Setting and getting environment variables within Maya

You can set the value of environment variables within Maya by using the putenv command in the command line.

Examples:

putenv "MAYA_RENDER_SETUP_INCLUDE_ALL_LIGHTS" "0"

putenv "MAYA_CUSTOM_TEMPLATE_PATH" ";C:/Users/myName/Documents/myTemplatePath"

Likewise, you can get the value of an environment variable within Maya by using the getenv command.

Examples:

getenv "MAYA_RENDER_SETUP_INCLUDE_ALL_LIGHTS";
// Result: 0 // 

getenv "MAYA_CUSTOM_TEMPLATE_PATH";
// Result: ;C:/Users/myName/Documents/myTemplatePath // 

For more information regarding these commands, see the MEL Command reference.

Environment variables set within the Maya command line are only saved for the current instance of Maya.
