HELIX is in Early Access Preview. Some features and documentation may be non-functional or out of date.

Install Creator Kit#

The Creator Kit is an Unreal Engine plugin released by HELIX to package custom assets to be imported into HELIX worlds. Some very basic knowledge of the Unreal Engine 5 Editor is recommended before using Creator Kit. There are plenty of high-quality tutorials online covering the basics of UE5, such as this Unreal in 100 Seconds video.

Install Unreal Engine & Creator Kit plugin#

Creator Kit requires a copy of UE5.5 to function. You can install both for free.

  1. Install Unreal Engine 5.5 from Epic Games Launcher

  2. IMPORTANT: Make sure to select 5.5.x from the dropdown list. Creator Kit will NOT work if you install an older or newer version of UE5 (i.e. UE5.7.0)

  3. [screenshot of 5.5 selection in Launcher, emphasize 5.5 version]

  4. Download Creator Kit: Download Link

  5. Open CreatorKit.uproject using UE5.5.

📦 Create a New Package#

Creator Kit can be used to package any Unreal asset for use in HELIX. This includes (but not limited to) the following asset types. Follow the linked tutorials below to import and use your desired asset type.

Use the HELIX Packing Tool from the main toolbar to create and manage packages.

Important Tips#

Ensure ALL Referenced Assets Are Inside The Package Folder#

When you create a new package using Creator Kit, it will create a new folder in the Content Browser with the selected package type and name (i.e. "Addon_MyFirstPackage").

Ensure that every asset is contained within this folder, otherwise it will cause your world to break and clients to crash. Be extra careful when you are migrating assets from Fab or another Unreal Engine project, as by default Unreal will copy the assets into the root /Content folder. In the Migrate > Select Folder dialog, make sure to select the /Content/Addon_MyFirstPackage folder. Any references to assets that are outside the package folder will result in a crash.

Package Types#

A single HELIX package can contain several assets of the same or different asset type (i.e. An "Addon" type package can contain blueprints, static meshes, materials, effects). However, if you select a specific package type upon creation such as Vehicle or Map, Creator Kit will only cook/package assets that are directly referenced by the selected "default asset". This may result in some of assets that are present in the Content Browser package folder to be missing from the packaged Pak file.

Recommendation: Select the "Addon" package type if you want every asset in the Content Browser package folder to be included in the packaged Pak file.
