I am following the [Intermediate Depth Tutorial](https://www.youtube.com/watch?v=FWIhuqrroOQ) and I am finding that the depth map produced by the Depth Manager texture looks worse than the depth map produced when toggling on `ToggleDebugVisualization`. Here are two images showing the difference:

 ![Screenshot_20211111-185037_ArGame](https://us1.discourse-cdn.com/niantic/original/1X/d2c2ef277a862f667b14e3a587a0a99eea836f74.jpeg)

You can note that the first image is able to resolve the doorway behind the bottle, while the depth texture one to the right cannot resolve depth in the distance.

Why do these two versions diverge? What is `ToggleDebugVisualization` doing that makes it superior to the custom approach?

I updated the header to fill in those fields. The most critical thing is the screenshot which I shared which shows the difference.

I wanted to update with a solution. I looked at the existing shaders and augmented my frag function in the shader to look like:

```auto
fixed4 frag (v2f i) : SV_Target
{
     float2 depthUV = float2(i.depth_uv.x / i.depth_uv.z, i.depth_uv.y / i.depth_uv.z);
     float rawDepth = tex2D(_DepthTex, depthUV).r;

     float scaledDepth = rawDepth * (_DepthScaleMax - _DepthScaleMin) + _DepthScaleMin;

     float scaledDisparity = 1.0f / scaledDepth;
     float normDisparity = scaledDisparity / _MaxDisparity;

     return normDisparity;
}

```

And I am setting \_MaxDisparity to 4 and \_DepthScaleMax to 1 and \_DepthScaleMin to 0.

This produces an effect more consistent with `ToggleDebugVisualization`.
