Chaos Group releases Chaos Vantage

Wednesday, December 2nd, 2020 | Posted by Jim Thacker

 
Chaos Group has released Chaos Vantage, its new tool for exploring large V-Ray scenes in real time.

The software, previously known as Project Lavina, makes use of the RT cores in current-generation Nvidia RTX graphics cards to generate an interactive real-time, fully ray traced view of the environment.

It is available free until June 2021, after which subscriptions will cost $389/year.

A new tool for scouting very large architectural scenes in real time
First shown as a tech preview at Siggraph 2018, and released in public beta this summer, Chaos Vantage is pitched as a tool for exploring large 3D scenes in a fully ray traced environment.

Although there are potential uses for visual effects and animation – for example, scouting virtual sets – the main target market is architectural visualisation.

Potential use cases include simply viewing very large architectural scenes like massing models, scouting camera positions for offline renders in V-Ray, and generating real-time previs-quality animations.

 

 
Renders scenes in .vrscene format and live-links to 3ds Max
Chaos Group’s pitch for using Vantage over other real-time rendering solutions – particularly Unreal Engine, which is free for this kind of work – is ease of use.

Rather than having to convert scenes created for offline renders into a form suitable for use in a game engine – still a time-consuming process, despite tools like Datasmith – Vantage can render the original versions.

It imports scenes in .vrscene format, the scene file format supported in the standalone edition of V-Ray and most key editions of the renderer, including V-Ray for 3ds Max, Maya, Modo, Revit, Rhino and SketchUp.

As well as navigating the scene, using game-like controls with automatic collision detection, users can perform simple edits inside Vantage, moving, transforming, duplicating, hiding or deleting objects.

Vantage also live-links to 3ds Max, with changes made to a scene inside Max updating in Vantage in real time, enabling the software to function as a ray traced viewport.

Doesn’t yet support all advanced features of V-Ray scenes
However, that doesn’t mean that imported scenes will necessarily look identical in the two applications, since Vantage doesn’t currently support all of the features of the .vrscene format.

Coverage varies according to host application: in 3ds Max, most light types, V-Ray Sun, the physical camera, and most basic materials and maps are supported.

Features not currently supported include mesh lights and V-Ray Ambient Light; advanced settings for shadows, the Dome light and physical camera; and some key materials like VRayDirt and VRayDistanceTex.

Designed specifically for Nvidia’s RTX hardware
Unlike V-Ray GPU, V-Ray’s own built-in GPU renderer, Chaos Vantage has been designed from the outset for real-time ray tracing – and for Nvidia graphics cards.

The application makes use of the RT hardware cores in Nvidia’s current-gen GeForce RTX, Titan RTX and Quadro RTX GPUs to accelerate ray tracing operations.

Whereas V-Ray GPU, like most conventional DCC tools, uses Nvidia’s OptiX API for RTX acceleration, Vantage takes the same route as Unreal Engine, using Microsoft’s DXR (DirectX Raytracing).

The initial release “averag[es] 24-30fps on a consumer-grade Nvidia RTX card at HD resolution”.

Clearly, that will depend on the scene being viewed, but Chaos Group claims that Vantage can “handle billions of polygons without any loss in detail or significant decrease in speed”.

Built-in animation editor creates simple camera animations
As well as simply exploring scenes, Vantage can be used for rendering in its own right.

The software includes its own animation editor, making it possible to create simple camera animations by setting camera positions and transitions between them.

Chaos Group describes the output as being suitable “for presentations or previsualization purposes”, rather than as an alternative to final-quality rendering in V-Ray.

New since the beta releases: motion blur and two layers of environment fog
If you’ve been following our coverage of the original beta releases of Project Lavina, there are also a few new features in Chaos Vantage.

One of the biggest is support for motion blur and denoising in offline renders: both for still images and animations, which can now be rendered in .mp4 and .mkv format.

Users can also now record the viewport in real time in .mp4 format.

Vantage also supports environment fog – it is now possible to use two fog layers with independent settings – and LUTs, with support for colour space settings for LUT files.

Pricing and system requirements
Chaos Vantage is available for Windows 10 only. To use it, you need a Nvidia RTX GPU and Nvidia driver 436.02 or newer.

The software is rental-only: one-year licences are free until 2 June 2021, after which subscriptions will cost $389/year. Vantage has also been added to Chaos Group’s V-Ray Collection product bundle.
