Issue ID

UUM-97942

Regression

Yes

Transparent objects cannot receive shadows from Point Light when Rendering Path is set to "Deferred" and there is Spot Light in the Scene

-

How to reproduce:
1. Open the attached “IN-93606“ project
2. Open the “SampleScene“ and enter Scene View
3. Observe the result

Expected result: The shadow of the “Sphere” GameObject appears on both the “TransparentPlane“ and “OpaquePlane“ GameObjects
Actual result: Shadow does not appear on the “TransparentPlane“ GameObject.

Reproducible with: 2022.3.58f1, 6000.0.5f1 ,6000.0.38f1, 6000.1.0b6, 6000.2.0a3
Not reproducible with: 6000.0.4f1

Reproducible on: MacOS 15.3 (M4), Windows 10 (by user)
Not reproducible on: No other environments tested

Notes:
- There is a discussion about this issue: [https://discussions.unity.com/t/transparent-objects-cannot-receive-additional-light-shadows-in-deferred-rendering/1587774|https://discussions.unity.com/t/transparent-objects-cannot-receive-additional-light-shadows-in-deferred-rendering/1587774|smart-link]
- If “Spot Light” GameObject is removed from the scene, the shadow works
- If Rendering Path is set to “Forward“, the shadow works
- When zooming in on the “Sphere” GameObject using the mouse, the shadow becomes visible. The zoom distance required for the shadow to appear depends on the position of “Spot Light” in the scene. If the it’s farther from “Sphere”, less zooming is needed for the shadow to appear, if “Spot Light” is closer, more zooming is required
- The issue could not be reproduced when using different types of lights
- Also reproducible in Player
