Hi everyone, I’m experiencing a critical issue with USDZ files created in Reality Composer on an iPad 9th Generation (iPadOS 18.3). The files work perfectly on iPads from the 10th Generation onwards and on iPad Pros. However, on older devices like the iPad 9th Generation and older iPhones, QuickLook (file preview) crashes when opening them. This is a major issue because these USDZ files are part of an exhibition where artworks are extended with AR elements via a web page. If some visitors cannot view the 3D content, it significantly impacts the experience. What’s puzzling is that two years ago, we exported USDZ files from Reality Composer, made them available via a website, and they worked flawlessly on all devices, including older iPads and iPhones. Now, with the latest iPadOS, they consistently crash on older devices. Has anyone encountered a similar issue? Are there known limitations with QuickLook on older devices, or is there a way to optimize the USDZ files to prevent crashes? Could this be related to changes in iPadOS or RealityKit? Any advice or workaround would be greatly appreciated! Thanks in advance!

Hi, since RealityKit 4 now supports Blend Shapes I was wondering if there are any workflow or tooling recommendations to bake/export them into a USDZ. Are Blender or Cinema4D capable to do that out of the box? Should we look into NVIDIA omniverse (https://docs.omniverse.nvidia.com/connect/latest/blender/manual.htm) So far this topic seems very sparsely documented and I would appreciate any hints. Thank you!

Looking for help on getting "On Tap" to work inside RCP for my AVP project. I can get it to work when using "on added to scene" but if I switch to "on tap", the audio will not play when attaching the audio to an entity in my scene. I'm using the same entity for the tap gesture that the audio is using for the emitter. Here is my work flow for the "on added to scene" that works correctly to help troubleshoot my non working "on tap". Behaviors: "on added to scene". action - timeline Input target: check mark enabled, allowed all Collision set to default Audio library: source mp3 file Chanel Audio: resource mp3 file above Timeline: Play Audio with mp3 file added This set up in RCP allows my AVP project to launch correctly with audio "on added to scene". But when switching behaviors to "on tap", the audio will no longer play and I can not figure out why. I've tried several different options and nothing works. Please help!
