[Shubi-khanduri]

I am rendering .glb file in my app. I am getting .glb file from the local storage of mobile objects color is completely black IDK what is happening. but when I am getting the same file from asset in Android studio it is working perfectly fine all the colour of object are showing perfectly even if I am getting the year object from URL it is working fine here is but I am doing please help me with this. @ThomasGorisse, or someone else, do you know, how can I fix that? Is it possible? sceneView = findViewById<ARSceneView?>(R.id. sceneView ). apply { lifecycle = [email protected] planeRenderer.isEnabled = true configureSession { session, config -> config. depthMode = when (session.isDepthModeSupported(Config.DepthMode. AUTOMATIC )) { true -> Config.DepthMode. AUTOMATIC

else -> Config.DepthMode. DISABLED

} config. instantPlacementMode = Config.InstantPlacementMode. DISABLED

config. lightEstimationMode = Config.LightEstimationMode. ENVIRONMENTAL_HDR
