This page introduces you to the VRayMtl, which is the major building block for most shading networks in V-Ray.

 


Overview

The VRayMtl is a very versatile material that allows for better physically correct illumination (energy distribution) in the scene, faster rendering, and more convenient reflection and refraction parameters. This material can be easily set up to simulate a huge variety of surfaces from plastics to metals to glass and more by adjusting a handful of parameters.

Furthermore, with the VRayMtl you can apply different texture maps, control the reflections and refractions, add bump and displacement maps, force direct GI calculations, and choose the BRDF for how light interacts with the surface material. 


Read more about the Basic Parameters that control properties like the diffuse and opacity colors, or the articles on Reflection, Coat Layer, Refraction, Sheen Layer, Bump and Normal Mapping and the Options of VRayMtl.

Presets – Available in the Maya Node Preset menu, the VRayMtl presets offer values for commonly used materials. See the VRayMtl Presets example below for more information.

Presets use settings that work well (in terms of speed and realism) as a starting point or for general-use cases. However, when a custom scene requires it, the material parameters values can be further edited to work best. For example, Glass and Glass (Tinted) use glossiness values that speed up rendering, but rendering a close-up view of a realistic glass object may require further adjustments. For an in-depth approach refer to the How-To tutorials.

Non-realistic material presets, such as Chocolate, Plastic, Ceramic, and Rubber are ‘quick’ compared to their realistic (SSS-enabled) counterparts. They can be used for generic plastic for the plastic backs of computer monitors or laptops in a meeting room, or for the car tires in a scene where the cars are somewhere in the distance, etc.
