# token preliminary:anchoring:type = "plane" Hi! I created manually USDZ with one cube to anchoring on wall (vertical plane) I wonder if this more insecure format is perhaps now specifically disallowed. The difference between Apple's working QuickLook examples and the above site, is that whilst the official static model examples all point to a pre-generated USDZ file, the ThreeJS example generates the USDZ on the fly in Javascript code, and populates the link with a Javascript Blob object. I'm trying to figure out if this is a visionOS safari bug or a limitation of the OS itself, and was wondering if anybody else has hit the same problem/heard anything about Safari Quicklook params changing on visionOS. Open the visionOS simulator, and load the same site in Safari. The model loads into QuickLook as expected. Open the above example page in iOS and click the QuickLook icon. This works as expected on iOS and iPadOS, but silently fails to load in the visionOS simulator in Xcode 15 beta 2. I've got a website that dynamically generates a USDZ file and adds that to the webpage as described in the Apple docs here. Please let me know if you require any additional information from my end. I am reaching out to request assistance in resolving this issue, or if this is indeed a bug, to bring it to your attention for further investigation. However, when I then tried to open this SCN file with SceneEditor and export it to USD using the application's menu, Xcode crashed. The export process succeeded, however, when I tried to play the resulting USD file, none of the animations were present.įurthermore, I attempted a workaround by first exporting to an SCN file, which also succeeded. Given the nature of the error, I suspect there may be an issue with SceneKit's handling of blend shape animations when converting to USD.Īs a test, I removed the blend shape animations, keeping only the position animations, and attempted to export again. The error that I receive is as follows:Ģ SceneKit 0x1b19d3528 USDKitConverter::processBlendShapeAnimation(USKNode*, CAAnimation*, std::_1::vector>&, std::_1::vector>, std::_1::allocator>&) + 484 When I attempt to export the scene to a "USD" type file, the export process fails. In my application, I have programmatically added various animations to my scene, which include position, blend shape, and rotation animations. I am writing to report an issue that I have been encountering while developing an iOS game using SceneKit.
