Weight Map Image

The 'Weight Map' texture uses a vertex Weight Map to blend between two values or colors (with alpha). The Value or Color 1 setting will appear anywhere the vertex map value is '0'. The Value or Color 2 setting will appear anywhere the vertex map value is '1'. There will be a blend between the primary and secondary value or color settings where the vertex map moves from 0 to 100. The gradient can be modified by the 'Bias' and 'Gain' controls. This texture is especially useful as a layer or group mask.
For information regarding adding and working with Shader Tree Items Layers, please reference the Shader Tree page of the documentation.

Weight Texture PanelLayer--

Enable: Toggles the effect of the layer on and off, duplicating the functionality of toggling visibility in the Shader Tree. When un-checked (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.

Invert: Inverts the weight values for the layer producing a negative effect.

Blend Mode: Affects blending between different layers of the same effect type, allowing user the ability to stack several layers for different effects. For more on blending, please reference the 'Blend Modes' page of the documentation.

Opacity: Changes the transparency of the current layer. Reducing this values will increasingly reveal lower layers in the shader tree if present, or dim the effect of the layer itself on the surface.

Weight Map Texture--

Color 1: Determines the color of the texture for Weight values of 0, ramping toward Color 2 based on the weight map itself. This setting only applies to surfaces that require a color value. The 'Alpha' value determines the level of transparency for the Color 1 zone.

Value 1: Determines the value of the texture for Weight values of 0, ramping toward Value 2 based on the weight map itself. This control is only active when the texture layers Effect is set to a non-color attribute.

Color 2: Determines the color of the texture for Weight values of '1'. This setting only applies to surfaces that require a color value. The 'Alpha' value determines the level of transparency for the Color 2 zone.

Value 2: Determines the value of the texture for Weight values of 1. This control is only active when the texture layers Effect is set to a non-color attribute.

Vertex Map: Users may use this drop down menu to choose an existing Weight Map or Vertex Color Map.

Bias: The bias control will cause the texture to favor either the primary or secondary value or color. By increasing the bias more of the color/value1 will appear while decreasing the number will force more of the color/value 2 into the gradient blend.

Gain: The Gain setting is similar to a contrast control that effects the falloff of the gradient ramp between the Color/Value 1 and Color/Value 2. Setting the Gain to 100% will create a very sharp contrast whereas setting the value to 0% would reduce the contrast between the two to almost imperceptible amount.
