I can't find a way to download a USDZ at runtime and load it into a Reality View with Reality kit.
As an example, imagine downloading one of the 3D models from this Apple Developer page: https://developer.apple.com/augmented-reality/quick-look/
I think the process should be:
- Download the file from the web and store in temporary storage with the FileManager API
- Load the entity from the temp file location using Entity.init (I believe Entity.load is being deprecated in Swift 6 - throws up compiler warning) - https://developer.apple.com/documentation/realitykit/loading-entities-from-a-file
- Add the entity to content in the Reality View.
I'm doing this at runtime on vision os in the simulator. I can get this to work with textures using slightly different APIs so I think the logic is sound but in that case I'm creating the entity with a mesh and material. Not sure if file size has an effect.
Is there any official guidance or a code sample for this use case?
Hello, there is no sample code that demonstrates this use case, but yes your logic is sound:
- Download the asset with URLSession
- Follow the steps in Loading Entities from a File to load an Entity from the downloaded file.
