The current version of RAYZ imports and exports the file formats in the list below. However, you can add support for other image formats by writing a RAYZ plug-in.
This section provides important information which should be reviewed before importing and exporting the following image file formats.
Refer to the sections of the Image In node description on Conversion Parameters in chapter 14 and Format-Specific Import Options in chapter 14 for specific information about using the parameters relevant to importing and converting image file formats.
For more information about specifying format options when writing image files, refer to the Format in chapter 14, Conversion in chapter 14, and Format Specific in chapter 14 parameter descriptions in the Image Out node.
RAYZ can read and write Kodak Cineon 10-bit log imagery in Fido format. This 3-channel format is by far the most common type of Cineon file.
By default, the Image In node automatically remaps Cineon 10-bit log files to 16-bit linear colorspace. However, you can change the conversion options or use the unconverted log data by setting the appropriate parameters in the Image In Node Panel.
By default, unconverted log images are displayed in the Image Viewer using Raw Log display conversion, which shifts the values up in the colorspace to make them visible without attempting to remap the nonlinear distribution to linear.
To view log data remapped to linear, choose Cineview emulation instead, or add a custom display LUT. Viewer display options are described in the section on Display Conversion in chapter 6.
RAYZ can also read Kodak Cineon imagery in DPX format, which may be linear or log (or have some other type of non-linear gamma), may contain 1, 3, or 4 channels, and may be encoded as 8-bit, 10-bit, 12-bit, or 16-bit data. RAYZ also recognizes the orientation of the image.
RAYZ can write DPX files of 1, 3, or 4 channels, encoded as 10-bit log or as 8- or 16-bit linear.
FRP (pronounced "ferp") is a Silicon Grail file format optimized for Fast real-time Playback. It is used to create a compact flipbook file for in-house playback and review of a shot or shot element.
When you select FRP from the Format menu in the Image Out node or the corresponding entry in the Render Control view, RAYZ writes the specified image sequence to disk at its native spatial resolution as a single .frp file of 8-bit data. You can then load this file into any RAYZ project file and play it in a Viewer.
An Adobe Photoshop format file may contain multiple image layers. There are two ways to import such a file into RAYZ, depending on whether you need to maintain the separate layers.
When imported into the Image In node, a multi-layer Photoshop file is flattened by default, although you can override this option in the Image In Node Panel if you want to import any single layer of the image. See also Format-Specific Import Options in chapter 14.
Another method is available that imports the Photoshop file into a new RAYZ project file and retains each layer as a separate image. The Import File... in chapter 9 option in the RAYZ File menu automatically imports each layer of the Photoshop file into a separate Image In node, and connects the Image In nodes to a Multi-comp node to recreate the multi-layer Photoshop image.
Either the RGBA channels or the Z channel of a 5-channel Maya file can be imported into a single Image In node, but not all five channels, because the depth data is encoded as float while the color and opacity channels are encoded as 8- or 16-bit.
The Image In node provides a parameter you can use to select which Maya channels to import, so that you can import the RGBA data into one Image In node and the corresponding z-buffer into another. See also Format-Specific Import Options in chapter 14.
RAYZ 2.2 can read QuickTime 3 compliant files that use the Animation, JPEG, Motion-JPEG-A, YUV2, and uncompressed codecs. The file may include audio (although RAYZ 2.2 cannot play the audio track).
Unless you change the default, YUV files will be imported as floating point to ensure that all the image data is preserved. In addition, RAYZ assumes that imported YUV files have a gamma of 2.2. You can change the default bit depth and gamma specification for YUV files in the Image In node. See also Format-Specific Import Options in chapter 14.
Like some Maya image files, Alias/Wavefront RLA and RLB file formats may contain channels of data other than the RGBA channels. These channels can be imported into a separate node from the RGBA data by using the appropriate parameter in each Image In node to select which channels to import. See also Format-Specific Import Options in chapter 14.
