Modding
The Onsets Scripting API is what other games call "modding". Since scripting is the main feature of Onsets, Onset can be seen as modding "by default".
This guide is just for how to import additional 3D models to Onset.
Workflow
Onset uses the Unreal Engine and therefore uses it's modding pipeline to load additional content.
You can import any 3D models from any 3D program into Unreal (FBX, OBJ). Unreal will create a .pak file out of your assets that can then be loaded in Onset.

Install Unreal Engine
You first need to install the Unreal Engine. See the above table for what version is required.
https://docs.unrealengine.com/en-US/GettingStarted/Installation/index.html
Setup project
After installing the Unreal Engine, download the SDK for the correct engine version from above.
Extract the OnsetModding folder to your Unreal Projects folder. It's usually located in your Documents folder.
Double click on the OnsetModding.uproject. It will open the Unreal Engine.
Go to Edit -> Plugins
Select "New Plugin"
Select "Content Only". Enter a mod name. Make sure "Show Content Directory" is ticked. Then click "Create Plugin". The name of the mod is really important as we need that later one. So remember that.
You will see this message.
Introduce Content
Open the Content Browser.
Click this icon to get a folder overview.
All files that you import will need to be placed inside your mod content folder (MyFirstMod).
If you are familiar with Unreal then you can skip this:
Import3DModel
You can also watch any Unreal tutorial on YouTube on how to add and setup your models in Unreal.
Package your content
Open the Onset Pak Creator window.
- Select your mod from the left side.
- Click 'Browse' to select a location where the .pak file will be placed. For example D:\OnsetModPackage
- Click Create .pak
The packaging process can take a moment. When it's done you will find the .pak file in your specified folder.
To view the contents of your .pak file you can use the UnrealPak tool. It is located under C:\Program Files\Epic Games\UE_4.23\Engine\Binaries\Win64
