Question Massive breaking changes in URP 14.0.6 in Unity 2022.2.11

Hi,

I have two major issues in the latest Unity 2022.2.11 with URP 14.0.6

I get an error about positionOS

Shader error in 'Hidden/kMotion/MotionBlur': invalid subscript 'positionOS' at line 44 (on d3d11)

Code (csharp):

1.  
2. Shader "Hidden/kMotion/MotionBlur"
3. {
4.     Properties
5.     {
6.         _MainTex("Source", 2D) = "white" {}
7.     }

37.         UNITY_INITIALIZE_VERTEX_OUTPUT_STEREO(output);
38.         output.positionCS = TransformObjectToHClip(input.positionOS.xyz);
39.         float4 projPos = output.positionCS * 0.5;
40.         projPos.xy = projPos.xy + projPos.w;
41.         output.uv.xy = input.uv;
42.         output.uv.zw = projPos.xy;
43.         return output;
44.     }
45.  

and also an error about sampler_MainLightShadowmapTexture

"Shader error in 'Unlit/VolumeFogSRP_FORWARD_URP': undeclared identifier 'sampler_MainLightShadowmapTexture' at line 500 (on d3d11)"

This was declared in Shadows.hlsl in previous versions.

I checked the URP Shadows.hlsl file and instead declares "sampler_LinearClampCompare".
Replaceing in my shader the "sampler_MainLightShadowmapTexture" with the declared "sampler_LinearClampCompare" solves the issue.

Those are massive breaking changes, is it correct to be like this, or is some bug in the new version ?

Also the latest Graphics github does not have those massively breaking changes

Thanks in advance for any help on this matter

 

I also have the exact same problem.
It seems that sampler_LinearClampCompare does solve the issue but what happend to sampler_MainLightShadowmapTexture?

 

I just replace my shadow sampler with the "MainLightRealtimeShadow" func which is provided in shadows.hlsl, and it works fine for my project.

 

Thanks for the solution!

Really weird what Unity is doing. It also broke their water system in Boat Attack sample.
