General

As a built-in rendering plugin for Autodesk® Maya®, V-Ray supports most of the standard geometry primitives as well as some of the basic shaders inside Maya. Note, however, that in difference from V-Ray for 3ds Max, V-Ray for Maya cannot use the standard Maya shaders, materials, lights etc. Instead, their functionality is emulated by V-Ray specific plugins. Therefore, differences in the operation of the standard Maya plugins and their V-Ray equivalents are possible. In addition, the Hypershade graphs need to be mapped to the V-Ray plugin parameters system.

 

Note that the list below is not exhaustive.

Geometry types

The following geometry types are supported:

All geometry types except Maya Fluids support motion blur.

The Maya conversion utilities can be used to render some of the other Maya geometry types. For example, paint effects can be converted to polygons and then rendered with V-Ray.

Materials

The following material types are supported:

 

For these materials, the supported parameters are:

 

1 - both Layered Shaders and Layered Texture modes are treated as Layered Texture (see the Maya reference for more info on those two modes).

2D and 3D Textures

The following texture types are supported:

 

 

The following texture types are partially supported (they will be mapped to the same V-Ray noise generator):

 

Utilities

The following Maya utilities are supported:

 

 

 

 

 

Bitmap formats

The following bitmap file types are supported:

 

For tiled mip-mapped textures (.exr and .tx/.tex), V-Ray is able to load only parts of the textures as needed during the rendering. By default, tiled textures use the same memory pool as the dynamic geometry used for displacement, proxies etc. The size of this pool can be controled through the Dynamic memory limit parameter in the System tab of the V-Ray render settings. You can also specify a separate memory pool for tiled textures using the VRAY_TEXTURE_CACHE environment variable (see the section on Environment variables).

 

V-Ray also supports a number of tags in the file names, which are expanded at render time. See File names for bitmap textures section for more information.

Lights

The following light types are supported:

VRay Sun & Sky

The VRaySun and VRaySky are special features which are provided by the V-Ray renderer. Developed to work together, the VRaySun and VRaySky reproduce the real-life Sun and Sky environment of the Earth. Both are coded so that they change their appearance depending on the direction of the VRaySun.

The V-Ray Sun and Sky are based largely on the SIGGRAPH'99 paper "A Practical Analytic Model for Daylight" by A. J. Preetham, Peter Shirley, Brian Smits.

 

In the VRaySky tab of V-Ray Render Settings window there are buttons to create the two nodes.

Camera settings

The following Maya camera settings are supported:

 

More V-Ray specific options are available in the Camera tab of V-Ray Render Settings window with separate tabs for DOF and Motion Blur.

 

Environment colors can be overriden and there is an option to easily assign a 2d texture as an environment texture. A V-Ray environment placement node is created with several mapping types available: angular, cubic, spherical, mirror ball.

Animation

The animation settings are in the V-Ray Render Settings window under Image File Output.
Thus a sequence of frames is rendered the same way, only the animation checkbox should be checked and the corresponding start and end frames should be set.
