"Material doesn't have a float or range property '_CullMode'" errors are thrown in the Console when opening Particle Shaders Sample Scene

Unity: ShaderGraph

Open

6.7.X

6.6.X

Steps to reproduce:
1. Create new Unity project using Universal 3D Template
2. Open Package Manager and find Shader Graph Package
3. Select Samples tab in Shader Graph package and import Particle Shaders Sample
4. Open “URP_Particles_Shaders.unity” Scene (Assets > Samples > Shader Graph > 17.7.0 > Particle Shaders > URP_Particles_Shaders.unity)
5. Observe the Console window

Actual results: “Material 'Inter-Regular SDF Material' with Shader 'Samples/SamplesLit_Inter' doesn't have a float or range property '_CullMode’” errors are thrown in the Console when opening Samples Scene

Expected results: No errors are thrown in the Console when opening Samples Scene

Reproducible with versions: 6000.6.0b2 6000.6.0b3, 6000.6.0b4, 6000.7.0a2

Can’t test with versions: 6000.6.0b1, 6000.5.4f1 and lower (No Particle Shaders Sample)

Tested on (OS): Ubuntu 24.04, macOS Tahoe 26.5.1 (M1)
