Regression

Yes

[WebGL] shadows with soft shadows setting enabled have pixelated edges in WebGL build

WebGL

-

How to reproduce:
1. Open the project from the attached file "1240932.zip"
2. In the Hierarchy select "Directional Light" GameObject and in the Inspector set Shadow Type to Soft Shadows
3. Go to File -> Build and Run
4. Inspect the shadow in the WebGL build

Expected result: shadow has smooth edges
Actual result: shadow edges are pixelated

Reproducible with: 2020.1.0a4, 2020.1.0b8, 2020.2.0a9
Not reproducible with: 2018.4.22f1, 2019.3.12f1, 2020.1.0a3

Notes:
- Not reproducible on Windows or Mac builds
- Reproducible on Built-in pipeline and URP
- Tested with these URP versions: 4.10.0-preview, 7.0.1, 7.1.8, 7.3.1, 8.0.1, 8.1.0, 9.0.0-preview.14
- Default quality settings are the same for Windows and WebGL

  1. Resolution Note (fix version 2020.2):

    WebGL 2 has mixed support for depth texture interpolation, as used by soft shadow filtering. I added a work-around to allow soft shadows to work.

    Can we expect a backport to 2020.1 soon? There's zero value to have this fix in an alpha version only.

    Curious to see if there is any further progress on this. I am still getting the problem in webgl builds produced with 2020.1.4f1 and 2020.2.0b8.

    Hello, it's solved for me. I was just using the wrong pipeline asset (high instead of medium). The WebGL build only uses the medium asset by default and there the shadows werent set to soft.

    Hi there. Has there been any progress on this issue? I'm experiencing the same with a webgl build out of 2020.1.0b7. Is there a later release i can Upgrade to, that doesn't have this problem? Cheers
