# Mesh Normal Angle node

**Left Toolbar** > **3D Nodes** > ** Mesh Normal Angle Node **

The Mesh Normal Angle node rendeers the angle between the surface normal, and a vector defined in the attributes. The 0 degress angle value is rendered as white, and the 180 degrees value is rendered as black.

## Procedure

### To create a Mesh Normal Angle image:

Load one of more model in the Scene Window.

On the left toolbar choose 3D Nodes > Mesh Normal Angle. >

Drag the Mesh Normal Angle icon into the Node Graph.

## Outputs

**Img**

A monochromatic image where the white values represent and angle of 0 degrees between the normal and the defined vector, and black is an angle of 180 degrees.
