The following sections describe the properties for each material type in Mudbox.
Mudbox Material
-
-
Specifies the base color of the material. Click the color tile to edit using the window.
Alternatively, this property uses the image and file path for the channel you specify when painting on a model.
-
-
Specifies the color of the specular highlight on the material. Click the color tile to edit using the window.
Alternatively, this property uses the image and file path for the channel you specify when painting on a model.
-
-
Specifies the size of the specular reflection. The lower the value, the smaller the specular highlight. Click the color tile
to edit using the window.
Alternatively, this property uses the image and file path for the channel you specify when painting on a model.
-
-
Specifies the brightness of the material color independent of the scene lighting. Used to simulate the emission of color from
an object independently of other lighting in the scene.
For example, when the Incandescence property is set to RGB (255, 255, 255), the material appears to emit white light, like
a light bulb (even if there are no lights in the scene). The material does not illuminate other models or contribute light
to the scene.
Alternatively, this property uses the image and file path for the channel you specify when painting on a model.
-
-
Lets you control the transparency of the material. By default, the value is white and the material is fully opaque. Setting to a darker color makes the material more transparent. See Paint to apply transparency.
-
-
Specifies how opacity affects lighting effects. There are two options:
-
-
Opacity overrides only the diffuse channel, allowing the transparent surface to continue to show reflections, specularity,
bump, and so on. Use this option to create the effect of a transparent material like glass or clear plastic.
-
-
Opacity overrides all channels, causing the surface to effectively disappear. Use this option to create the effect of a hole
in your model.
-
-
Specifies the file path for the image to be used for the bump map. This map should be based on gray scale values.
This property uses the image and file path for the channel you specify when painting on a model.
-
-
Specifies the file path for the image to be used for the normal map. This map should be based on RGB values.
This property uses the image and file path for the channel you specify when painting on a model.
-
-
Specifies the file path for the image to be used for the reflection mask. This property uses the image and file path for the
channel you specify when painting on a model.
-
-
Controls the height of bumps displaying on the surface when a bump map is applied. Increase the value to make the surface
bumpier. Decrease the value to make the surface smoother.
-
-
Specifies the level of filtering performed on a texture used as a bump map. Values greater than 1.0 produce more filtering,
making the bumps smoother. Values less than 1.0 produce less filtering, making the bumps appear sharper.
-
-
Opacity overrides all channels, causing the surface to effectively disappear.
-
-
Specifies the file path for the image used as a reflection map. An environment is simulated around the model which appears
in the material’s reflection component depending on the value of the property.
NoteIf you create an image-based light, the reflection map image is replaced with the image-based light source image. See
Image Based Light File.
-
-
Controls the visibility of the reflection map. A value of 1 makes the image fully visible and overrides any of the diffuse
color on the model. A value of 0 makes the reflection map invisible.
-
-
Specifies the intensity of the Fresnel glow effect.
-
-
Defines the surface area of the model affected by the Fresnel glow effect. A higher number illuminates only the edges. A lower
number illuminates more of the model with the glow effect.
-
-
Turns on shadows for the material. At least one scene light must also have turned on for shadows to appear on a model.
-
-
Specifies the softness of shadow edges. The softness of shadow edges is also influenced by the property for the shadow-casting light. Keep these two properties in mind if shadow edge artifacts appear.
-
-
Specifies shadow color. Colored shadows help to simulate reflected light on self-shadowing colored surfaces, or in simulating
the shadow produced by transparent, colored surfaces (for example, colored glass). Default is black.
-
-
Specifies the normal map’s coordinate space based on how it was originally extracted. This setting must match the setting
used when the map was originally extracted for the normal map to display properly on the model. (If you are unsure, try each
option in turn and view the results in the ). Options include:
-
-
The coordinate space on a face defined by the normal, tangent, and the binormal.
-
-
Local coordinate space for the model.
-
-
Coordinate space for the 3D scene.
-
-
When is set to this sets how the tangent space vectors are calculated so the extracted map is compatible with other 3D applications (left-handed
or right-handed). This setting is ignored when is set to or . Options are:
-
-
Defaults to a right-handed tangent space setting.
-
-
Defaults to a left-handed tangent space setting.
