Optimizing V-Ray for Unreal Engine

First posted on Unreal Engines blog on February 15, 2019. V-Ray is one of the worlds biggest physically-based renderers which is used in a variety of markets from architectural firms to visual effects. The Chaos Group (which owns and develops the V-ray software) noticed Unreal Engines rapid growth within similar markets, but with the agenda of interactive or immersive experiences.

The two soon realised that no matter whether its architectural visualisation, automotive, or visual effects all had a common need. A need for smooth workflows and reliable results across all toolsets. Which they now provide through their ‘V-Ray for Unreal Engine’ paid plugin.

‘V-Ray for Unreal Engine’ enables artists to easily import and repurpose V-Ray scenes created in 3Ds Max, Maya, Rhino, or SketchUp. Without the need to learn new rendering paradigms, its all done through the engine.

Lights and materials are automatically imported and converted into their real-time equivalents in Unreal. The software also introduces V-Ray Light Baking, enabling artists to bake V-Ray lights directly into Unreal with full GPU acceleration for the highest-quality real-time illumination.

The ‘V-Ray for Unreal Engine’ is the best solution if you want to import V-Ray scenes from Maya, SketchUp, and Rhino. Datasmith can also be integrated with it’s import / export features and provide data optimisation tools to increase workflows.

Some early tests have given slow results as these new methods will push your systems to the max, so it’s important to consider the optimisation options and such things as LOD and lighting, there’s a good article / document on cinematic optimisation here. At Siggraph in 2018 Unreal presented “A life a bokeh” that showed developers how to optimise assets for real-time rendering, we’ve provided a PDF to the original presentation file here.

The PDF gives you some great insights as to things to consider when building assets and importing them for realtime rendering, it will also introduce to to what game developers call the ‘cost’. This is the cost that functions and assets have in terms of memory and process times. Understanding the cost of your developments will help you to optimise your imports from V-ray into unreal engine. ‘V-Ray for Unreal’ is available now. For pricing and availability, or to download a trial version, visit the Chaos Group website.

Good luck, now make it shine.
