Hello, I was wondering if we could get the metersPerUnit metadata from a USDZ loaded as an Entity (or even MDLAsset) using Reality Kit? Thanks

RealityKit doesn't appear to support particles. After exporting particles from Blender 4.0.1, in standard .usdz format, the particle system renders correctly in Finder and Reality Converter, but when loaded into and anchored in RealityKit...nothing happens. This appears to be a bug in RealityKit. I tried one or more particle instances and nothing renders.

Hello. I am a student who just studied Swift. It has succeeded in obtaining body joint information through 'skelton.jointLandmarks' from a typical screen, but every time I zoom in, there is a problem that this joint information is not on the human body and moves sideways and downward. From my guess, there may be a problem that the center of the AR screen is not located in the center of the cell phone screen. I've been searching for information for 3 days due to this problem, but I couldn't find a similar case, and I haven't been able to solve it. If there is a case of solving a similar problem, I would appreciate it if you could let me know. Below link is how I zoomed in on the ARView screen. https://stackoverflow.com/questions/64896064/can-i-use-zoom-with-arview Thank you. Below is how I'm currently having trouble.

In visionOS, have many code with 3D attributes (SwiftUI) is adapted from the code in iOS, like: .padding(_:) to .padding3D(_:). In iOS have .offset(x:_, y:_), it only have X and Y, but in visionOS, view is in a 3D scene, so I want offset have Z, but offset can't use Z, so I try offset3D: import SwiftUI //Some View .offset3D(x: Number, y: Number, z: Number) Xcode report an error: Error: No member 'offset3D' So do you now how to use like offset's Modifiers, and can use Z in visionOS.

Hi! Im having an issue creating a PortalComponent on visionOS Im trying to anchor a Portal to a wall or floor anchor and always the portal appears opposite to the anchor. If I use a vertical anchor (wall) the portal appears horizontal on the scene If I use a horizontal anchor (floor) the portal appears vertical on the scene Im tested on xcode 15.1.0 beta 3 15.1.0 beta 2 15.0 beta 8 Any ideas ?? Thank you so much!

https://developer.apple.com/documentation/realitykit/photogrammetrysession/request/modelfile(url:detail:geometry:) if the path given is a file path that contains a .usdz extension, then it will be saved as .usdz, or else if we provide a folder, it will save as OBJ; I tried it, but no use. Right before saving, it shows the folder that will be saved, but after I click on done and check the folder, it's always empty.

I am working on an app where I need to orient a custom view depending on the device heading. I am using ARKit and ARSCNView with the ARGeoTrackingConfiguration in order to overlay my custom view in real world geographic coordinates. I've got a lot of it working, but the heading of my custom view is off. Once the ARSession gets a ARGeoTrackingStatus.State of .localized, I need to be able to get the devices heading (0-360) so that I can orient my view. I'm having trouble figuring out how to do this missing piece. Any help is appreciated.

I have some strange behavior in my app. When I set the position to .zero you can see the sphere normally. But when I change it to any number it doesn't matter which and how small. The Sphere isn't visible or in the view. The RealityView import SwiftUI import RealityKit import RealityKitContent struct TheSphereOfDoomRV: View { @StateObject var viewModel: SphereViewModel = SphereViewModel() let sphere = SphereEntity(radius: 0.25, materials: [SimpleMaterial(color: .red, isMetallic: true)], name: "TheSphere") var body: some View { RealityView { content, attachments in content.add(sphere) } update: { content, attachments in sphere.scale = SIMD3<Float>(x: viewModel.scale, y: viewModel.scale, z: viewModel.scale) } attachments: { VStack { Text("The Sphere of Doom is one of the most powerful Objects. You can interact with him in every way you can imagine ").multilineTextAlignment(.center) Button { } label: { Text("Play Video!") } }.tag("description") }.modifier(GestureModifier()).environmentObject(viewModel) } } SphereEntity: import Foundation import RealityKit import RealityKitContent class SphereEntity: Entity { private let sphere: ModelEntity @MainActor required init() { sphere = ModelEntity() super.init() } init(radius: Float, materials: [Material], name: String) { sphere = ModelEntity(mesh: .generateSphere(radius: radius), materials: materials) sphere.generateCollisionShapes(recursive: false) sphere.components.set(InputTargetComponent()) sphere.components.set(HoverEffectComponent()) sphere.components.set(CollisionComponent(shapes: [.generateSphere(radius: radius)])) sphere.name = name super.init() self.addChild(sphere) self.position = .zero // .init(x: Float, y: Float, z: Float) and [Float, Float, Float] doesn't work ... } }

In full immersive (VR) mode on visionOS, if I want to use compositor services and a custom Metal renderer, can I still get the user’s hands texture so my hands appear as they are in reality? If so, how? If not, is this a valid feature request in the short term? It’s purely for aesthetic reasons. I’d like to see my own hands, even in immersive mode.

Hi, is there a way in visionOS to anchor an entity to the POV via RealityKit? I need an entity which is always fixed to the 'camera'. I'm aware that this is discouraged from a design perspective as it can be visually distracting. In my case though I want to use it to attach a fixed collider entity, so that the camera can collide with objects in the scene. Edit: ARView on iOS has a lot of very useful helper properties and functions like cameraTransform (https://developer.apple.com/documentation/realitykit/arview/cameratransform) How would I get this information on visionOS? RealityViews content does not seem offer anything comparable. An example use case would be that I would like to add an entity to the scene at my users eye-level, basically depending on their height. I found https://developer.apple.com/documentation/realitykit/realityrenderer which has an activeCamera property but so far it's unclear to me in which context RealityRenderer is used and how I could access it. Appreciate any hints, thanks!

Hi Is this possible to have RoomCaptureSession and ARSession together, as we need feature points
