Enabled – When enabled, the render element appears in the V-Ray Virtual Frame Buffer.
Filename suffix – The text added to the end of the rendered file, when saved as a separate file (e.g. myrender.specular.vrimg)
Quantity – Choose which lighting information to be analysed.
Illuminance (lx) – Uses the Illuminance of the rendered frame in lux.

False colors – Fills the frame with a gradient ranging from blue (low values) to red (high values). For the out of range values uses respectively black and white.
Grid overlay – Displays the values at distinct grid points over the frame. They use the same grading colors.
Grid horizontal/vertical spacing – Specifies the horizontal/vertical space in pixels between two numeric points on the grid.
