The subset of the input geometry to apply the modifications to. Leave this blank to affect all elements.

Blends between the incoming attribute and the output attribute value. A blend of 0 means that no adjustment takes place: the incoming attribute value is the output value. Likewise, a value of 1 will output the adjusted value, ignoring the initial value. Blending can be done either by uniform value (Constant) or by value of the Blend Attribute (when the menu on the right of this parameter is set to Use Attribute).

A float attribute between the range 0 to 1 to use as blend value. This attribute must be present on the appropriate elements (as set by Attribute Class). A blend value of 0 means that no adjustment takes place: the incoming attribute value is the output value. Likewise, a value of 1 will output the adjusted value, ignoring the initial value.

The name of the attribute to create or modify. If the attribute does not exist with the given name, it will be added to the selected Attribute Class.

Specifies which color components will be changed by this node in RGB space. This filter applies as the last step, when the adjustment value is combined with the incoming attribute.

Specifies which color components will be changed by this node in HSV space. This filter applies as the last step, when the adjustment value is combined with the incoming attribute.

The element type for the destination attribute (specified by Attribute Name).

Turns on a set of controls to fine tune the incoming attribute value. All pre-process modifications will take place before the adjustment is applied to the attribute. You can also initialize the attribute if it does not exist in the input as part of the pre-process.

When this checkbox is turned on, all incoming color attributes will be deleted before pre-processing. Use this to remove any conflicting color attributes.

Sets the color for the attribute. Use it to initialize a new attribute or to overwrite any existing attribute value.

Controls how the initial color will be generated. Constant will be the same for all elements in the geometry, while Color Attribute and Float Attribute will copy the given attribute’s values into the destination attribute.

This color will be set for all elements in the geometry, prior to adjustment.

The values of this attribute will be copied into the destination attribute (specified by Attribute Name), prior to any adjustment.

Specifies which color components will be initialized from the color attribute (specified by Color Attribute) based on RGB color model.

The values of this attribute will be copied into the destination attribute (specified by Attribute Name).

Generates a value that will be combined with the incoming attribute value. When this option is turned off, only pre-processing, color-correction, and post-processing will be done.

Specifies how to combine the generated adjustment color with the incoming attribute value. If the target attribute does not exist on the input geometry, all operations will have the same effect.

Specifies how the adjustment value is generated. Constant Value will use the same Value for every element. Random and Noise will generate varying values across each element of the geometry, in which case varying values will be inside a well defined range or selected from a list of specific values. Additionally, you can provide another color attribute to use as the adjustment value for every element. Color Map provides a method to place a texture onto the geometry with existing uv attributes. With Line and Radial you can draw the respective shape in the viewport to vary the color accordingly, while Bounding Box will generate colors based on the relative position of each element inside the geometry’s bounding box.

Sets a uniform color to the whole piece of geometry.

The adjustment value will be generated in the selected range. This parameter governs how this range is specified. You can also provide a list of specific values or multiple ranges by selecting Specific Values, which can be useful to create attribute values representing specific color palettes.

The color space for specifying the range of adjustment values. You can use RGB to constrain the red, green, blue component values or HSV to restrict the adjustment values to a slice of the hue, saturation, value wheel.

When this checkbox is turned on, the given color range will be relative to this color. This is useful if you have a specific color in mind and want small deviations from it.

The minimum and maximum values of the red component.

The minimum and maximum values of the green component.

The minimum and maximum values of the blue component.

The minimum and maximum values of the hue component, which captures the pure color.

The minimum and maximum values of the saturation component, which captures the vibrancy of the color.

The minimum and maximum values of the value component, which captures the brightness.

The intermediate random value will be fed through this ramp to obtain the adjustment color.

This menu contains a set of pre-defined color palettes. Selecting one of these options will populate the list of specific values with four preset colors.

Controls the number of sets of possible adjustment values. Each set can be a single color or consist of multiple related colors (when the menu to the right of the parameter is not set to Constant or Complementary).

The base color for this set.

Controls how the set of colors is derived from the specified base Color.

Samples the given adjustment value with the specified weight. Values with lower Weight will be selected less frequently. When all weights are the same, each adjustment value has the same probability.

Specifies the attribute storing the adjustment value to use.

This is applied as a scaling factor on top of the Adjustment Attribute value.

This value is added to the Adjustment Attribute value (after Gain is applied) to obtain the final adjustment value.

Image file used for lookup. The image file can be done either by a single image file (Image Path) or by providing a string attribute storing the image file path for each element.

Specifies which color components will be used from the selected image file.

A string attribute storing the path to an image file. Each element in the geometry will perform a lookup in its respective image to obtain the adjustment value.

Specifies the color channel for textures that have multiple color planes (for example, diffuse_indirect or N). For ptex images, this specifies the index of the first channel (for example, 0 or 4).

Border color when Decal wrapping is used. This becomes the adjustment value if the image is looked up outside the 0-1 UV range.

The image’s colorspace.

Determines how the image is evaluated when the texture coordinates are outside the range 0 to 1. The options are:

Specifies how the pseudo-random number generator is seeded for each element to produce the adjustment value. Element Number will use the point, primitive, or vertex number depending on Attribute Class. Topology changes on the input geometry can shift element numbers, causing different adjustment values to be used. Custom Attribute lets you provide an integer attribute to make sure the random value is not dependent on element order.

The attribute to use for seeding random number generation.

All generated values depend randomly on this value. Choose a different value if the current seed produces undesirable samples.

The type of noise to generate. Different algorithms give noise with different characteristics.

The node generates values for each element by sampling a noise field at the location specified by this vector attribute on the incoming geometry. If this is P (point position, the default), the points of the geometry will appear to swim through the noise. If you want the noise to “stick” to the points, you can copy the initial point positions into a rest attribute and use that attribute here instead.

Uniform scale of elements in the noise.

Click the Per Component button for separate scales along each axis.

When you turn on the Per Component button, this lets you scale the Element Size separately across each axis.

Offset within the evaluated noise field (added to each axis). If you have the general noise effect you want, but want to get a different set of values for a different look, try changing the offset.

You can animate the noise using an expression such as $T * 0.25 here. This is faster to compute than Animate Noise, but gives the visual effect of “panning” across the noise field, which may or may not be acceptable.

Click the Per Component button for separate additional offsets along each axis.

When you turn on the Per Component button, this lets you add the a separate offset along each axis.
