You can remove V-Ray from your machine similarly through a silent uninstall. 

UI Text Box

The -auto flag automatically accepts both the End User License Agreement and the Chaos Global Consumer Privacy Policy. It is recommended to get acquainted with them first.



Creating the .xml file

...

Run the installation file from the command prompt with the -gui=0 argument.

vray_adv_60хххxxxxx_max20nnmax20xx_x64.exe   -gui=0

Follow the instructions and set up the installation the way you want to have it on all machines. This creates a file named config.xml in the folder of the installation file. 



Running the installer

...

In the second step, run the installer with the following command:

Code Block
vray_adv_6000470001_max2023max2025_x64.exe -gui=0 -configFile="xml_file.xml" -quiet=1 -auto

 


The -quiet=1 argument causes the installer to read the variable values from the .xml file and does the installation without user input. If you do not specify the -quiet=1 option, the installer asks for a confirmation of each variable before proceeding.

 



Configuration File

...

The config.xml file holds configuration information about the settings of the installation. Below is an example of such a config file.
