Overview
...
The VRayTranslator node is an advanced Exporter for single frame or animated .vrscene files. V-Ray Standalone integration enables rendering the scene in V-Ray Standalone within NUKE Nuke using Progressive rendering, RT, and Distributed rendering.
...
rtSampleLevel – Specifies the maximum number of paths per pixel for a frame when using the RT engine. The default is 0, which indicates no limit.
...
Note: The default system temp folder, usually C:\Users\<username>\AppData\Local\Temp on Windows (%TEMP%) or /tmp on Linux ($TMPDIR), is used for copying the assets if the VRAY_ASSETS_CACHE_PATH environment variable is not set.
cachedAssetsLimitType – Puts a limitation on the size and age of transferred assets.
...
<value> - Format depends on the type of the parameter you want to
override. Supported types are bool, int, float, color, acolor, texture
and float texture.
For bool, int, and float, a simple number is expected.
For color - Color(1, 0.0, 1.0) is expected. For acolor - AColor(1.0, 0, 0, 0.3).
For texture, the format should be the same as for acolor a color or the name of a plugin to connect to the parameter.
...
configFile – The path and file name for the V-Ray config file, which contains paths to the V-Ray plugins. Note that additional paths for V-Ray plugins can also be specified with the VRAY_PLUGINS_x86 and VRAY_PLUGINS_x64 environment variables. The default is vrayconfig.xml in the same folder as vray.exe .
...
command Line – The parameters in this tab automatically create the options in the command line. These can be manually entered by unlocking the command line with the Lock/Unlock parameter. See the V-Ray Standalone Command Line Options page for variables..
Lock/Unlock – Enables locking and unlocking of the Command Line parameter.
...
No compression – Disables all compression.
Run-length – Basic form of compression comparable to the one used by Targa/BMP files.
Scanline Zip – Zip style compression applied to individual scanlines.
Block Zip – Zip style compression applied to blocks of 16 scanlines at a time. More effective than Scanline Zip but can be slower to decompress.
PIZ – Uses a new combined wavelet / Huffman compression. This form of compression is quite effective when dealing with grainy images, and will often surpass any of the other options under grainy conditions.
PXR24 – Converts data to 24-bit then uses Zip compression. It is lossless for half and 32bit 32-bit integer data and slightly lossy for 32bit 32-bit float data.
B44 – This form of compression is lossy for half data, and stores 32-bit data uncompressed.
B44A – An extension to B44 where areas of flat color are further compressed. Regular B44 compresses uniformly regardless of image content.
DWAA – JPEG-like lossy compression format. Compresses 32 scanlines scan lines together.
DWAB – Same as DWAA, but compresses blocks of 256 scanlines to achieve a better compression ratio.
...
Auto data window (multi-channel scanline file only) – When enabled, V-Ray will automatically try to find the valid data window for the image based on the alpha channel. This option works only for multi-channel OpenEXR files , when the Memory frame buffer option of V-Ray is set to Full.
...
GPU texture format – Controls the file format of the material textures used in GPU rendering. Choose between 8-bit, 16-bit and 32-bit. This does not affect textures used for lights and displacement.
GPU Resize textures – When enabled, resizes high-resolution textures to a smaller resolution to optimize memory usage. This parameter is only effective when the rtEngine option uses Open CL or CUDA.
