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

Inverts the RGB values for the layer producing a negative effect.

Toggles the display of textures in the Camera view to improve readability and performance when working on complex scenes. When this option is disabled, textures are displayed in the Preview Viewport but not in the Camera view. For more information, see Camera Items.

Affects blending between different layers of the same effect type, allowing you to stack several layers for different effects. For more on blending, see Layer Blend Modes.

Changes the transparency of the current layer. Reducing this value increasingly reveals lower layers in the Shader Tree if present, or dims the effect of the layer itself on the surface.

Note:  This property does not function, because AxF Opacity is not yet supported by Modo. Currently, a value above 50% is opaque, and a value of 50% or below makes the layer invisible.

Defines an RGB value for the material's base color that is applied to the surface. When Base Color textures are applied, this parameter acts as a multiplier to the final blended texture values.

Defines an RGB value that tints the specular highlight. When Specular Color textures are applied, this parameter acts as a multiplier to the final blended texture values.

Surfaces can be very different from each other, such as a rubber ball, a plastic cup, or a terracotta brick. These are all seemingly smooth surfaces, but on a microscopic scale their surfaces are very different. The microscopic surface variations have a direct effect on the way the light reflects off of each surface.

The Roughness setting simulates these microscopic differences making surfaces appear more dull or rough, or shiny and smooth. It also affects both the specular highlight as well as ray traced and environmental reflections. When Roughness textures are applied, this parameter acts as a multiplier to the final blended texture values.

Changes the normal vector on the surface affected by the AxF material to accentuate or mask surface distortions generated by the AxF normal texture effect.

At glancing angles (any surface that is near-perpendicular to the direction the camera is facing) many types of surfaces increase their reflectance values. The Fresnel setting increases the specular amount at these glancing angles to produce a physically plausible result.

Specifies the surface transparency. When Alpha textures are applied, this parameter acts as a multiplier to the final blended texture values.

Millions of microscopic scratches on a surface distort highlights and reflections over their surface parallel to the directions of the scratches. The Anisotropy value affects the highlights, simulating this effect.

Anisotropy is controlled by a UV map or further controlled by texture maps when the layer's effect is set to Anisotropy Direction. It can be caused by many man-made processes, such as machining metal and also appears in textiles where shiny threads spread the highlight over a surface.

The UV map dropdown allows you to choose which map determines the anisotropic direction. The U direction (horizontal) defines the direction of the virtual scratches for positive Anisotropy values.

A shading technique giving the illusion that geometry has more detail than it actually does. Without smoothing, geometric faces can appear faceted or flat. The Smoothing amount is set as a percentage so that you have the flexibility to fade in the smoothing amount, or even drive it above 100% or below 0% to create interesting effects.

Note:  At values over 100%, the smoothing effect results in pillowing around each polygon.

Determines which faces should receive smoothing. It sets a maximum angle tolerance between two polygons based on their normals. If the angle between the polygons is greater than the smoothing angle, no smoothing occurs. This is useful so that hard edges, such as cubes, are not smoothed across. The default value of 40° is a good general case value.
