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 Projection Type Samples.

Specifies the look of the texture distortion, with several noise function types provided:

• Perlin

• Enhanced Perlin

• Gradient

• Value

• Gradient Value

• Impulse

• Lattice

• Bubble

The Seed value is the initial number used when generating the procedural values. Different Seed values produce different random variations and can be useful in changing the texture result, however, you need to use the same Seed value when it is necessary for items to retain the same variations.

This value defines the number of iterations used to create the texture. As this number is increased, turbulence is generated by summing noise, with each summed noise being half the magnitude of the previously summed noise. At low values, the turbulence is smoother, increasing in detail as the number of octaves is increased.

Specifies the amount of corrosion used to create the texture. As this number is increased, more corrosion is introduced into the texture.

Specifies a clip level for the Background Color/Value, truncating values beyond the defined setting. Combined with the Upper Clip value, you can apply this option to extend or contract the total range of values for the texture.

Specifies a clip level for the Foreground Color/Value, truncating values beyond the defined setting. Combined with the Lower Clip value, you can apply this option to extend or contract the total range of values for the texture.

Increasing this value causes the texture to favor the foreground color over the background color, whereas decreasing the value causes the background color to be favored.

Similar to a gamma control that affects the falloff of the gradient ramp between the two color values. Setting the Gain to 100% creates a very sharp falloff effect, whereas setting the value to 0% creates a plateau around the value or color mid-point with sharp falloff on either extreme of the gradient.

When the Output Regions option is enabled, the procedural texture outputs random gray shades per region rather than outlines for tiles, providing a means to add random variety to the procedurally created texture. You can further control the amount of variation using the Regional HSV process layer.

Specifies the Color (or Value) of the texture's background area, which ramps toward the Foreground Color/Value.

Specifies the Alpha transparency of the Background Color.

When enabled, the Background Color area is completely transparent, revealing the shading results of any lower layers.

Specifies the Color (or Value) of the texture's foreground area, which ramps toward the Background Color/Value.

Specifies the Alpha transparency of the Foreground Color.
