Regression

Yes

Fog removes shadows and lighting from the scene when enabled via script

-

Reproduction steps:

1. Open the attached project “IN-90253“
2. Build&Run the Player
3. Observe the result in the Player

Expected result: The fog is applied naturally, view distance is reduced
Actual result: The fog removes all shadows and light sources from all objects in the world no matter the distance, and paints all objects in a color of the fog

Reproducible in: 6000.1.0a2, 6000.1.0a7
Not reproducible in: 2021.3.46f1, 2022.3.54f1, 6000.0.30f1, 6000.1.0a1

Reproducible on: macOS 14.6.1 (M1 Pro), Windows 10
Not reproducible on: No other environments tested

Notes:

  • Reproducible only when fog is enabled from a script (in the project, the fog is enabled in “Start“ method of “CamController“ script). Enabling fog through Window → Rendering → Lighting in Environment tab does not produce the actual result
  • Setting fog density doesn’t change the behaviour
  • Reproducible only in Player

  1. Resolution Note:

    Hello

    Starting in 6.1, Fog cannot be configured at runtime by default. This is a tradeoff we've made in order to reduce shader variants and build times.

    If you wish to change this behavior, you can set k_DynamicBranchFogKeyword to 1 in the URP config package (this is not documented yet). More info on the config package here: https://docs.unity3d.com/6000.0/Documentation/Manual/urp/URP-Config-Package.html

    Let me know if you're still experience problems with this.
