What Reflection Probe setting will create a shiny reflective surface on a hallway's Mesh Renderer?

The setting that creates a shiny reflective surface on a hallway's Mesh Renderer is the choice that allows for blending reflections from multiple sources, including the environment. "Blend Probes and Skybox" enables the reflection probe to incorporate a wider range of lighting information from both pre-computed probes and the skybox. This results in more dynamic and varied reflections, as the surface will reflect not only its immediate surroundings but also the broader environment, enhancing the shiny appearance of the materials used in the hallway.

In contrast, the other options do not provide the same level of reflective quality. A "Single Probe" setting would only utilize one reflection probe without considering surrounding elements. The "Static" setting relates more to the object being unchangeable during gameplay, having no direct influence on reflections. "Box Projection" is useful for specific types of probes but does not offer the comprehensive blending capability that leads to the desired high-quality reflections across various surfaces.
