Decals Illumination PropertyManager

The Decals Illumination PropertyManager sets lighting properties for a decal.

To display this PropertyManager, apply a decal to a model. In the Decals PropertyManager, click the Illumination tab.


  Dynamic Help Displays pop-up tooltips for each property.
  Use Underlying Appearance Applies the illumination settings from the appearance under the decal to the decal. When cleared, this option sets the illumination for the decal directly and enables the remaining options in this PropertyManager.
  Diffuse Amount Controls intensity of light on a surface. A higher value makes the surface appear brighter.
  Specular Amount Controls the intensity of highlights, making the surface appear shinier. A lower value reduces highlights. Dependencies: Specular Spread must be greater than 0. At least one directional, spot, or point light must illuminate the model and be enabled in PhotoView.
  Specular Color Controls the color of reflected highlights within the specular component. Double-click to select color. Dependencies: Specular Spread and Specular Amount must be greater than 0. At least one directional, spot, or point light must illuminate the model and be enabled in PhotoView.
  Specular Spread Controls the blurriness of reflections on a surface, making the surface appear rough or smooth. Higher values make highlights larger and softer. Dependencies: Specular Amount must be greater than 0. Specular Color must not be black. At least one directional, spot, or point light must illuminate the model and be enabled in PhotoView. When Blurry Reflections is disabled, affects reflections of physical lights only. When Blurry Reflections is enabled, includes environmental and self-reflections.
  Reflection Amount Controls the reflectivity of a surface, on a scale of 0 to 1. If set to 0, no reflections are visible. If set to 1, the surface simulates a perfect mirror.
  Blurry Reflections Enables blurring of reflections on surfaces. The level of blurring is controlled by Specular Spread. When Specular Spread is 0, no blurring occurs. Dependencies: Specular Spread and Reflection Amount must be greater than 0.
  Transparent Amount Controls the degree to which light can pass through a surface. Lower values increase the opacity; 0 is completely opaque. Higher values increase the transparency; 100 is completely transparent.

PhotoView Illumination

These options are enabled when PhotoView 360 is added in.

  Index of Refraction

Available when Transparent Amount is greater than 0. Determines how far a light ray bends when it travels through a material.

A higher value increases distortion in refracted items. Set to 1.0 to simulate light traveling through a vacuum; the rays do not bend. A value of 1.333 approximates the distortion caused by light traveling through water, assuming the surface has some transparency.

  Refraction Roughness Available when Transparent Amount is greater than 0. Determines the level of blurriness of items viewed through the surface. Set to 0 to disable the effect. Increase the value to simulate frosted glass, for which items close to the surface are clear and items further away have softened edges and details.
  Luminous Intensity Controls the brightness emitted from the surface. Higher values increase the brightness.
  Double Sided
In some cases, double-sided surfaces can cause rendering errors. Use sparingly.
