Chaos V-Ray for Houdini
Super-fast production rendering for VFX artists
The ultimate 3D rendering software for procedural effects
V-Ray® for Houdini is a production-proven CPU & GPU rendering software for high-end VFX and animation. It comes with all the tools artists need to render amazing-looking procedural effects. Seamlessly integrated in Houdini, it enables smooth scene exchange and iterations between Houdini and other DCC applications.
Emmy and Academy Award-winning ray tracing technology
V-Ray’s performance is production-proven. It’s been used by the world’s leading studios to render over 300 television series and feature films. In 2017, V-Ray received a Sci-Tech Academy Award for its contribution to photorealistic visual effects. In 2021, V-Ray was awarded with an Engineering Emmy for advancing the use of fully ray-traced rendering.
Fast and scalable to help you meet tight deadlines
V-Ray’s adaptive ray tracing is highly optimized for superior speed and scalability. You can take full advantage of your hardware rendering on multiple CPUs, & GPUs, or both. With V-Ray’s distributed rendering, you can render a single image across multiple machines.
Smart integration for a smooth workflow
V-Ray works seamlessly with Houdini and enables smooth scene exchange with other DCC applications. ACEScg support is new in V-Ray 5, joining other industry standards like Alembic, OpenVDB, and OpenColorIO.
Creative control to render anything imaginable
Bring your projects to life with the right tools for the job. V-Ray equips you with a complete set of lighting, shading, and rendering tools. It’s the most full-featured 3D rendering software available.
Take advantage of your favourite renderer right in Houdini, with all the features you are used to plus a number of important updates. V-Ray 5, update 2 includes a fully-featured V-Ray Hydra delegate for Solaris and support for Houdini 19. You can take advantage of the new V-Ray Decal to easily add stickers, labels, cracks, stains, scratches, and more to your projects. Plus, the latest hair improvements let you render blond, gray, white, and other bright hair colors more accurately.
Simplified workflow and ultimate creative control
V-Ray for Solaris
V-Ray 5, Update 1 introduced the V-Ray Hydra delegate to Houdini. In this update, we’ve added support for AOVs, volumetric effects, and batch rendering with the Hydra delegate through Husk. We’ve also implemented many features and speed improvements.
Houdini 19 support
Houdini 19 introduces many workflow improvements for layout and rendering that are now fully supported by V-Ray.
Apply decals to any surface without altering the underlying material or adding UVs. The new V-Ray Decal makes it easy to add stickers, labels, cracks, stains, scratches, and more.
Enhanced V-Ray Curvature Texture
The latest update to the V-Ray Curvature Texture adds individual controls for convex and concave areas. A new option to ignore bump maps makes the curvature masks even more accurate.
Atmospheric light contribution control
Easily adjust how much an individual light illuminates the environment fog around it with newly added lighting controls.
Render blond, gray, white, and other bright hair colors more accurately with the updated V-Ray Next Hair Material.
Boosted performance in just a few steps
Enhanced ACEScg support
A simpler OCIO setup is now available in the updated UI. We’ve also added the “Auto” option for the color space transfer function, reducing the effort required when building shading networks.
VDB to AUR converter
Chaos Phoenix’s Aura files are rendered faster with V-Ray. A new node makes it easy to perform a quick conversion from VDB to Aura right in the Houdini GUI.
Alembic workflow updates
The newly added PatternID texture simplifies material assignment when working with Alembic files. Plus, we’ve sped up the export of scenes containing large numbers of Alembic files, and the rendering of Alembic files with NUMA machines.
Use the MakeTX tool to easily convert textures to “.tx” files, loaded one tile at a time at render-time. This means quicker loading of textures, less memory consumption, and faster rendering.
Multiple cameras export
You no longer need to export separate .vrscene files for every camera angle. It is now possible to store multiple cameras in a single .vrscene file, so you can save time on your heaviest scenes.
V-Ray Scene Material import and unpacking updates
Unpacking .vrscenes is much faster. We’ve updated the amount of supported shading nodes for material import through .vrscenes coming from other DCCs like Autodesk Maya, and 3ds Max.
High-performance ray tracing
Powerful CPU and GPU-accelerated rendering built for the demands of high-end production.
Fast and accurate rendering of native Houdini volumes and OpenVDB caches.

Isolate selected textures and materials to help debug large shading networks in IPR.
Chaos Cloud rendering
Simple, one-click solution to submit jobs to render on the Chaos Cloud.
Simulate how light interacts with reflective and refractive surfaces, and add a new level of realism to your renders with Progressive Caustics. It’s easy to set up and no longer requires a prepass.
Simplified ACEScg workflow
Enable ACEScg so V-Ray 5 can automatically convert the colors of textures, light temperatures, etc. to the correct color space, without the need of additional nodes.
Unique method for ultrafast rendering of scenes with hundreds or even thousands of lights.
Highly optimized indirect lighting with V-Ray’s proprietary Light Cache and brute force GI methods.

New Sun and Sky Model
A new Sun & Sky analytical model is more accurate and improves lighting at sunrise and sunset.
Blue-noise shows less noise but with the same amount of samples. As your render resolves, depth of field and motion blur will appear smoother with less samples.
