This page provides information on the Nuke features supported by V-Ray for Nuke.
Overview
As a built-in rendering plugin for The Foundry Nuke, V-Ray supports most of the standard geometry primitives as well as some of the basic shaders inside Nuke. Differences in the operation of the standard Nuke nodes and their V-Ray equivalents are possible.
Note that the list below is not exhaustive.
Geometry Types
The following geometry types are supported:
Polygonal surfaces; optionally, these can be rendered as subdivision surfaces;
Alembic
FBX
V-Ray proxy (supports Alembic and VRmesh file types)
All geometry types support motion blur.
Shaders
The following Nuke shader types are supported:
Diffuse
Emission
Phong shader is partially supported
Specular shader is partially supported
Project 3D (supports "both" and "front" projection modes and self occlusion mode)
UVTile
Displacement is partially supported
Nodes
The following Nuke nodes are supported:
Read
Write
Reformat
Constant
Checkerboard
ColorBars
ColorWheel
Noise
Ramp
Radial
Rectangle
Sparkles
Flare
Bitmap Formats
The following bitmap file types are supported:
JPG
PNG
TGA
BMP
HDR
EXR (regular and tiled mip-mapped)
SGI
PIC
TIFF
PSD
Tiled mip-mapped TIFF files (.tx or .tex)
DDS
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 controlled through the Dynamic memory limit parameter in the Global 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:
Light
Point
Direct
Spot light is partially supported.
Environment Variables
V-Ray Renderer writes output to a log file. In order to use it you need to set up the following environment variables:
VRAY_FOR_NUKE_LOG_FILE_PATH = <temp dir>
VRAY_FOR_NUKE_LOG_FILE_NAME = vray4nuke_log.txt
If you would like to check where your log is written you can check your console window and search for "Created log file: <filepath>"
