Environment Variables

...

You can include environment variables in the form ${VAR_NAME} which are replaced with the value of the respective environment variable during rendering. For example, if the file name is specified as${TEX_PATH}/${PROJ_FOLDER}/mytexture.exr, then V-Ray will look up the environment variables TEX_PATH and PROJ_FOLDER and replace the tags with their values. Suppose that TEX_PATH is set to c:/textures and PROJ_FOLDER is set to proj1, then the final bitmap file name will be expanded as c:/textures/proj1/mytexture.exr
