Interactive Photorealistic Render (IPR)
AMD Radeon ProRender supports Maya IPR rendering allowing you to visualize your entire scene or a part of it. As you make changes to the scene, for example, tune the lighting, materials or textures, the IPR image is updated, so that you can see the results of your changes interactively.
For detailed information about this render method and how to work with it, see About Interactive Photorealistic Rendering (IPR) in the Maya documentation.
