V-Ray

V-Ray is a render engine developed by Chaos. It is not a modeling program in its own right; it installs as a plugin inside programs such as 3ds Max, SketchUp, Rhino, Revit, Maya and Cinema 4D. Designers can therefore turn a model into a photorealistic image without leaving the environment they work in. Beyond architectural visualization, it is used in film, advertising and product rendering.

Key features

V-Ray can render on the processor (CPU) or the graphics card (GPU), and the better choice depends on the scene and the hardware. It brings physically based materials, light sources, a sun and sky system, camera controls and denoising tools together. Render pass (render elements) support lets reflections, lighting or material layers be saved separately and fine-tuned in post-production. In its own frame buffer, exposure, color and tone can still be adjusted after the render has finished.

Its place in architectural visualization

V-Ray has been used in archviz studios for a long time, so ready-made material libraries, training material and experienced users are plentiful. Its settings are extensive, which gives seasoned users a great deal of control but can lengthen the learning curve for newcomers. Because the same material and lighting logic works across different host programs, sharing files between teams is easier too. We cover how it is used on architectural projects in our article on V-Ray render engine features.
