Color Composite

Color Composite nodes are commonly used create Opacity masks from multiple textures or to add gradients to textures.

Alpha

This defines the transparency of the composited result. The transparency can be set by either using the slider or applying a texture. The behavior is very similar to the Clipping Mask parameter, but the Clipping Mask has additional controls.

Blend Mode

This defines how the Source and Background layers are blended together.

The following Blend Modes can be chosen: Normal, Multiply, Screen, Overlay, Soft Light, Hard Light, Darken, Lighten, Burn, Difference and Sum. The behavior of these is equivalent to the same blend modes found in most image editing applications.

Source

This is the first and top layer of the texture composite. If the Source texture has alpha (transparency), then this will be propagated to the composite.

Source Alpha

This defines the transparency of the Source layer. The transparency can be set by either using the slider or applying a texture.

Background

This is the second and bottom layer of the texture composite. If the Background texture has alpha (transparency), then this will be propagated to the composite.

Background Alpha

This defines the transparency of the Background layer. The transparency can be set by either using the slider or applying a texture.

Mask Mode

The following Mask Modes can be chosen: Red, Green, Blue, Alpha, Color.
The Red, Green and Blue options refer to the individual RGB channels of the Clipping Mask texture.

Clip Using Source

If the Source texture has alpha (transparency), then this will be used to mask out the composite. The composited result will only show where the Source texture is non-transparent.

Invert Mask

Use this to invert the Clipping Mask texture.

Color Composite Example with Label Opacity

The examples below show how a Color Composite node can be used to create interesting Opacity masks for Label materials.
