ShadowCaster2D API no longer recognizes the 'useRendererSilhouette' property

2D

-

How to reproduce:
1. Create a new 2D Project
2. In the MainScene create a new Empty GameObject
3. Attach the “Shadow Caster 2D” Component to the Empty GameObject
4. Create a new MonoBehaviour Script and attach it to the Empty GameObject
5. In the newly created Script write “using UnityEngine.Rendering.Universal;”
6. In the Start() Method write “GetComponent<ShadowCaster2D>().useRendererSilhouette = true” and Save Changes
7. Enter Play Mode and Select the Empty GameObject
8. Observe the Shadow Caster 2D Component values

Actual result: No changes in the Component Values
Expected result: Casting Source is set to Renderer Silhouette

Reproducible with: 6000.0.71f1, 6000.3.12f1, 6000.4.1f1, 6000.5.0b1, 6000.6.0a1

Reproducible on: macOS 26.3.1 (M3 Pro), Windows 10
Not reproducible on: No other environment tested

    For context, I'd like to point out that when you try to use the 'useRendererSilhouette' property from a script, a warning message tells you:

    'ShadowCaster2D.useRendererSilhouette' is obsolete: 'useRendererSilhouette is deprecated. Use selfShadows instead. #from (2023.1)'

    However the message is mistaken (it was added due to a misunderstanding after a past report of mine), because the property was never deprecated, it is still in the editor as of Unity 6 but with a different name:

    Casting Source → Sprite Renderer

    It does exactly what 'useRendererSilhouette' used to do up until Unity 2023, the only problem is it can't be set from a script anymore, which breaks backward compatibility with projects like mine that used to do so in older versions of Unity.
    And the property 'selfShadows' does a different thing, so it makes no sense to suggest to use that one instead like the warning message currently does: one cannot replace the other.

    The ideal solution to this issue would be to implement APIs that can set all options in the 'Casting Source' drop down menu of the ShadowCaster2D component, since some of them were newly added since Unity 2023, but the APIs weren't aligned to the changed component entirely.
    The minimal solution would be to just let the already existing 'useRendererSilhouette' set 'Casting Source' to 'Sprite Renderer'.
