VRay is a rendering software used in 3D computer graphics to create high-quality images and animations. It is a plugin that works with several 3D modelling software such as 3ds Max, Maya, SketchUp, Rhino and others. VRay uses advanced algorithms and techniques to simulate the behaviour of light and its interaction with objects in a virtual 3D space, resulting in photorealistic renderings. It offers a wide range of features such as global illumination, ray tracing, texture mapping and depth-of-field effects, among others. The software has become a popular due to its high level of customisation and flexibility.
