NVIDIA® Iray® is an intuitive physically based rendering technology that generates photorealistic imagery for interactive and batch rendering workflows. Leveraging AI denoising, CUDA®, NVIDIA OptiX™, and Material Definition Language (MDL), Iray delivers world-class performance and impeccable visuals—in record time—when paired with the newest NVIDIA RTX™-based hardware.
The latest version of Iray adds support for RTX, which includes dedicated ray-tracing-acceleration hardware support (RT Cores) and an advanced acceleration structure to enable real-time ray tracing in your graphics applications.
In the 2019 release of the Iray SDK, all render modes utilize NVIDIA RTX technology. In combination with AI denoising, this enables you to create photorealistic rendering in seconds instead of minutes.
Using Tensor Cores on the newest NVIDIA hardware brings the power of deep learning to both final-frame and interactive photorealistic renderings. This unique capability speeds the completion of final images and smooths interactive rendering for a more rapid understanding of your scene’s composition and lighting.
NVIDIA Material Definition Language (MDL) defines the properties of materials, ranging from the color of surfaces to their reflection or refraction properties to the light emission of surfaces. They even include additional surface geometric properties that are not commonly modeled in the primary geometric description of surfaces, such as cut-outs, displacements, or bump maps.
Iray supports any number or combination of GPUs and CPUs running within the same machine and gives you control over which ones are being used for rendering. This makes multi-GPU systems the preferred choice for Iray applications, even on cloud-based systems.
NVIDIA is continually evolving the Iray feature set to improve the physically based 3D and VR rendering workflows of designers and digital artists.

Daz Studio is a free application that enables creators and artists to visualize their imagination. Targeting scene assembly, artistic composition, and rendering, Daz Studio allows artists to import or load assets from a massive user-generated content library and quickly build a scene leveraging physically based lighting and materials through NVIDIA’s Iray and MDL library. The latest Daz Studio release features RTX-accelerated ray tracing on NVIDIA Turing™-based RTX GPUs, providing creators with a fully ray-traced interactive viewport that resolves in near real time.
Lumiscaphe specializes in innovative digital aspect mockup (DAM) and photorealistic visualization. Patchwork 3D, its real-time 3D rendering software suite, enables the creation of advanced DAMs with complex illumination and animation. Patchwork 3D Engineering now natively uses the NVIDIA Iray rendering engine to support the most demanding engineering and design workflows.
