Question PostProcessing ColorGradingRenderer Null Reference Exception

Hi need help on this

I am getting the following error multiple times in Android device (Mostly in GFX: Mali)

NullReferenceException: Object reference not set to an instance of an object.

UnityEngine.Rendering.PostProcessing.ColorGradingRenderer.CheckInternalStripLut () (at <00000000000000000000000000000000>:0)

In Unity Crash and Exception Reports Logs following Error & Warning is shown.

Error: Texture creation failed. 'None' is not supported for Render usage on this platform. Use 'SystemInfo.IsFormatSupported' C# API to check format support.

Warning: 'R16G16B16A16_SFloat' is not supported. RenderTexture::GetTemporary fallbacks to None format on this platform. Use 'SystemInfo.IsFormatSupported' C# API to check format support.

 

Unity's Post Processing Stack effects mostly are not compatible with android devices. Specially most OpenGL ES 2.0 devices can't render post effects of Post Processing Stack

 

This crash happens on "LGE/LG-K430/m253" Android device too.
