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.
The following table describes how Corel Painter layer composite methods are converted to blend modes in Photoshop:
For more information, see Blending layers by using composite methods.
If you save a file to a file format other than RIFF or PSD, the layers drop (or merge) into a single background image.
