Edit Environment Map Master Controls

The Master Controls section of the Edit Environment Map dialog contains a number of properties for tweaking the environment map.

 

 

Property

Description

Exposure

Brightens or darkens the environment map in a way that imitates changing the exposure setting on a camera.

Gamma

Modifies the relative brightness of different parts of the image using a gamma curve.  This property can help simulate the response to light that different cameras and display devices have.

Heading

Rotates the environment map as if a person observing the environment turned his head right or left.

Pitch

Rotates the environment map as if a person observing it looked up or down.

Roll

Rotates the environment map as if a person observing it tilted his head sideways.

Filter

Diffuses the environment map using one of the following techniques:

 

None

The environment map is not diffused.

Diffuse

Diffuses the environment map so that when it is reflected off a surface it will create the impression of a diffuse material.  This option causes a Radius property to appear that controls the degree to which light is diverted from its regular path.

Scatter

Partially diffuses the environment map so that when it is reflected off a surface it will create the impression of a material that partially scatters light.  This option has a Radius property that controls the degree to which light is diverted from its regular path, and a Strength property that controls the amount of light that gets diverted.

Anisotropic

Diffuses an environment map with individual controls for the degree of horizontal and vertical diffusion.
