOS) the audio is never played. What I've tried : usdzaudioimport ./myfile.usdz ./myfile.usda -a /test audio.mp3 -auralMode notSpatial -playbackMode loopFromStart usdzip myfile.usdz myfile.usda ./0/* where ./0 is the asset folder of myfile.usda I tried with usdc usdzaudioimport ./myfile.usdz ./myfile.usdc -a /test audio.mp3 -auralMode notSpatial -playbackMode loopFromStart usdzip myfile.usdz myfile.usdc ./0/* I tried with usdz without converting to usd(a/c) usdzaudioimport ./myfile.usdz -a /test audio.mp3 -auralMode notSpatial -playbackMode loopFromStart I tried m4a and mp3. I tried the sample cube from Reality Composer by adding my audio.mp3 as behavior at start of scene and exporting in usdz for Quicklook. But none of this solutions worked. I'm not able to play any audio with AR Quick Look usdz file at the start of the scene.
