You can render all layers to Adobe Photoshop (PSD) format.
A PSD file is created during a render with each layer in your scene as a separate layer in this PSD file and with all blending modes specified as they were specified in the Maya file. When you open this file in Adobe Photoshop, each render layer in your Maya scene will have a corresponding layer and blend mode in the PSD.
The PSD file is rendered directly to the image directory of your project and not in a subdirectory.
