Reproductions steps:
1. Open the attached “IN-109628.zip” project
2. Open the “Outdoors Scene”
3. From the Project Window, select the “Test.mat” Material
4. In the Inspector, find the “EmissionColor” property
5. Try to modify its color value
6. Observe the color and the Cube in the the Scene
Expected result: The “EmissionColor” property changes to whatever color was selected and remains both in Inspector and on GameObjects
Actual result: The "EmissionColor" exposed property reverts to a (255,255,255) white color
Reproducible with: 2023.1.0a1, 6000.0.54f1, 6000.1.13f1, 6000.2.0b12, 6000.3.0a3
Reproducible on: Windows 11
Not reproducible on: No other environment tested
Workaround: Change the property name in the ShaderGraph to not be exactly “EmissionColor”
Notes:
- This is likely due to "_EmissionColor" being an internal value that is used in the underlying shader
- Does not reproduce with URP or BuiltIn Shaders
