Resolved TransformWorldToShadowCoord function in HDRP?

I am trying to port the custom lighting nodes in LWRP to HDRP, but this line throws an error:
float4 shadowCoord = TransformWorldToShadowCoord(WorldPos);

I cannot find the HLSL file in the API containing this function. If someone can point me to the location in the API, then I can include that file.

Thank you.

 

lwrp --> Shadows.hlsl

 

Thank you, larsbertram1.
I am looking for the equivalent file in hdrp, so I can port the custom lighting to hdrp.

 

Hello, all the source code of HDRP is available on github here: https://github.com/Unity-Technologies/ScriptableRenderPipeline
And the function you're looking for is here: https://github.com/Unity-Technologi...e/Lighting/Shadow/HDShadowAlgorithms.hlsl#L47

 

Thank you, meadjix!

 

Hello,
First excuse me for the revival of this thread but I'm facing the same error. The link doesn't exist anymore, do you have the function's name or another link, I couldn't find on the net,
Thank you

 

The SRP repository has been moved to Graphics, here's the new link:

Hi,

I can't find the function inside the file that you send...

 

Code (CSharp):

1. float4 EvalShadow_WorldToShadow(HDShadowData sd, float3 positionWS, bool perspProj)
2. {
3.     // Note: Due to high VGRP load we can't use the whole view projection matrix, instead we reconstruct it from
4.     // rotation, position and projection vectors (projection and position are stored in SGPR)
5. #if 0
6.     return mul(viewProjection, float4(positionWS, 1));
7. #else
8.  
9.     if(perspProj)
10.     {
11.         positionWS = positionWS - sd.pos;
12.         float3x3 view = { sd.rot0, sd.rot1, sd.rot2 };
13.         positionWS = mul(view, positionWS);
14.     }
15.     else
16.     {
17.         float3x4 view;
18.         view[0] = float4(sd.rot0, sd.pos.x);
19.         view[1] = float4(sd.rot1, sd.pos.y);
20.         view[2] = float4(sd.rot2, sd.pos.z);
21.         positionWS = mul(view, float4(positionWS, 1.0)).xyz;
22.     }
23.  
24.     float4x4 proj;
25.     proj = 0.0;
26.     proj._m00 = sd.proj[0];
27.     proj._m11 = sd.proj[1];
28.     proj._m22 = sd.proj[2];
29.     proj._m23 = sd.proj[3];
30.     if(perspProj)
31.         proj._m32 = -1.0;
32.     else
33.         proj._m33 = 1.0;
34.  
35.     return mul(proj, float4(positionWS, 1.0));
36. #endif
37. }
38.  

 

Hello! I'm getting an undefined punctual shadow filter algorithm error after including the shadow hlsl file. Do you have any tips on how to get rid of this error?

 

Sorry for ressurecting this once more.. I am a bit lost here..
The method "TransformWorldToShadowCoord" exist in shadow.hlsl (URP) with exactly the same signature.

But in HDShadowAlgorithms the method "EvalShadow_WorldToShadow" has a different signature (besides the different name).

So, how is suppose to "translate" one thing (URP) in the another (HDRP)?

 

Hello so I'm using HDRP and yeah I'm also having this issue with TransformWorldToShadowCoord, using EvalShadow_WorldToShadow gives another error.

Shader error in 'Master': undeclared identifier 'TransformWorldToShadowCoord' at Assets/GetLighting.hlsl(12) (on d3d11)

Shader error in 'Master': 'EvalShadow_WorldToShadow': cannot implicitly convert from 'float3' to 'struct HDShadowData' at Assets/GetLighting.hlsl(12) (on d3d11)

not really sure how to proceed with this.

 

I've got the same issue. I can see I need to use

EvalShadow_WorldToShadow

but how do I set up the

HDShadowData

for the function to work?

It would be suer helpful for some actual examples

 

Bump, stuck on the same issue

 

nothing yet? i really need this for our project
