Toggles the effect of the layer on and off. This duplicates the functionality of toggling visibility in the Shader Tree. When disabled, the layer has no effect on the shading of the scene. However, Modo saves disabled layers with the scene, and they are persistent across Modo sessions.

Inverts the colors (RGB values) for the layer to produce a negative effect.

Affects the blending between different layers of the same effect type. With this, you can stack several layers for different effects.

For more about blending, see Layer Blend Modes.

Changes the transparency of the current layer. If there are layers below this layer in the Shader Tree, reducing this value increasingly reveals the lower layers. Reducing the value always dims the effect of the layer.

Sets the association for the Texture Locator. Most texture layers have a Texture Locator that Modo automatically creates in the Item List. This defines the mapping of the texture (how Modo applies the texture) to the surface. You can specify alternate locators, but this is normally not required. Although you may want multiple texture items to share a single locator.

Defines how a texture/material is applied to a 3D surface. Types vary significantly in their effects. For a guide to each Projection Type see Sorry you didn't find this helpful.

Determines the magnitude of the texture where the cell is most concentrated. This value ramps to the Filler Value. (This is only available when the texture layers effect is set to a non-color attribute.)

Note:  When using Bump or Displacement effects, the Cell Value can be used to adjust the height of the cell.

Determines the color of the texture where the cell is most concentrated. This color ramps to the Filler Color. You only set the Cell Color when the texture layer is set to an effect that requires color. The Alpha value determine how transparent the cell zone is.

Determines the transparency of the cells. This is used with the Cell Color setting.

Note:  You can adjust the Alpha value using the Color Picker.

Determines the magnitude of the texture between the cells. This value ramps to the Filler Value. (This is only available when the texture layers effect is set to a non-color attribute.)

Note:  When using Bump or Displacement effects, the Filler Value can be used to adjust the height of the filler.

Determines the color of the texture between the cells. You only set the Fill Color when the texture layer is set to an effect that requires color.

Determines the transparency of the texture between the cells. This is used with the Filler Color setting.

Specifies the styles of cellular texture and determines how the texture interpolates between its sample points. Click to view examples of the two Type options.
Angular- Creates a somewhat linear interpolation between the sample points in the texture. With the default settings, this results in an effect similar to cobblestone. You can use this to generate effects ranging from lunar surface to craggy skin.
Round- Creates circular spots randomly distributed based on the texture. With the default settings, the texture looks like overlapping, soft-edged dots. By adjusting the settings, you can create effects such as cauliflower or chipped rock.

Determines the maximum scale of the texture's details. If you set this to 100% , the maximum scale of any single detail in the texture is equal to the texture size as set by the texture locator size values. Use this to change the scale of the details of the texture. To set the overall scale of the texture, you modify the texture scale on the Texture Locator tab. Click to view examples of various Cell Width settings.

Controls the amount of gradient falloff around each of the texture details. Setting this value greater than 100% can yield interesting effects. Click to view examples of various Transition Width settings.

Determines the number of virtual layers used by the texture. With this value at 1, Modo disables the Frequency Ratio and the Amplitude Ratio. Adding more than one frequency increases the detail in the procedural texture, which increases computation time. Click to view examples of various Frequencies settings.

You can layer all noise-style procedures to create a fractal effect. Traditionally, to create a fractal you layer a noise pattern multiple times. With each new layer, you increase the frequency (to have smaller details and more of them) and fade the opacity value. When you add a Cellular or Noise texture in Modo, the default settings are not "fractal" in that they use a default Frequencies value of 1 for having only one layer of the procedural effect. Adding multiple frequencies creates a fractal effect and invokes the Frequency Ratio and Amplitude Ratio options.

Determines how much detail to add into each additional application of the noise texture when the Frequencies value is set to a value greater than 1. With a Frequency Ratio value of 2, the second frequency of the texture is twice as high as the first. Visually, this pattern seems to be half as large but with twice as many occurrences. With a Frequencies setting greater than 2, each additional layer of the noise has twice the frequency of the previous layer.

Determines the strength of each additional layer of noise when the Frequencies value is set to a value greater than 1. By default, the setting is .5, which yields an effect where each additional set of frequencies has half the value of the previous one.

Varies the amplitude so as to smooth the outer surface. If you applied the Cellular texture as a displacement, this produces a surface that looks like ridges with smooth tops and ragged valleys. If you invert the texture, the valleys become flat-topped mountains, and the ridges become valleys. Click to view examples of various Smooth Tops settings.

Note:  At the default settings, Cellular produces flattened tops when displaced or bumped due to the clear division of color in the pattern. Consequently, Smooth Tops has little effect on the surface appearance. However, if you increase the Frequencies setting, the surface will roughen and the effect of Smooth Tops will increase.

Varies the brightness or luminosity of each individual cell randomly. Higher numbers increase the differences between cells; lower values have decreased brightness variations. Click to view examples of various Value Variation settings.

Varies the hue (or color) of each individual cell randomly. Higher numbers increase the color differences between cells; lower values have decreased color variations. Click to view examples of various Hue Variation settings.

Varies the color saturation of each individual cell. randomly Higher numbers increase the differences between cells; lower values have decreased saturation variations. Click to view examples of various Saturation Variation settings.

Determines whether Modo favors the Cell Color (or Cell Value) over the Filler Color (or Filler Value) or vice versa. Increasing this value favors the Cell Color (or Cell Value) over the Filler Color (or Filler Value); decreasing the value favors the Filler Color (or Filler Value) over the Cell Color (or Cell Value).
