Then before you add the panelEntity you have to set the Position relative the parent entity panelEntity.setPosition((SIMD3(x: attachmentOffsetX, y: attachmentOffsetY, z: attachmentOffsetZ)), relativeTo: parentEntity)

Thank you very much for your comment, so for example when I want to use the SceneReconstructionProvider, I need to have a physical vision pro? Am I right?

Vision Pro can manage nearly 12k resolution per eye. Hope the answer was helpful :)

Then I would recommend to assign a VideoMaterial to the Entity like I mentioned it in this post: https://developer.apple.com/forums/thread/734081

Hello, I am currently working on a framework for the vision pro videoPlayer to make it easier for developers to represent video playback in vision pro. In the next I will publish some open source material, including meta data, resolution, QuickTime, frame rate, UI interface etc. configuration etc. It will be available on my GitHub soon. The performance of the Vision Pro glasses is likely to slightly lag behind of a MacBook Pro M2, but they boast an impressive 12k display for each eye. Best, Pat

I will get in touch if I have some additional information to share. Best, Patrick
