Color Balance

Corrects the color or intensity of a texture.

Default Color

If you map a texture to a material in such a way that it that does not cover the entire surface, the file node’s Default Color shows through. To select a different color, click the color bar to open the Color Chooser. To change the texture’s coverage, use the placement options.

Color Gain

Scaling factor applied to the texture’s outColor channel. For example, you can color-correct a texture that appears too green by setting the Color Gain to a shade of blue.The default color is white (no effect).

Color Offset

Offset factor applied to the texture’s outColor channel. For example, you can brighten a texture that appears too dark by setting the Color Offset to a shade of grey. The default color is black (no effect).

Alpha Gain

Only has an effect if the texture is used as a bump or displacement. Scaling factor applied to the texture’s outAlpha channel. The default value is 1 (no effect).

Alpha Offset

Only has an effect if the texture is used as a bump or displacement. Offset factor applied to the texture’s outAlpha channel. For example, if the Alpha Gain value is -1 and the Alpha Offset value is 1, the outAlpha channel is inverted. The default value is 0 (no effect).

Alpha Is Luminance

Off by default. The alpha (mask) output depends on the luminance of the color channels. Bright areas of the texture are more opaque when compositing, and dark areas are more transparent.

Note

You cannot use Alpha Is Luminance for Cloth, Ramp, or Stencil textures.

Effects

Filter

Filter attributes scale the size of the filter and let you specify the amount of blur in the texture map. Use it as an anti-aliasing technique used to refine file textures, reduce flickering, or to achieve special effects.

By default, Filter is set to a value of 1.0 to help prevent such aliasing effects. The effect of Filter is related directly to eye space. As the object moves further away from the eye, the more the texture blurs.

For more information, see Texture filtering.

Filter Offset

Controls the texture blur in texture space (not eye space). Use Filter Offset for a blurred effect instead of anti-aliasing. Maya adds a constant value to the Filter setting. The default value is 0. Increasing the value increases the texture blur. For example, 1.00 completely blurs the texture.

Tip

A Filter and Filter Offset of 0.00 results in no blur effect, but a small amount of blur can help reduce moiré and aliasing effects in texture maps.

Invert

Reverses all texture colors (black becomes white, white becomes black, and so on). Invert is off by default. For example, you can change a bump or displacement map’s raised regions to depressions and vice versa by setting Invert on or off.

Local, Wrap

Wrap repeats or tiles the texture completely over the object. If off, everything outside the 3D placement cube displays the texture’s default color. Wrap is on by default.

Tip

Some nodes, such as the Reverse utility, repeat themselves to achieve the effect of Wrap, so that it extends infinitely. Others, such as a Marble texture, extend outwards without repeating.

To adjust texture placement on all objects at once, turn Local on, transform the texture placement icon, then turn Local off to see the results. Turning on Local also means that if you transform any of the objects during an animation, the 3D texture transforms accordingly.

Blend

Controls how much of the texture’s Default Color is mixed into the texture Color. A value of 0 means the Default Color does not affect the texture Color. As you increase the Blend value, more and more of the Default Color mixes in. This attribute does not work unless Wrap is turned off and Local is turned on.

To blend colors and textures using the Blend slider

1. Change the Default Color (in the Color Balance section of the texture’s Attribute Editor), or map another texture to the Default Color.
2. Make sure Invert and Wrap are off and turn Local on.
3. Drag the slider to change the Blend value.

   Color Remap

   Applies a color map to the texture and lets you add or subtract colors from a texture’s default settings. Maya maps the U value to the original texture’s hue, and the V value to the original texture’s intensity. (Color Remap is similar to the Shading Map material and uses the Rgb to Hsv Color Utility.)

To remap a texture

1. Click the Insert button under the Color Remap section. The texture colors change and a Remap Ramp Attribute Editor appears. Adjust the Ramp texture colors and attributes if necessary.
