Steps to reproduce:
1. Create new Unity project using Universal 3D Template
2. In Project window select “VoxelizeScene.shader” Asset (Packages/com.unity.render-pipelines.core/Editor/Lighting/ProbeVolume/VoxelizeScene.shader)
3. Observe the Inspector window

Actual results: “use of potentially uninitialized variable (rayOrigin) use of potentially uninitialized variable (rayDir)” and “array reference cannot be used as an l-value; not natively addressable, forcing loop to unroll” warnings are thrown in the Inspector window

Expected results: No warnings are thrown in the Inspector window

Reproducible with versions: 6000.3.25f1, 6000.6.3f1, 6000.7.0b2, 7000.0.0a1

Can’t test with versions: 6000.0.84f1 (different warning thrown)

Tested on (OS): macOS 27 (Apple Silicon)
