Physically Based

Iray is a high-performance, global illumination rendering technology that generates imagery by simulating the physical behavior of light interaction with surfaces and volumes. Images are progressively refined to provide full global illumination—including caustics, sun studies, and luminance distribution



All lights work automatically with our physically-based materials to provide a real world effect

Producing visualisation that is truly photorealistic is a continuous challenge; Iray+ allows the user to choose from a range of lighting options to simulate material behaviour to achieve this.

Iray+ provides a catalogue of real world materials for use in photorealistic renders

Iray's MDL (materials definition language) defines the material properties and parameters for all components; surface colour, reflections and refractions, light emissions, surface scatter, displacements and bumpmaps are all easily interchangeable.
