476 Corel Painter X3 Getting Started Guide
The Composite Depth menu provides the following methods for combining Impasto
brushstrokes:
•The Add method, which is the default Composite Depth method, combines
depth information between layers. Brushstrokes on different layers build up where
they overlap. If the composite depth method is set to Add and you paint with an
Impasto brush variant on a layer, the composite depth setting does not change.
An example of the Add composite depth method.
•The Subtract method removes depth information between layers. Impasto
brushstrokes on top layers create grooves in the image data beneath them. If the
composite depth method is set to Subtract and you paint with an Impasto brush
variant on a layer, the composite depth method does not change.

•The Replace method uses layer masks to replace the depth information from lower
layers with information from top layers. Wherever brushstrokes overlap, only the
top brushstrokes are visible; the lower brushstrokes are completely covered. If the
composite depth method is set to Replace and you paint with an Impasto brush
variant on a layer, the composite depth method does not change.
