| The V-Ray.exe project |
Command line parameters
One can override all of the V-Ray executable options
through the command line parameters which are passed when executing V-Ray.exe.
List of V-Ray.exe command line parameters. The order
of the parameters passed is irrelevant. Please note that if you wish to use
blanks in the parameter values, usually in the file names, you have to put double-quotes.
Note the syntax in the examples below.
| Parameter | Meaning | Examples |
| -output | After finishing the rendering process saves the rendered buffer to this file. Currently supported format is PNG. Make sure you use the .PNG extension - otherwise no file will be saved. The directory ,if provided, in the file name must exis -. otherwise the file will not be saved | v-ray.exe -output=firstoutput.png v-ray.exe -output="c:\program files\3dsmax50\images\my file.png" v-ray.exe -output=c:/temp.png |
| -numframes | Sets the numbers of frames to render before exiting. If this parameter is not set - the rendering will continue forever until the dialog box is closed manually by a user. Setting a value of -1 will cause an endless render until a user closes the dialog. | v-ray.exe -numframes=4 v-ray.exe -numframes="3" v-ray.exe -numframes=-1 |
| -useao | Turns on/off the ambient occlusion | v-ray.exe -useao=1 v-ray.exe -useao=0 |
| -incao | Turns on/off the incremental ambient occlusion sampling mode. | v-ray.exe -incao=1 |
| -aosamples | Sets the number of Ambient Occlusion samples to make per render. | v-ray.exe -aosamples=2 v-ray.exe -aosamples="4" |
| -useaa | Turns on/off the anti-aliasing supersampling | v-ray.exe -useaa=1 v-ray.exe -useaa=0 |
| -aasamples | Sets the number of anti-aliasing samples per super-sampled pixel. | v-ray.exe -aasamples=2 v-ray.exe -aasamples="4" |
| -aathresh | Sets the threshold value for the anti-aliasing algorithm. Any difference in the color above this value of neighbouring pixels will force the AA to go into supersampling. | v-ray.exe -aathresh="0.2" v-ray.exe -aathresh=0.03 |
| -vrmeshfile | This vrnesh file will be imported and will be rendered. Multiple parameters vremshfile can be specified. Thus - on can import multiple vrmesh file into one scene and render it all. | v-ray.exe -vrmeshfile="c:\test\mesh_01.vrmesh" -vrmeshfile="c:\test\mesh_02.vrmesh"
v-ray.exe -vrmeshfile=c:\test\kitten.vrmesh |
| -rtshadow | Turns on/off the raytraced shadows | v-ray.exe -rtshadow=0 v-ray.exe -rtshadow="1" |
Examples of how to set up the V-Ray.exe through command line parameters
| The following example imports two v-ray mesh files
ourface.vrmesh and rabbit.vrmesh files, turns on anti-aliasing
and after the user closes the GUI - saves the rendered result to c:\auto.png v-ray.exe -vrmeshfile="C:/projects/vrayexe_tests/ourface.vrmesh" -vrmeshfile="C:/projects/vrayexe_tests/rabbit.vrmesh" -useaa=1 -output="c:/auto.png" -aathresh=0 |
| The following example imports
the mesh file rabbit.vrmesh, turns on ambient occlusion(AO), turns on the
AO incremental sampling and saves the final image after the user closes
the dialog box to c:\rabbitao.png file v-ray.exe -useao=1 -incao=1 -vrmeshfile="C:/projects/vrayexe_tests/rabbit.vrmesh" -output="c:/rabbitao.png" |
| The following example imports
the mesh file rabbit.vrmesh, turns on ambient occlusion, turns on the AO
incremental sampling, sets the number of AO samples to 2 per rendered frame,
renders 20 frames and afterwards closes and saves the final image to c:\rabbit20.png v-ray.exe -useao=1 -incao=1 -aosamples=2 -vrmeshfile="C:/projects/vrayexe_tests/rabbit.vrmesh" -output="c:/rabbitao.png" -numframes=20 |
