V-Ray 7 for Houdini, update 4 is here.

Learn what's new in the latest release.

This update lets you seamlessly match real-world scans to your 3D scenes with Gaussian Splat relighting, and speed up production with faster, more memory-efficient rendering. Designed to deliver pixel-perfect final frames with maximum efficiency, regardless of your pipeline or hardware configuration, the release also adds intuitive, artist-friendly workflows and tools that put complex looks and stunning effects within effortless reach, including enhancements to V-Ray’s Volume Shader, more control in compositing, and more.

Create worlds. Light them perfectly.

Pre-production
Match real-world environment scans to your 3D scene’s lighting.

Gaussian Splats relighting

Blend Gaussian Splats beautifully and naturally into any environment with seamless real-world scan integration via splat asset relighting. Easily match a Gaussian Splat’s lighting to your scene, making it effortless to blend captured locations, especially those scanned under ambient lighting, directly into your 3D worlds. From early-stage previz to final production, you can freely adjust your scene lights at any time without wasting hours working around baked lighting.

Faster rendering on any setup, for any look.

Production
Deliver pixel-perfect shots with maximum efficiency, regardless of your pipeline or hardware configuration. Bring your ideas to life with tools that make complex looks and stunning effects effortless to achieve.
Even faster time to first pixel

Experience highly responsive rendering with a significantly faster time to first pixel. V-Ray GPU IPR now starts up to 2x quicker, thanks to accelerated asset uploads to VRAM and faster texture compression.

Profile-Guided Optimizations (PGO)

Get up to a 13% performance gain in CPU rendering, thanks to our switch to the Intel® ICX Compiler and the implementation of Hardware Profile-Guided Optimizations supported by Intel® Core™ Ultra processors. Speed up your workflow and experience best-in-class performance to maintain your creative momentum and meet even the tightest production deadlines.

Light Cache Denoising

Get cleaner, smoother rendering previews faster and enjoy a significantly improved interactive rendering experience, no longer having to look at a noisy image for long. By applying the denoiser directly to the Light Cache before the actual rendering begins, high-frequency noise is smoothed out instantly. This feature is enabled by default for the NVIDIA Denoiser, delivering better interactive feedback with zero extra setup required for users on the latest version of V-Ray.

Out-of-frustum displacement tessellation

Optimize your scene memory when rendering complex displacement and subdivision surfaces. Control and dynamically dial down the tessellation detail of geometry that falls outside the camera's view frustum, or in other words objects not visible to the camera, significantly reducing memory usage, accelerating geometry compilation, and achieving faster render times without compromising visual quality.

Distributed Rendering 2 (DR2)

Experience a next-generation, distributed rendering system designed to deliver a consistent, high-performance rendering experience for both progressive and bucket rendering across all V-Ray integrations in your pipeline. DR2 eliminates machine limits entirely, allowing your rendering power to scale infinitely as the more machines you add, the faster your renders become. Gain more control and optimize network performance with DR2’s dedicated dispatcher machine to coordinate workloads, plus intelligent bucket splitting and asset caching to completely eliminate bottleneck delays on large, complex scenes.

Effortless artistic control

V-Ray Parallax Texture

Breathe life into massive cityscapes and background buildings while saving time on modeling and keeping your scenes light and fast to render. The V-Ray Parallax Texture lets you create the perfect illusion of fully furnished, beautifully lit rooms behind your windows using just textures instead of heavy 3D geometry. As your camera moves through the scene, the interiors shift dynamically to preserve a convincing sense of depth from every angle, letting you effortlessly dress vast environments so you can focus on the bigger creative picture.

Quick caustics

Enable the new, quick caustics in V-Ray to easily generate stunning light refraction patterns, bypassing the tedious, trial-and-error setup of the traditional photon-based workflow. Much simpler to control and significantly faster to render, a single depth toggle delivers believable underwater caustics without the high performance cost of full photon tracing. The result is realistic caustics with minimal effort, making complex light simulation accessible, predictable, and highly practical for every artist and project.

New Volume Shader enhancements

Optimize and speed up V-Ray volume rendering further with powerful, new parameters. Gain control over velocity motion blur, dynamically scale the motion blur effect and sampling rate to balance quality and performance, making it faster to render complex effects, all while enjoying an updated user interface that delivers a more intuitive experience and a streamlined workflow.

Flexible, seamlessly integrated rendering

Support for the latest host app version

Whenever you’re ready to update your host platform to benefit from the latest features, you can do so with the confidence that you’ll maintain rock-solid rendering stability. V-Ray now officially supports Houdini 21, and update 4 also adds initial support for the newest Houdini 22.

Hydra 2 support

V-Ray for Houdini now officially supports the latest Hydra 2 scene processing framework, ensuring flawless communication with Houdini’s Solaris environment. This latest architecture delivers highly optimized scene processing for complex USD scenes.

More control in compositing.

Post-production
Easily integrate CG elements with live-action footage, work with volumes effortlessly in post.
Backplate workflow

Your live-action compositing workflow just got easier. You can now easily integrate CG elements with live footage using advanced Light Path Expression (LPE), which allows you to isolate reflections and Global Illumination (GI) from holdouts. This workflow gives you the tools and control to perfectly blend digital assets into real-world plates, eliminating the need for manual tracking and complex masking in post.

LPEs for Volumes

Working with volumes in compositing just got a lot easier thanks to Light Path Expressions (LPEs) for Volumes. Now you can easily isolate the light cast by smoke, clouds, or fog in your scene, or extract the self-illumination of a fire into a separate render channel, simplifying post-production for scenes with effects.
