Indirect Diffuse Rendering Layer Mask	Specifies the Rendering Layer Mask for indirect diffuse lighting multiplier. If you enable Light Layers, you can use them to decouple Meshes in your Scene from the above multiplier.
Reflection Lighting Multiplier	A multiplier for baked, realtime, custom Reflection Probes and Planar Probes, Screen-Space Reflection, Ray-Traced Reflection, and Sky Reflection. HDRP multiplies the light data from these by this value.
Reflection Rendering Layer Mask	Specifies the Rendering Layer Mask for reflection lighting. If you enable Light Layers, you can use them to decouple Meshes in your Scene from the above multiplier.
Reflection/Planar Probe Intensity Multiplier	A multiplier for baked, realtime, and custom Reflection Probes and Planar Probes. HDRP multiplies the Reflection Probe data by this value.
