I am testing RealityView on a Mac, and I am having troubles controlling the lighting.
I initially add a red cube, and everything is fine. (see figure 1)
I then activate a skybox with a star field, the star field appears, and then the red cube is only lit by the star field.
Then I deactivate the skybox expecting the original lighting to return, but the cube continues to be lit by the skybox. The background is no longer showing the skybox, but the cube is never lit like it originally was.
Is there a way to return the lighting of the model to the original lighting I had before adding the skybox?
I seem to recall ARView's environment property had both a lighting.resource and a background, but I don't see both of those properties in RealityViewCameraContent's environment.
Sample code for 15.1 Beta (24B5024e), Xcode 16.0 beta (16A5171c)
struct MyRealityView: View {
@Binding var isSwitchOn: Bool
@State private var blueNebulaSkyboxResource: EnvironmentResource?
var body: some View {
RealityView { content in
// Create a red cube 10cm on a side
let mesh = MeshResource.generateBox(size: 0.1)
let simpleMaterial = SimpleMaterial(color: .red, isMetallic: false)
let model = ModelComponent(
mesh: mesh,
materials: [simpleMaterial]
)
let redBoxEntity = Entity()
redBoxEntity.components.set(model)
content.add(redBoxEntity)
// Load skybox
let blueNeb2Name = "BlueNeb2"
blueNebulaSkyboxResource = try? await EnvironmentResource(named: blueNeb2Name)
}
update: { content in
if (blueNebulaSkyboxResource != nil) && (isSwitchOn == true) {
content.environment = .skybox(blueNebulaSkyboxResource!)
}
else {
content.environment = .default
}
}
.realityViewCameraControls(CameraControls.orbit)
}
}
Figure 1 (default lighting before adding the skybox):
Figure 2 (after activating skybox with star field; cube is lit by / reflects skybox):
Figure 3 (removing skybox by setting content.environment to .default, cube still reflects skybox; it is hard to see):
