V-Ray for Autodesk® Maya® supports most of the standard geometry primitives as well as some of the basic shaders inside Maya. Note, however, that as opposed to 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 versions. Therefore, differences in the operation of the standard Maya components and their V-Ray equivalents is possible. In addition, the Hypershade graphs need to be mapped to the V-Ray plugin parameters system.
