help NVIDIA Iray FAQ

Is NVIDIA Iray still being actively developed by NVIDIA?

While widely used in professional workflows, NVIDIA officially paused active feature development for the standalone Iray Server and SDK products in the early 2020s. The company has shifted its focus toward the NVIDIA Omniverse platform and MDL ecosystem.

Which design software integrates NVIDIA Iray for rendering?

NVIDIA Iray is heavily integrated into Dassault Systèmes' 3DEXPERIENCE platform, specifically within Solidworks Visualize. It allows industrial designers to generate photorealistic images of their CAD models using physically based materials.

Does NVIDIA Iray support rendering on multiple GPUs?

Yes, Iray is specifically engineered to leverage NVIDIA CUDA technology for massive GPU acceleration. It scales efficiently across multiple GPUs, allowing designers to achieve near-real-time lighting previews by distributing the ray tracing workload.

Does Iray use unbiased path tracing for light simulation?

Yes, the engine utilizes physically based, unbiased path tracing to accurately calculate how light interacts with surfaces and materials. This results in mathematically correct global illumination and highly photorealistic final renders.
