V-Ray

Overview

V-Ray is a rendering engine that uses advanced techniques, for example global illumination algorithms such as path tracing, photon mapping, irradiance maps and directly computed global illumination. The use of these techniques often makes it preferable to conventional renderers which are provided standard with 3d software, and generally renders using these technique can appear more photo-realistic, as actual lighting effects are more realistically emulated.

The desktop 3D applications that are supported by V-Ray are:

Why should you learn

VR Cameras – Two new VR Camera types to render stereo cube maps and spherical stereo images for VR headsets such as Oculus Rift and Samsung Gear VR.

Simplified User Interface – V-Ray 3.0 introduces a simplified User Interface and includes 3 modes: Basic, Advanced, and Expert. Modes can be toggled at any time to reveal additional controls. The default, Basic mode is designed to meet the needs of most artists’ daily production work.

New Skin Shader – A dedicated, intuitive Skin shader with layered specular highlights will make it easier than ever for artists to create complex, layered skin.

Probabilistic Lights – Increases the speed of scenes with a high number of lights. Probabilistic Light Sampling reduces the number of lights evaluated at render time.

Progressive Rendering – The new Progressive Production Renderer is built on the same path tracing technology as V-Ray RT and it is a simple, intuitive solution for any scene. The Progressive Renderer is compatible with all V-Ray production features, including Irradiance, Light Cache, SSS, Render Elements, etc.

Faster Ray Tracing – V-Ray 3.0 introduces a significantly optimized ray tracing core to speed up calculations for Brute Force GI, Progressive Path Tracing, Reflections, Refractions, and more. Depending on scene complexity, users are reporting speed increases up to 5X.

Quick Settings – Quick Settings provide artists with production-ready presets and simple rendering quality controls all within a single compact interface.

Advanced V-Ray Frame Buffer – Consistent color output is essential to artists’ workflows. V-Ray 3.0 has been expanded to utilize a variety of color definitions including LUTs (.cube), ICC Profiles (.icc), and OpenColorIO (.ocio). By default V-Ray 3.0 is set up for linear workflow, making it easier to ensure reliable, accurate colors.

Render Mask – Render Mask uses an object selection, include/ exclude list, or texture map to control the exact pixels to be rendered.

Faster Hair – V-Ray 3.0 introduces faster hair rendering speeds (up to 15x) and view-dependent tessellation that automatically smoothes hair curves.

Ray Traced SSS – Improved Subsurface Scattering is offered, including options for object-based and ray traced illumination.

Max Ray Intensity – Max Ray Intensity clamps secondary rays to remove noise generated by very bright sources. This removes artifacts while retaining dynamic range.

VRmats – VRmats (formerly Vismats) are universal V-Ray Shaders for use across multiple applications. For example a VRmat material may be created in V-Ray for 3ds Max and transferred directly to V-Ray for Maya.

Learning Outcome

You can edit your work in real-time and everything is designed to save you time. This means you can set up a visualization in just a few minutes and make alterations as you go. End results are rendered using GPU rendering technology. This ensures that your movies render in a fraction of the time required by other solutions. With V-Ray you have more than enough time for videos in situations where you would normally have to settle for still images.

Rendering is just one of the things necessary to create effective visualizations. To create wonderful visuals you also need beautiful skies, water, grass, materials, plants, people, trees and many other objects. Usually you will have to hire people to create these extra assets for you or find a third party content library. V-Ray includes a huge library of tools and content. Everything is perfectly integrated so you can immediately add trees, people and other content to breathe life and atmosphere into your visualizations.
