Hello. I trained an ObjectTracker.referenceobject using ML, and am using it in RCP. After adding Anchoring to the entity, I set the Target mode to Object and applied the trained model data ObjectTracker.referenceobject. However, there is no tracking effect after building for VisionPro. Are any permissions required? What should I do?

Hello, I have multiple models that use different shaders to create hover effects. How can we make one of these models hover while the other models also switch to hover state?

Why do I play an AIVU 180 degree video, which has always been able to play smoothly, and then suddenly played too laggy recently? The video is embedded locally, without network factors, and the video parameters and program code have not changed at all. I also tested playing videos around 400m in size, and the CPU displayed 400-500%, but it was very smooth. When playing a video of 1G or so, the clip is 20-30%, but it is too laggy. Except for the different video duration, other parameters are the same. May I ask what caused the lag.

My project environment must be in mixed mode. When I use code to control OpacityComponent to fade Entity in and out, occasionally the gradient model outline area will appear with video penetration. What is the reason and how can it be resolved?

There is a UI panel with Attachment added in my scene. There are other models in the scene, and when the model fades in using OpacityComponent, the UI panel incorrectly displays the outline of the model, as shown in the red box in the picture. The model fade in code is like this: public func FadeInEntity( entity:Entity, duration: TimeInterval = 1.0, completion: (() -> Void)? = nil ) { entity.stopAllAnimations() if entity.components[OpacityComponent.self] == nil { entity.components.set(OpacityComponent(opacity: 0)) } else{ entity.components[OpacityComponent.self]?.opacity = 0 } EnableEntity(entity: entity) let action = FromToByAction<Float>( from: 0, to: 1, timing: .easeInOut ) do { let anim = try AnimationResource.makeActionAnimation( for: action, duration: duration, bindTarget: .opacity ) entity.playAnimation(anim) DispatchQueue.main.asyncAfter(deadline: .now() + duration) { completion?() } } catch { completion?() } }

Hello, everyone. How to paste a mov transparent video of a generation channel on a model in RCP? In addition, how to paste a video with a black background on the model and remove the black part to make it transparent.

The particle system produced in RCP, when the VisionPro knob is long pressed to reset, the motion direction of the Motion parameter is misaligned. Is there a way to solve it?

May I ask if there is a complete source code project for this instructional video that needs to be learned. Work with Reality Composer Pro content in Xcode

How to make RCP start playing Timeline from scratch when receiving OnNotification. At present, I have only played the timeline once after receiving the OnNotification, and cannot replay it again after receiving the OnNotification again.

This is my animation playback method, there are two issues. 1.How to make the animation stop until the last frame after playing once when isLoop=false? When I specify the name of an animClipName animation clip, I cannot play the corresponding animation name. How do I set it up? The animation structure is shown in the figure. PlayAnim(animEntityName: "Book",animClipName: "Open",isLoop: false) private func PlayAnim(animEntityName: String,animClipName: String? = nil,isLoop:Bool = true,transitionDuration: Double = 0.5){ guard let XR = XR else { return } guard let entity = XR.findEntity(named: animEntityName) else { return } let availableAnims = entity.availableAnimations let targetAnimResource: AnimationResource? if let clipName = animClipName { targetAnimResource = availableAnims.first(where: { $0.name == clipName }) } else { targetAnimResource = availableAnims.first } guard let animClip = targetAnimResource else { return } let anim = animClip.repeat(count: isLoop ? 0 : 1) entity.playAnimation(anim,transitionDuration: transitionDuration) }

attachments: { Attachment(id: "UI_Book_01") { Button { print("Tap...") } label: { Text("Tap me") .padding() .background(.ultraThinMaterial) }.hoverEffect { effect, isActive, _ in if isActive { print("hover...") //Unable to trigger } return effect } } }
