Toggles the effect of the layer on and off to duplicate 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 photonegative 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 the Layer Blend Modes topic.

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.

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 the need to do so is rare. Still, you may want multiple texture items to share a single locator.

Determines the magnitude of the texture where the cell is most concentrated. This value ramps to the Filler Value. You only use the Cell Value option when you set the texture layer to an effect that does not require color.

Determines the color of the texture where the cell is most concentrated. This color ramps to the Filler Color R. You only use the Cell Color R option when you set the texture layer to an effect that requires color.

Determines the opacity of the Cell Color R value. When the value is below 100%, underlying Shader Tree layers show through attenuating to fully transparent at 0%.

Determines the magnitude between the cells. This value ramps to the Filler Value. You only use the Filler Value option when you set the texture layer to an effect that does not require color.

Determines the color of the texture between the cells. This color ramps to the Filler Color R. You only use the Filler Color R option when you set the texture layer to an effect that requires color.

Determines the opacity of the Filler Color R value. When the value is below 100%, underlying Shader Tree layers show through attenuating to fully transparent at 0%.

Specifies the style of the Poisson Cell texture. These options determine how the texture interpolates between its sample points. Click to view examples of the various Type options.
Angular- Creates a somewhat linear interpolation between the sample points in the texture for an effect similar to cobblestones (with the default setting). You can use this to generate effects ranging from a lunar surface to craggy skin.
Round- Creates circular spots randomly distributed based on the texture. In the default settings, the texture looks like overlapping, soft-edged dots. Adjusting the settings can yield effects ranging from cauliflower to chipped rock. (In the example, these are stretched because of the UV map stretching around the sphere.)

Determines the maximum scale of the texture's features. At 100% the maximum scale of any single detail in the texture is equal to the texture size as set on the Texture Locator tab. To change the scale of the details of the texture, use this value. To set the overall scale of the texture, 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 over 100% can yield interesting effects. Click to view examples of various Transition Width settings.

Controls the cell size by determining the amount of coverage for each cell within the defined grid area. Outside the grid area, the Poisson cells tile infinitely, so increasing the density makes more cells within a single tile. Click to view examples of various Cell Density settings.

Defines the number of cells in a given solution. Each increase doubles the number of cells from the previous level. Click to view examples of various Level settings.

When enabled, allows you to apply a non-planar solid projection on the target surface. Doing this, loses the tiling functionality, and the corners of some cells may intersect with the surface causing non-uniform cells to work more like the regular cellular texture. Normally, the Poisson Cells texture applies a planar-type projection to a surface, where curved glancing angle areas stretch the texture. By applying the texture as a 3D solid, the target surface carves out the texturing from the 3D volume.

Determines whether the texture favors the Cell values or the Filler values. Increasing this value causes the texture to favor the Cell values over the Filler values. Decreasing the value causes Modo to favor the Filler values. Click to view examples of various Brightness settings.

Affects the falloff of the gradient ramp between the Cell and Filler values, which is similar to a gamma control. Setting the Contrast to 100% creates a very sharp falloff effect; setting the value to 0% creates a plateau around the value (or color mid-point) with sharp falloff on either extreme of the gradient. Click to view examples of various Contrast settings.

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

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

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