This page gives information about the Lighting Analysis Render Elements component in V-Ray for Grasshopper.


## **Overview**

---



## **Input Parameters**

---

**Units** *(Integer)* – Chooses which lighting information to be analyzed.

**Luminance** (cd) – Uses the Luminance of the rendered frame in candelas.   
**Illuminance** (lx) – Uses the Illuminance of the rendered frame in lux.

**Range** *(Domain)* – Determines the value range on which the temperature gradient will be mapped to.

**Scale** *(Integer) *– Specifies how values are mapped to colors onto the frame.

**Linear **– The colors are mapped in a linear scale.   
**Logarithmic **– The colors are mapped in a logarithmic scale.

**Display** *(Integer)* – Specifies the analyzed data display mode.

**False Colors** – Fills the frame with a gradient ranging from blue (low values) to red (high values). For the out of range values, it uses respectively black and white.   
**Grid Overlay **– Displays the values at distinct grid points over the frame. They use the same grading colors.

**Grid** *(Integer)* – Specifies the horizontal and vertical space in pixels between two numeric points on the grid.

**Fade** *(Boolean)* – When enabled, it fades the rendered image, so that the grid values would be more visible.

**Legend** *(Boolean)* – When enabled, shows a legend of the false colors at the bottom of the render.


## **Output Parameters**

**Element** *(Generic Data)* – V-Ray Lighting Analysis render element.
