Select the appropriate branch for your deployment:

Branch Stability Use Case Recommended For
release ✅ Stable Production Most users
mainline 🔄 Latest features Development/Testing Advanced users

💡 Tip: Use the release branch for production environments to ensure stability.

Create a new Windows EC2 instance to install Unreal on (Optional)

If you’re setting up on a brand new Windows EC2 Instance as your submitter, a g5.2xlarge instance with 200 GB of storage will likely be reasonable minimum:

  1. Launch EC2 instance with a valid Instance Profile. This is required to download NVIDIA GRID drivers as instructed below.
  2. Download the Epic Installer and install a supported version of Unreal (5.4 - 5.6).
    • UE 5.5 has a known crash bug when running with the DirectX 11 plugin, see UI issue #UE-276282. If you need DirectX support on UE 5.5, use DirectX 12+.
  3. NVIDIA GRID drivers - Follow Windows instructions - https://docs.aws.amazon.com/AWSEC2/latest/UserGuide/install-nvidia-driver.html#nvidia-GRID-driver

Submitter Installation

If you're using an AI coding agent, you can automate the entire setup below by running the ue-dev-setup skill. Just ask: "use ue-dev-setup skill to setup this computer". The agent will handle as much as it can and prompt you only when manual action is needed.

If you prefer to set up manually, expand the section below.

Manual Setup Steps ## Windows Long Paths Many of the steps below may attempt to create files which exceed the default Windows maximum path length. Before attempting to build and install the Deadline Cloud for Unreal Engine submitter or adapter on a Windows machine you are strongly encouraged to enable Windows Long path support by following the instructions in one of the options from [this page](https://learn.microsoft.com/en-us/windows/win32/fileio/maximum-file-path-limitation?tabs=registry), such as by running the PowerShell command [here](https://learn.microsoft.com/en-us/windows/win32/fileio/maximum-file-path-limitation?tabs=powershell#tabpanel_1_powershell). Additionally there's currently an [open issue on the worker agent](https://github.com/aws-deadline/deadline-cloud-worker-agent/issues/520) due to a dependency which doesn't ship properly configured to support Windows long paths. When setting up your workers you MUST follow the workaround steps described in the linked issue to fully support Windows long paths until the issue is resolved. ## Install Build Tools The Unreal Submitter Plugin currently must be compiled locally. 1. Install Visual Studio using the Visual Studio Installer from https://visualstudio.microsoft.com/ 1. Verify your Visual Studio and build tools version are compatible with your version of Unreal by checking the table [here](https://dev.epicgames.com/documentation/en-us/unreal-engine/setting-up-visual-studio-development-environment-for-cplusplus-projects-in-unreal-engine?application_version=5.5) 1. Under "Individual Components", ensure that the MSVC build tools version selected ("Latest" by default) matches the recommended version in the table. Even though the compatibility guidance may suggest a version "or later", build errors sometimes occur when using a newer version than the one listed as "recommended". 1. Under "Individual Components", select a recent .NET Framework SDK (4.6.1 and 4.8.1 have been verified) 1. Under "Workloads" select "Desktop development with C++" ## Install Deadline Cloud Monitor Deadline Cloud Monitor is used to both manage your credentials for submitting jobs to Deadline Cloud as well as monitoring the status of your jobs. 1. Follow the instructions at https://docs.aws.amazon.com/deadline-cloud/latest/userguide/submitter.html#install-deadline-cloud-monitor 1. Sign in ## Environment Setup 1. (If not already installed) Install a recent version of Python for all users (3.12 has been verified) 1. Make sure your Environment Variables are set correctly. In System Environment Variables, your PATH should include: - The path to your Python Installation (C:\Program Files\Python312 for example) - The path to your Python Scripts folder (C:\Program Files\Python312\scripts for example) - The path to your Unreal binaries (C:\Program Files\Epic Games\UE_5.5\Engine\Binaries\Win64) ## Deadline Software Installation - clone or download `deadline-cloud-for-unreal-engine` either from the release branch or mainline depending on whether you'd like the most recent tested release or all of the most recent commits. 
git clone https://github.com/aws-deadline/deadline-cloud-for-unreal-engine.git
cd deadline-cloud-for-unreal-engine
git switch release
## Optional - Build and Install Plugin with script A helper script exists at scripts/build_plugin.py which will optionally automate the next 2 steps for you. It will attempt to find the latest version of Unreal, build your plugin and python dependencies, and install them in the correct locations. Settings like the Unreal version to use can be overridden. See the full help list with: 
python scripts/build_plugin.py -h
To build and install your current copy of deadline-cloud-for-unreal-engine as a submitter with the latest Unreal Engine installation, run: 
python scripts/build_plugin.py --install
If you've installed with this script successfully, you can now skip to "Submitter Installation Complete" ## Build the Plugin Adjust the first two paths below based on where your installation of Unreal lives, and where you installed deadline-cloud-for-unreal-engine. From the Unreal Install Batchfiles Folder (Note the ‘package’ parameter can be any new directory, however you’ll want it to be called "UnrealDeadlineCloudService" later): 
cd C:\Program Files\Epic Games\UE_5.5\Engine\Build\BatchFiles
runuat.bat BuildPlugin -plugin="C:\deadline\deadline-cloud-for-unreal-engine\src\unreal_plugin\UnrealDeadlineCloudService.uplugin" -package="C:\UnrealDeadlineCloudService"
- Copy the "package" folder above to your Unreal installation’s Plugins folder (C:\Program Files\Epic Games\UE_5.5\Engine\Plugins\UnrealDeadlineCloudService for example) ## Python Dependencies There are 4 ways to install the required Python dependencies. _1._ If you've built and installed the plugin from the release branch above, you can simply install from pip. Use the following install command, adjusting the paths to your Unreal installation: 
"C:\Program Files\Epic Games\UE_5.5\Engine\Binaries\ThirdParty\Python3\Win64\python" -m pip install deadline-cloud-for-unreal-engine --target "C:\Program Files\Epic Games\UE_5.5\Engine\Plugins\UnrealDeadlineCloudService\Content\Python\libraries"
_2._ Alternatively in your .uplugin file (In the above steps this would live at C:\Program Files\Epic Games\UE_5.5\Engine\Plugins\UnrealDeadlineCloudService\UnrealDeadlineCloudService.uplugin) you can add a "PythonRequirements" section which matches the latest release of deadline-cloud-for-unreal-engine in GitHub/PyPi, for example: 
    "PythonRequirements":
    [
        {

            "Platform": "All",
            "Requirements":
            [
                "deadline-cloud-for-unreal-engine>=0.5.0"
            ]
        }
    ]
Note that you may wish to disable the "strict hash" feature in Unreal's Python settings, or add hash settings for specific library and dependency versions you wish to consume. _3._ If you're pulling from mainline you may have python dependencies which are not yet released to PyPi - you'll need to build and install your local copy which can be done with hatch. Note that the .whl file will need to be changed to reflect the version which is output by hatch build: 
// Install hatch if not yet installed
pip install hatch
hatch build
"C:\Program Files\Epic Games\UE_5.5\Engine\Binaries\ThirdParty\Python3\Win64\python" -m pip install dist\deadline_cloud_for_unreal_engine-0.2.2.post21-py3-none-any.whl --target "C:\Program Files\Epic Games\UE_5.5\Engine\Plugins\UnrealDeadlineCloudService\Content\Python\libraries"
_4._ Lastly, Python dependencies can be installed by the submitter installer. NOTE - these may be out of date with your code above from the release or mainline branch, and this method should not currently be preferred. 1. Download submitter installer from Deadline Cloud AWS Console’s Downloads Tab or from within the Deadline Cloud Monitor under Workstation Setup -> Downloads 1. Run, install for all users. Default install location is fine. 1. Enable the Unreal Engine Plugin 1. Make sure the Unreal Engine plugin install path matches where your plugin was copied to (In particular make sure your Unreal version matches)

Create a Fleet

If you already have a Windows fleet and don't need to set up a new fleet, you can stop here or skip down to the "Submit a Test Render" section.

Create a Service Managed Fleet (SMF)

  1. Follow Service-managed fleets user guide to create a Service Managed Fleet (SMF) if you don't already have one. On Service Managed Fleets (SMF), the Unreal Engine and adaptor are automatically available via the deadline-cloud Conda channel with the default Queue Environment. You are ready to start rendering now! Continue with "Submit a Test Render" section below to submit a test render job.

Create a Customer Managed Fleet (CMF)

  1. Follow Create a customer-managed fleet to create a Customer Managed Fleet (CMF) if you don't already have one.
    1. :warning: When associating your CMF to queues, remove the default Conda queue environment if you do not use it. This will prevent the Conda environment from being used and accidentally using the default SMF specific variables for jobs submitted to your CMF. If you use Conda in your CMF, remember to update "CondaPackages" and "CondaChannels" variables in "Parameter Definition Overrides" during job submission.
  2. Follow Worker host setup and configuration to set up a worker host.
  3. Follow Manage access to Windows job user secrets to set up the Windows job user secrets for your CMF worker.
  4. Follow Install and configure software required for jobs to install the software required to run jobs.
  5. Follow CMF Worker Setup Guide to set up your worker node to run Unreal Engine jobs.
