I'm Using Unity and ARCore. Problem is, when i use the gamma color space the AR Camera works fine. but, using the Linear Color Space It creates a white overlay on top of the AR camera. I must have to use the Linear Color Space. What should i do ?

Ok, Solved this. I've to make a custom shader for the arcamera backgound.
Create(or copy the arbackground material) a material and assign the bellow shader and replace with ar material.

Shader "ARCore/ARBackground(Linear)"

{

    Properties {

        _MainTex ("Texture", 2D) = "white" {}

        _UvTopLeftRight ("UV of top corners", Vector) = (0, 1, 1, 1)

        _UvBottomLeftRight ("UV of bottom corners", Vector) = (0 , 0, 1, 0) 

    }



    // For GLES3

    SubShader

    {

        Pass

        {

            ZWrite Off
