Chaos V-Ray

Now better than ever.

With V-Ray 5 for Unreal, it’s never been faster or easier to take your V-Ray scenes into Unreal’s real-time engine. Chaos’ smart technology gives you our most flexible and efficient light baking workflow to date, while effortlessly handling the material conversion.

V-Ray for Unreal is a plug-in for Unreal Engine (UE) Editor that allows you to import your V-Ray scenes from 3ds Max, Maya, and SketchUp directly to Unreal Engine Editor for rendering. To point out, V-Ray for Unreal maintains data consistency. In other words, your original materials from V-Ray for 3ds Max, Maya, and SketchUp remain connected to their real-time versions. To explain, call them up when you’re ready to render. Use V-Ray for Unreal for light baking. In addition, use it for the rendering of native UE scenes or of 3rd party data that has been imported to Unreal Engine Editor with Epic’s own Datasmith.

New features in V-Ray 5 for Unreal

Custom light baking controls

V-Ray 5 gives you a new level of control over light baking. Now, in addition to Preview, Medium, and High-quality presets, you can completely customize your render settings. This means you can fine-tune global illumination, sampling, and noise levels so they’re optimized for your specific project.

Post-processing is built in.

V-Ray 5 introduces a new Frame Buffer with post-processing controls built-in. You can make color corrections, combine render elements, and add finishing touches without the use of a third-party image editor. This saves you time and helps you get the perfect look straight from your renderer.

Coat layer

A new Coat layer has been added to the V-Ray Material. In summary, it makes it easy for you to create materials with reflective coatings like coated metal and lacquered wood.

Respect pivot points

Now when you import objects with V-Ray for Unreal, their pivot points will remain unchanged. In previous versions, pivot points were placed at the world origin.

Selective export to V-Ray scene

Select any objects in your scene and export them as a V-Ray scene. This makes it easy to transfer assets to other V-Ray applications.

Intel Open Image Denoise

For users without an NVIDIA graphics card, the Intel Open Image Denoise uses your CPU to reduce noise during interactive rendering.

Blue noise sampling

With blue noise sampling, your rendered image will appear cleaner using the same amount of samples. This is especially noticeable when rendering motion blur and depth of field effects.

Initial out-of-core support

V-Ray 5 adds initial support for rendering large scenes that exceed your GPU memory.

Key Differentiators in V-Ray for Unreal

Automatic migration of V-Ray scenes and assets from V-Ray for 3ds Max, Maya, and SketchUp to Unreal Engine Editor for existing V-Ray users within the archviz and automotive design communities.

Easy scene setup within UE Editor for existing V-Ray users within the archviz and automotive communities – leverages existing V-Ray knowledge for real-time and VR presentations.

Superior visual quality for non-V-Ray users and CAD community via Datasmith data transformation in combination with a state-of-the-art, physically-based raytracing engine.


Import V-Ray® scenes, bake lighting and render from Unreal.

Explore your V-Ray scenes in real-time. Render high-quality lightmaps for light baking. And render photorealistic, ray-traced images and animation. All with V-Ray for Unreal.

V-Ray for Unreal

True Photorealistic Rendering Directly from Unreal

When you render with V-Ray for Unreal, you get the exact same photorealistic quality that V-Ray is known for.

V-Ray taps into the full combined power of your GPUs and CPUs for ultrafast ray tracing.

V-Ray for Unreal

The fast and easy way to bring your V-Ray scenes into Unreal.

If you’re looking for the best way to bring your V-Ray scenes into Epic Games’ popular game engine, then V-Ray for Unreal is for you. Simply create your scene using V-Ray and your favorite 3D application (3ds Max, Maya, SketchUp). When finished, export it. Then import the file into Unreal to explore it in real-time, virtual reality, and more.


Smart translation of materials & lights.

When you import a scene, V-Ray for Unreal automatically converts V-Ray lights and materials to their real-time equivalents in Unreal Engine. You can then edit these in the Unreal Editor using familiar V-Ray controls. What’s more, V-Ray for Unreal keeps track of your original V-Ray materials and uses them whenever you render.

smart transition

Light baking is faster and better with V-Ray.

V-Ray for Unreal can render high-quality lightmaps in a fraction of the time by distributing the rendering across multiple machines. You can render on CPUs and NVIDIA GPUs to take advantage of all your available hardware. You can also use the Chaos Cloud service for easy rendering on-demand. Because light baking is memory-intensive, V-Ray also provides an easy way for you to export your scene and render it anywhere without the overhead of having Unreal open or tying up your machine.

In addition to helpful light baking presets, V-Ray 5 for Unreal now lets you customize your settings for even more control when rendering lightmaps.

smart material translation

Ray-traced V-Ray rendering from Unreal.

Render photorealistic ray-traced images and animation right from Unreal with the well-known V-Ray quality.

In V-Ray 5 for Unreal, you can fine-tune and finish your renders right in the V-Ray Frame Buffer. In other words, composite render layers and make color corrections, all without a trip to a separate app.


With V-Ray for Unreal, you get the best of both worlds — real-time & ray tracing

The fastest, simplest way for you to:

  1. Bring V-Ray scenes into real-time
  2. Render ray-traced images directly from Unreal

Now you can bring V-Ray scenes from 3ds Max, Maya, SketchUp, and Rhino directly into the Unreal Editor. And for the first time, you can render ray traced, photorealistic images with V-Ray directly from Unreal.


Note: Get V-Ray for Unreal as a rental license only (annual and monthly). V-Ray for Unreal supports only the Online Licensing System (OLS) and does not support the USB dongle.
