Section Overview

 

The Environment section of the Substance Lab uses an environment map to realistically light the surface with a variety of effects including environmental reflections and shadows.

 

 

 

Properties

 

 

Property

Description

Use Environment

Specifies whether this section of the Substance Lab is used.  This property must be set to "Yes" for any of the properties that follow to affect the texture.

Environment

Provides the environment map that is used. Clicking this property's "Edit..." button will open the Edit Environment Map dialog.

Depth

Uses the master noise as a height map to make certain areas of your texture look either elevated or indented.

Direct Light

Specifies the brightness of a point light illuminating the surface.  Set this value to zero if you want all illumination to come from the environment map.  This value must be set greater than zero for the results of the Color section to have an effect.

Shadow Strength

Increasing this property darkens any hard shadows cast by the point light.  This property will not have any effect if Global Illumination has been set to the maximum value, or if Depth is too small.

Global Illumination

Increasing this value causes a greater number of light rays to find their way via indirect means to areas of the surface that do not have direct line-of-sight with the point light.  Global Illumination helps to give the surface a more natural appearance.

Ambient Occlusion

This value controls the extent to which indirect light rays form soft shadowing on the surface.

Occlusion Radius

Along with the Ambient Occlusion property, this property also influences any soft shadowing appearing on the surface.  Occlusion Radius will not have any effect if Ambient Occlusion is set to zero.

Enviro Strength

Controls the brightness of environmental reflections.

Enviro Attenuation

Increasing this value causes areas that receive less illumination from the point light to also have less intense environmental reflections.  This property can be used to accentuate shadows since it will cause shadowed areas to also have darker reflections.

Soften Surface

When used in combination with Soften Radius, this property will smooth the elevations of the surface, giving it a more rounded appearance.

Soften Radius

When used in combination with Soften Surface, this property will smooth the elevations of the surface, giving it a more rounded appearance.

Enviro Heading

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

Enviro Pitch

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

Enviro Roll

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