Below is my function that adds text to an Anchor. In my case the Anchor is an image anchor and I am wondering how to remove the lag when the text is added.
Code Block func addTextToAnchor(anchor: AnchorEntity, text:String, fontSize: CGFloat, color:SimpleMaterial.Color, x: Float, y: Float, z: Float, scale: SIMD3<Float>) { let mesh = MeshResource.generateText( text, extrusionDepth: 0.0, font: .init(descriptor: .init(name: "Consolas", size: fontSize), size: fontSize), containerFrame: .zero, alignment: .center, lineBreakMode: .byWordWrapping) let position = SIMD3<Float>(x,y,z) let material = UnlitMaterial(color: color) let entity = ModelEntity(mesh: mesh, materials: [material]) entity.name = "title" entity.setScale(scale, relativeTo: anchor) anchor.addChild(entity) entity.position = position entity.transform.rotation = simd_quatf(angle: -.pi/2, axis: [1,0,0]) return}
