Blending Impasto with Other Layers

You can control how Corel Painter blends Impasto brush strokes with imagery on other layers by selecting a composite depth method on the Layers palette.

The Composite Depth menu provides the following methods for combining Impasto brush strokes:

• Add - When this method is active, Corel Painter combines depth information between layers-brush strokes on different layers build up where they overlap.

Painting with an Impasto variant on a layer with Add set does not change the composite depth setting.

Painting with an Impasto variant on a layer with Ignore set changes the method back to Add.

An example of the Add Composite Method.

• Subtract - When this method is active, depth information between layers is removed. Impasto brush strokes on top layers create grooves in the image data beneath them.

Painting with an Impasto variant on a layer with Subtract set does not change the composite depth setting.

• Replace - When this method is active, layer masks replace the depth information from lower layers with information from top layers. Wherever strokes overlap, only the top stokes are visible; the lower strokes are completely covered.

Painting with an Impasto variant on a layer with Replace set does not change the composite depth setting.

An example of the Replace Composite Method.

• Ignore - When this method is active, Impasto brush strokes do not interact with image data on different layers.

With Ignore active, the display of depth for the layer is turned off, even when the View Depth icon on the document window is active. This makes it possible to disable display of depth for individual layers.

Painting with an Impasto variant on a layer with Ignore set changes the method to Add.

This is the default composite method.

You can set a different composite method for every layer in a document. Refer to "Blending Layers Using Composite Methods" for more information.
