How are floating licenses retrieved?

This section describes how floating licenses are retrieved.
  • When you are in GUI mode, a GUI license is checked out. If none are available, the plugin runs in demo mode.
  • Render mode occurs when you run a host program with no GUI. If you are in render mode for any of the hosts that support floating licenses, the following license checkouts are attempted:
    1. if a GUI license is checked out for the machine, then that license is used to render (that way you don’t check out a GUI and a render-only on the same machine if someone is already using an interactive license on the machine).
    2. if no GUI license is checked out for the machine, then a render-only license is checked out.
    3. If the environment variable RVL_NOGUI_LIC is not set, then if no-render only licenses are available after step 2, then a GUI license is checked out (if available) for the render-only process. (You should know this, in case you fire up too many renders, then you may find yourself without a GUI license to use!). As such, GUI licenses may be used in a render-only context, but then the GUI license is not available for another machine. So what this means is that at the end of the day, if everyone is finished with their GUI licenses, then you can use all render AND GUI license to render with.
    4. When the environment variable RVL_NOGUI_LIC is set to YES, instructs the plug-in to NOT check out a GUI license if a render-only license is not available, overriding the default behavior ( for supported plug-in versions only, see below).
    5. Furthermore, when the environment variable RVL_QUIT_LIC_FAIL is set to YES,  instructs the plug-in to terminate rendering if a license is not available in a render-only context, instead of drawing the demo watermark (for supported plug-in versions only, see below).
Supported products for the environment variables RVL_NOGUI_LIC and RVL_QUIT_LIC_FAIL :
  • OFX products, minimal versions: DE:Noise v2.2, RSMB v5.1.1, Twixtor v6.1.1, RE:Match 1.3, DEFlicker 1.0, RE:Map 3.0. Note that RVL_QUIT_LIC_FAIL will also cause the plug-ins to terminate rendering if a GPU error is encountered (instead of drawing a green frame).
  • Fusion native products, minimal versions: RSMB v5.0.1, Twixtor 6.0.1, RE:Flex 5.1
  • After Effects-compatible minimal versions: Twixtor 6.2, RE:Flex 5.2, RSMB 5.1, RE:Match v1.4, DEFlicker 1.4, DE:Noise 3.1, RE:Map 3.0, RE:Lens 1.0. Note that RVL_QUIT_LIC_FAIL will also cause the plug-ins to terminate rendering if a GPU error is encountered (instead of drawing a green frame).
