Notes

Anchor
std_note_1
std_note_1
1.VRAY_AUTH_CLIENT_FILE_PATH needs to point to the folder that contains the vrlclient.xml  file that holds the V-Ray license server settings (IP address and port number). Alternatively, using the tool to set or change your license settings will create the vrlclient.xml file for you at a default location and there will be no need to explicitly define its location the VRAY_AUTH_CLIENT_FILE_PATH variable. However, it might be useful to use the variable to define per-user license settings.
