Reality_Face Tracking_USDZ_HDRI Question

Why is the HDRi ambient light of a USDZ file different when opened with Reality Face Tracking than when opened with just USDZ in iphone? When I pour the same file into Reality face tracking, it becomes very dark.

I can think of a few reasons why this might be happening:

Reality Face Tracking may be using a different HDRi than the one that's embedded in the USDZ file. The HDRi may be being scaled down when it's imported into Reality. The HDRi may be being adjusted to fit the lighting conditions of the scene.

Can any one help me? please, I also attched the files.

Thank you Xing

Looks to me like you haven't configured EnvironmentTexturing in your ARConfiguration https://developer.apple.com/documentation/arkit/arworldtrackingconfiguration/2977509-environmenttexturing or you've set disableAREnvironmentLighting in the ARViews RenderOptions – https://developer.apple.com/documentation/realitykit/arview/renderoptions-swift.struct/disablearenvironmentlighting
