Using ambientIntensity for Reality Kit AR View

Hello,

The light estimates are provided as long as isLightEstimationEnabled is set to true on your configuration, which is the default. This is independent of a renderer, so it works regardless of whether you are using SceneKit, RealityKit, Metal, or something else for rendering.

Here is a small modification to the RealityKit template project, which shows how you can obtain the ambient intensity:

Code Block 
import UIKit
import RealityKit
import ARKit
class ViewController: UIViewController, ARSessionDelegate {
    
    @IBOutlet var arView: ARView!
    
    override func viewDidLoad() {
        super.viewDidLoad()
        
        // Load the "Box" scene from the "Experience" Reality File
        let boxAnchor = try! Experience.loadBox()
        
        // Add the box anchor to the scene
        arView.scene.anchors.append(boxAnchor)
        arView.session.delegate = self
    }
    func session(_ session: ARSession, didUpdate frame: ARFrame) {
        // Do something with the light estimates here.
        print(frame.lightEstimate?.ambientIntensity)
    }
}

Hi gchiste, firstly I would like to thank you for your fast response. I have tried to modify the code as shown by you, however, the program output stated showed that it" Failed to find reflection for buffer clusterIndexTable"

I manage to solve the issue. Thank you!
