Layers 525
When you edit a layer mask, you are making modifications to the mask, not to the
layer’s image. You can use shades of gray only; no colors are available. This is because
the layer mask is a grayscale image that is separate from the RGB image.
The paint and effects you apply to a layer mask are reflected as follows:
• Applying white removes areas from the mask and reveals more of the layer.
• Applying black adds to the mask, which conceals more of the layer.
• Applying an intermediate gray value makes the mask semitransparent.
Importing and exporting layers
You can save your Corel Painter document in the RIFF format with “live” layers — the
layers continue to function when you reopen the file. RIFF is the only format that
preserves layers in their original state.
If you export a Corel Painter document in PSD (Photoshop) format, all layers convert
to standard Photoshop transparent layers. Photoshop does not preserve groups; each
layer in a group becomes its own Photoshop layer. For more information, see “Grouping
layers” on page 502.
