Directional Lights impact Sprites they should not impact when the GameObjects are on different Rendering Layers

Sep 20, 2024

How to reproduce:
1. Open the “RenderLayerRepro.zip“ project
2. Open the “SampleScene”
3. Select the “Directional Light 2” under “Layer 2“ GameObject in the Hierarchy
4. Change the Intensity value between 0.5 and 1.5 in the Light Component in the Inspector
5. Observe the Scene view

Expected results: The “GO Layer 1“ GameObject lighting level remains the same, while the “GO Layer 2“ GameObject lighting level changes
Actual results: The “GO Layer 1“ GameObject lighting level switches with the “GO Layer 2“ GameObject whenever the light intensity value is higher than the intensity on the “Directional Light 1“

Reproducible in: 2022.3.47f1, 6000.0.20f1
Could not test in: 2021.3.44f1 (Pink materials, unable to reproduce with other materials)

Reproduced on: Windows 11 Pro (23H2), macOS 14.6.1 (M2) (by the reporter)
Not reproduced on: No other environment tested

Resolution Note:

There will be no further updates to the Toon Shader

I just wanted to note that this issue seems to affect others also. For example:

https://discussions.unity.com/t/directional-light-lights-up-underground-mesh-light-layer/923646/2

I really hope there can be a fix for this soon - it seems like it should be a simple thing to fix (just cull directional lights from consideration on materials rendering with no overlapping rendering layer, right?), and it makes it very difficult for us to achieve what we want with our project :( .
