This page contains information about V-Ray's standalone VRImg to OpenEXR converter.
|Table of Contents|
The VRImg to OpenEXR converter is both a command-line utility and a simple GUI application that can be used to convert .vrimg image files to .exr files in OpenEXR format. The .vrimg file format is a special format used by an application's to store the rendered image incrementally while rendering, in full floating-point format, with all available render elements. The V-Ray Image to EXR Converter converts .vrimg files to EXR format so the render elements may be loaded into compositing software, where they can be used for compositing or fine-tuning at the render element level.
By default, the installation of V-Ray includes the vrimg2exr executible in the bin or tools folder found under [Program Files]\Chaos Group\V-Ray\[host app.]. A shortcut to the converter is also installed in the Start Menu under All Programs > Chaos Group > V-Ray for [Host app.] > Tools > VRImg to OpenEXR converter.
Running vrimg2exr without any parameters, or from the Start menu, will open the GUI version of the tool as seen above. The GUI allows you to convert one or a number of .vrimg files to OpenEXR files. You can also get information about the data stored in a .vrimg file.
Command Line Usage
There are two methods for running the vrimg2exr converter from the command line. In both cases, the original .vrimg file is not deleted.
Converting a single .vrimg file to a single .exr file:
> vrimg2exr <vrimg _file> <exr_file> [options]
In this case, the <vrimg_file> cannot contain wildcards. Note that the .exr extension is not added automatically to the output file name.
Converting multiple .vrimg files to multiple .exr files:
> vrimg2exr <vrimg_wildcard> [options]
In this case, <vrimg_wildcard> can contain the wild-card symbols '*' and '?'; the .vrimg files will automatically be converted to OpenEXR files with the .exr file extension.
One or more of the following options may be specified:
