Watercolor brushes can be used only on Watercolor layers; on a Watercolor layer,
you can paint only with Watercolor brushes.

You can’t paint across grouped layers — you must collapse the group first. For
more information, see “To collapse a group” on page 62.
Before painting on a shape, you must commit it to a pixel-based layer.
Corel Painter prompts you to commit a shape if you attempt to paint on it. Once
committed, you cannot re-access the shape’s vector controls. For more information,
see “To paint a shape” on page 350.
You can protect areas of a layer from painting by creating a selection. For more
information, see “Creating Selections” in the Help.
You can control what parts of a layer are visible and hidden by creating a layer
mask. For more information, refer to “Working with Layer Masks” in the Help.
To paint on a layer
1 On the Layers palette, select a layer.
2 On the Brush Selector bar, choose a brush category and variant.
3 Paint on the layer in the document window.
The Preserve Transparency option on the Layers palette affects what areas of a layer
you can paint on. Refer to “Preserving Layer Transparency” on page 65 for more
information.
Brush Methods and Painting on Layers
The Natural-Media environment allows brush strokes on different layers to interact
with each other. However, mixing brush strokes that use the Cover and Buildup
methods on the same layer can produce unexpected results. This is caused by a conflict
between the brush method and the layer’s composite method.
Brushes that use the Buildup method — such as those in the Felt Pens or Pencils
category — work best on layers that use the Gel composite method. In fact, when
you use the Buildup method to paint on a blank layer, Corel Painter automatically
sets the layer’s composite method to Gel.
Brushes that use the Cover method work best on layers that are set to the Default
composite method.
