Trouble loading ModelEntity from RealityKitContent package

Hi,

I'm working on a simple visionOS app and I'm testing on device.

For one part of the app, I load an object in and place it on the user's hand. If I use a primitive shape, like a sphere or cylinder, this works fine. However, now I'm trying to load a an object from my RealityKitContent package. But everytime I try this, I get a an error message, resourceNotFound("Stone"), where "Stone" is one of my usda scenes.

This is what the guts of my function looks like that should return a ModelEntity:

do {
            
       let entity = try await ModelEntity(named: "Stone", in: realityKitContentBundle)
       entity.generateCollisionShapes(recursive: true)
        return entity
 } catch {
        print("Error \(error)")
 }

I can see the "Stone" in my Xcode sidebar as part of the RealityKitContent package and inside that scene, there is a simple sphere, but alas I always get this in the Xcode console, "Error resourceNotFound("Stone")"

I'm probably doing something pretty silly, hopefully it's obvious to someone else.

Thanks for the help.

Try this. If it doesn't work, it should at least spit out some useful error information in the console at run time.

            do {
                let entity = try await Entity(named: "Stone", in: realityKitContentBundle)
                content.add(entity)
                
            } catch {
                print("Error loading stone model: \(error.localizedDescription)")
            }

Thanks for the reply. I'm using this slight code variation, because I really need a ModelEntity for physics stuff instantiated:

 let entity = try await ModelEntity(named: "Stone", in: realityKitContentBundle)

And this is the error I get:

Error Failed to find resource with name "Stone" in bundle

Any other thoughts?

Hi! I stumbled upon the same problem, and I think I've found a solution: In the Model File Inspector (on the right side when you click on the model file), there's a 'Target Membership' section. Just check the box for your application there. That's it!
