Light Estimate error

Questions
1

i am getting below error

Uncaught (in promise) DOMException: Failed to execute ‘requestLightProbe’ on ‘XRSession’: Light estimation feature is not supported.

Here is the code i am using to enter XRsession.

await xrHelper.baseExperience.enterXRAsync(“immersive-ar”, “local-floor”, xrHelper.baseExperience.renderTarget);

The error report tells you exactly what you need to know - light estimation is not supported in your browser. Not sure what browser you are trying to use. check this page for more details:

you example is working

https://playground.babylonjs.com/#NAZYHG#5 is working fine , i am using One Plus Nord.

i am assuming the way i implemented the code might have issues

var xrHelper = await currentScene.createDefaultXRExperienceAsync({ disableDefaultUI: true, disableTeleportation: true,optionalFeatures: true, pointerSelectionOptions: {
enablePointerSelectionOnAllControllers: true
}})

  1. const fm = xrHelper.baseExperience.featuresManager;
    xrHitTestModule = fm.enableFeature(WebXRHitTest, “latest”);

       // enable other features...
   //anchors = fm.enableFeature(WebXRAnchorSystem, 'latest');
   //console.log(anchors)

    1.  var  xrSession = await xrHelper.baseExperience.enterXRAsync("immersive-ar", "unbounded", xrHelper.baseExperience.renderTarget);

  2. then i am loading the model

  3. const le = xrHelper.baseExperience.featuresManager.enableFeature(BABYLON.WebXRFeatureName.LIGHT_ESTIMATION, ‘latest’, {
    // cubeMapPollInterval: 1000,
    createDirectionalLightSource: true,
    // reflectionFormat: ‘srgba8’,
    // disableCubeMapReflection: true
    });

at this point i am getting error.

is there some wrong i am doing…

you need to enable the feature before starting the session, otherwise the feature will not be available. I would personally also remove the optionalFeatures: true, but that’s not a must.

One more question i have,

how to enable or disable in run time light estimation.

6

WebXR features cannot be turned off during runtime. You can disable the light generated, if that helps.

can you disable the light generated…

why, yes, it is a babylon light after all :slight_smile:
