Build an Epic Unreal Engine conda package for Deadline Cloud - Deadline Cloud

Build an Epic Unreal Engine conda package for Deadline Cloud

The unreal-engine conda recipe builds an Epic Unreal Engine conda package.

Unlike other recipes in this repository, this one is designed to be built locally on a machine where Unreal Engine is already installed. Unreal Engine packages are large (UE 5.6 is approximately 20 GiB across about 80,000 files), so submitting them to a queue as a job attachment is impractical.

To use the recipe:

  1. Install Unreal Engine on your Windows machine. The default source path in the recipe is the Epic Games Launcher path C:\Program Files\Epic Games\UE_5.6. Adjust recipe/recipe.yaml for your version or custom source build location.

  2. Install rattler-build and enable Windows long path support.

  3. Build and publish the package to your conda channel:

    rattler-build publish path-to-recipe-file --to publish-conda-channel

The recipe README includes step-by-step instructions for adapting it to your Unreal Engine version, including custom source builds.

The samples repository also includes unreal-engine-openjd, which builds the Unreal Engine Open Job Description adaptor with rattler-build for Windows and Python 3.13.
