Manage licenses with the new Arnold License Manager
There’s a new Arnold License Manager that provides a user interface for:
- Signing in (and, if necessary, installing the necessary single-user licensing components)
- Maya and 3ds Max users may also sign in in the main application.
- Switching between single-user and network licensing
- Connecting to network license servers
- Getting diagnostics
- Installing the Autodesk Network License Manager (super helpful for macOS, where it sets up a plist daemon to automatically restart lmgrd)
The Arnold License Manager is available from the Arnold > Licensing menu in Maya, 3ds Max, Houdini, CINEMA 4D, and Katana.
You can also run the Arnold License Manager from the command line.
Monthly subscription purchased from the Autodesk e-store use Sign In activation.
Arnold renders in evaluation mode with a watermark if you don't have a license. For production rendering, you need a license.
If you use Maya or 3ds Max, you don't need an Arnold license to render without a watermark in the user interface. You do need an Arnold license to do any batch rendering because that happens outside of the Maya or 3ds Max user interface.
If you use CINEMA 4D, Houdini, or Katana, you need an Arnold license to remove the watermark from your IPR renders in the user interface.
Arnold licenses allow you to render without a watermark
Arnold licenses are floating licenses (also known as "network licenses" or "multi-user licenses")
Floating licenses allow any computer on the network to render with Arnold. The maximum number of computers that can render at the same time (concurrently) is determined by the license count. For example, if you have five Arnold licenses, then at most five computers can be rendering at the same time.
Floating licenses require a license server, which manages your use of Arnold through a license key. The license key typically defines the version of Arnold you can use, the number of computers you can use for rendering, and for how long.
Licenses are per-machine
Arnold licenses are per-machine, and there is no restriction on the number of cores or threads used to render. With one license, you can render on as many threads as you want.
You can run multiple Arnold render jobs on a single machine, and they will all share the same license.
Free Arnold plugins
Arnold plugins (such as MtoA, HtoA, SItoA, C4DtoA, KtoA, and MAXtoA) do not require a license. You can install and use any of the Arnold plugins. An Arnold license is required only when you want to render without watermarks.
Licenses are global
Arnold's license usage is not restricted to a territory or region.
Floating licenses can be used by computers at multiple geographic locations (as long as they can connect to the license server), and node-locked licenses can be used anywhere (for example, a node-locked license on a laptop can travel with the laptop).
Render farm licensing
Every node on a render farm needs an Arnold license. This includes TeamRender clients for CINEMA 4D.
