Iray for 3ds Max Feature List

Rendering

Utilizes the power of NVIDIA's Iray technology on all supported GPUs and CPUs, with user control of hardware resources
Physically based path-trace rendering within 3ds Max's ActiveShade Mode enables accurate preview of final results during scene composition
Super-fast Iray Interactive ray tracing provides immediate feedback on object transforms and lighting edits
AI De-noise filter delivers fast, high quality, noise-free images
AI Upscaling further accelerates rendering performance with almost no loss of quality
Optimized sampling for accurate caustics and highly indirect lighting
Simultaneous Render Element generation with negligible speed impact
Custom Light Path Expressions for tremendous flexibility in post-production editing
Highly responsive Depth of Field and Motion Blur via 3ds Max's camera multi-pass system
Toon Shading post-process support for creating images similar to traditional 2D animated cartoons
Matte shadow and reflection support for compositing flexibility
Backplate image supported independent of lighting
Lighting Analysis feature for simulating and visualising the effects of light and heat on architectural designs
Iray Section Plane slices through entire 3ds Max scene for interior visualization
Lens type for 360 panoramic rendering and stereo viewing with VR hardware

Interactive updates (in ActiveShade) upon adjusting scene materials
Physically based materials using an intuitive layering approach leveraging the NVIDIA Material Definition Language (MDL) for substantial flexibility
Extensive material flexibility, including subsurface scattering, thin film, gemstone, etc.
Work directly within 3ds Max material editing interfaces such as the Compact and Slate Material Editors
MDL material export for building custom, shareable material libraries
MDL import and export for sharing materials between different Iray applications or MDL-compliant renderers (e.g., mental ray®)
