Checker

The Checker texture uses two colors (or values) to create a pattern of alternating squares to resemble a checkerboard. By changing the Transition Width, Bias, and Gain options, you can create a variety of checkered and diamond-like shapes. Additionally, as a procedurally created texture that is mathematically generated at render time, the Checker texture has no fixed resolution and can be magnified nearly infinitely with no visual loss in detail.

Note: For information about adding and working with Shader Tree item layers, see the Shader Tree topic.

Layer Properties

Enable	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.
Invert	Inverts the colors (RGB values) for the layer to produce a negative effect.
Blend Mode	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.
Opacity	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.
Locator	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.
Projection Type	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.
Projection Axis	The texture/material is projected down this axis. This applies to Planar, Cylindrical, Spherical, Cubic, Box, and, Light Probe projection types.

Checker Properties

Checker
Value 1	The magnitude of the texture on the first set of alternating squares. The color ramps to Color 2 based on the Transition Width. When using Bump or Displacement effects, this value describes the height of the first set of squares.
Color 1	The color of the texture on the first set of alternating squares. This color ramps to Color 2 based on the Transition Width. The Alpha value determines the level of transparency.
Alpha	The level of transparency for Color 1. Note: You can adjust the Alpha value using the Color Picker.
Color 2	The color of the texture on the second set of alternating squares.
Value 2	The magnitude of the texture on the first set of alternating squares. The color ramps to Color 1 based on the Transition Width. The Alpha value determines the level of transparency. When using Bump or Displacement effects, this value describes the height of the second set of squares.
Alpha	Determines the level of transparency for Color 2.
Type	Specifies the style for the Checker texture and determines the method of projection. See Type for examples. • Square - Projects the checkered grid from a single axis (which you define in the Texture Locator). • Cubic - Projects the checker grid from all three axes (this may look odd on curved surfaces because the edges interact with each other).
Transition Width	Controls the amount of gradient falloff across each of the texture edges. Driving this value over 100% can yield interesting effects. See Transition Width for examples.
Bias	Determines whether the texture favors Color 1 or Color 2. Increasing this value causes the texture to favor Color 1; decreasing the value favors Color 2. This value is dependent on the Transition Width as it works across the gray tones of the image. See Bias for examples.
Gain	Determines the falloff effect for the texture. This is similar to a gamma control that affects the falloff of the gradient ramp between the two colors. Setting the Gain to 100% creates a sharp falloff effect; setting the value to 0% creates a plateau around the value (or color mid-point) with a sharp falloff at either gradient extreme. This value is dependent on the Transition Width as it works across the gray tones of the image. See Gain for examples.
