====== Skin Texture Property: rim.exponent ======

Defines the shape of the fading curve for rim light.

|Excepted Data Source|1 component value|
|Data Range|0 or greater|
|Default Value|1|

====== Description ======

The **rim.exponent** texture property defines the shape of the fading curve for rim light expressed as a power function curve.

A value of 1 produces a linear blend between 0 and [[rim_angle|rim.angle]]. This results in a constant intensity change per degree change.

A value of 2 produces a squared curve shape. This results in the intensity changing stronger near [[rim_angle|rim.angle]] value and less near 0 angle. This gives the rim a stronger and defined look.

A value of 0.5 produces a similar squared shape but flipped. This results in the intensity changing stronger near 0 angle and less near [[rim_angle|rim.angle]] value. This gives the rim a softer look.

The source is typically a single component value in the range 0 or greater.

The default value for this texture property is 1.
