Steps to Reproduce:
1. Open the “user’s attached project”
2. Open “SampleScene”
3. Observe the “Cube” GameObject through the Game view

Expected result: The GameObject is colored in beige, brown, and blue details
Actual result: The GameObject is colored white

Reproducible with versions: 2021.3.53f1, 2022.3.63f1, 6000.0.51f1, 6000.1.8f1, 6000.2.0b7
Couldn’t test with versions: 2022.1.0b1 (due to the material being missing from the GameObject)

Reproducible on: macOS 15.5 (M1 Max)
Not reproducible on: Windows 10

Notes:
- Also reproducible in Standalone Player
- The ShaderGraph appears to determine that the shader is not using the EmissionTint parameter. As a result, it does not set up this property during the draw call. However, on macOS, the shader seems to use the EmissionTint parameter, but the property is not properly initialized. This leads to a NaN (Not a Number) value in the shader, causing the rendering issue.
