Different reflectivity values.
$reflectivity overrides a VTF file's embedded reflectivity value. It tells VRAD how much light should be bounced off the material, without affecting how much it receives.
Note:$reflectivity only affects static lighting.Tip:(only in ) You can use the -reflectivityScale <float> parameter in VRAD to scale the light bounced across the whole map. Default is 1.Usage
To bounce 50% of received light:
$reflectivity "[.5 .5 .5]"
The value is a material vector, representing a RGB color value.
