False colour mode

I saw that blender has a version of this built in. Is this something that exists in Vray?

When using Filmic Blender’s OCIO with VFB ver1.0, false colors could be displayed.
Filmic Blender cannot be used with VFB ver2.0, but it may be possible to display false colors using OCIO’s Look Transforms.

I came across the false colour options in the “Lighting Analysis” render element. Ill see how that works out.
