Value Components

Value components are numerical values you use to set the intensity of a channel. Values can only be used in the Value, Optics, or Volume channels.

A value is indicated by either the numerical field in the left side of the channel in the Material Grid, or the slider that extends out from the channel. The sliders let you quickly set the value of a channel, and the numeric field shows the current setting.

Values can be used with textures. In this case the value sets how much of the texture is applied to the channel. For example, if you use an orange-colored texture to set the Diffuse Color channel, the value would indicate how much of the texture color is used as the Diffuse Color.

A value of 100 means that all the texture information is used in the channel; a value of 0 means that none of the texture is used.

Not all channels use values. The Color channels only use colors or textures. The Refraction channel can only be set with a value.

To use a value as a component, in the Materials Lab, drag the slider next to the channel whose value you want to set. As you drag, the numerical value appears in the number field. The Bump Height channel let you set negative values.

You can also click in the numeric field and manually enter a value.
