Issue ID

UUM-77731

Regression

No

Shadows are not rendered smoothly when Shadows Cascade Count is set to 3 or 4

-

Reproduction steps:
1. Open the attached “BugRepro” project
2. Open the “Assets/Scenes/SampleScene.unity“ Scene
3. Zoom in and out in the Scene view
4. Observe the shadows

Expected result: Shadows should transition smoothly without visible artifacts
Actual result: Shadows exhibit blocky artifacts and some parts of the shadows get cut off

Reproducible with: 2021.3.42f1, 2022.3.41f1, 6000.0.14f1

Reproducible on: Windows 11
Not reproducible on: No other environment tested

  1. Resolution Note:

    The example shader in the documentation is for Screen Space Shadows, where shadow coordinates are computed at the vertex. For Cascade Shadows, shadow coordinates should be computed in the fragment shader. See LitForwardPass.hlsl in URP for more details. The following file is the modified shader.

    Also, if the Plane object needs shadow casting, a ShadowCaster pass from Lit.shader can be added to SampleShadows.shader.

    Important to note that the repro project was using the built-in methods and shader example from the URP documentation.
