Vray for revit software#
Naturally, this meant working directly inside Revit, but it also meant users would not have to change the material definitions within the Revit model.īy default, when you click render in V-Ray for Revit, the software automatically converts all of the Revit materials into V-Ray materials - a process that takes a matter of seconds. In developing V-Ray for Revit, the primary consideration for the developers was that the rendering process would be non-destructive to the BIM workflow. Other advanced features include environment fog, which can be used to give the effect of light streaming through a window, and aerial perspective, which produces fog in the distance. It provides control over camera settings, such as focus distance, ISO, F number and shutter speed, and is great for producing more stylised output. More advanced users can change depth of field - a feature that is not commonly available in built-in renderers like Autodesk Raytracer. ‘Very high’ uses a bucket renderer, and while this delivers the best results, render times can be significantly longer ( see BOXX review here). By default, draft, low, medium and high use a progressive renderer, which is quicker. While V-Ray RT can be used as a production renderer, for best results with less image noise, Chaos Group recommends using the standard V-Ray engine, which scales well with multi-core CPUs. The speed at which this happens will depend on your hardware, so if this becomes an important part of your workflow then you may need to consider investing in a more powerful GPU, or multiple thereof. This can be great if you want to play with lighting and exposure settings or explore different materials.Īs changes are made, the image will automatically start to re-render in the frame buffer. The key benefit of V-Ray RT is being able to make changes to the scene in real time, without having to re-start the render. This will allow the software to run with pretty much any GPU, including those from AMD. Chaos Group currently supports Nvidia GPUs through CUDA, but will be adding OpenCL support later. While the production engine runs solely on Central Processing Units (CPUs), the calculations for the real time engine can also be done on Graphics Processing Unit (GPUs). V-Ray, the standard production engine, delivers the best quality results, while V-Ray RT, a so-called real time engine, is very useful for tweaking settings before committing to a time- consuming final render.
Rendering engines There are two rendering engines built into the software. These can be applied during or after the render.
The software provides simple slider controls for adjusting exposure, contrast, hue/ saturation and colour balance in real time. Once the render button is hit, the frame buffer appears as a separate rendering windowĮven when the render has started, it is still possible to fine-tune the image. Non-camera orthographic views can be rendered when active. Chaos Group says this issue affects all Revit API applications, including those written by Autodesk, and that it’s currently working with the Revit development team to find a solution. It is not currently possible to render an active camera view, as the plug-in becomes unavailable. To render a scene, simply choose a camera view from a pulldown list. As soon as the render button is hit, the V-Ray frame buffer (rendering window) pops up and the image refines until it is finished. It has its own ribbon in the Revit UI, with simple controls for quality, lighting, exposure and resolution. V-Ray for Revit runs as a plug-in directly inside Revit (versions 2014 to 2017), so no import or export is required. However, unlike many of the renderers that are built into CAD and BIM software, it also gives users access to some of the more advanced controls, albeit in a dumbed-down way. V-Ray for Revit, currently in beta, has been designed from the ground up to be easy to use - push-button simple, if you will. But now its developers are targeting a completely different type of user with a new plug-in for Revit. It’s designed for rendering experts, with hundreds of different settings that can be tweaked to deliver that perfect image. V-Ray is available as a standalone renderer, but is commonly used as a plug-in for Autodesk 3ds Max. The software has featured in virtually all of the rendering and animation projects we have covered in AEC Magazine over the years.
It’s a bold claim, but we’ve no reason to doubt it. The powerful, quick ray trace rendering software is a favourite in the architectural CG community.Ĭhaos Group, its developer, boasts that 92 of the top 100 architecture firms in the world render with V-Ray every day.
To architectural design visualisation specialists, V-Ray needs no introduction. Core materials can be overidden with diagrammatic materials for a quick conceptual render
