Installing Unity and the Cluster Creator Kit

In this article, we will introduce the necessary tools for creating and uploading a world.

Specifically, we will be going over the steps to install Unity and Cluster Creator Kit.

What is the Unity Game Engine?

Unity is a 2D/3D game engine developed and provided by Unity Technologies.
Other than being used for game creation, it is used in various fields such as manufacturing industries, video production and anime production, and construction industries.

For cluster, Unity is used to produce and upload virtual spaces.
Unity can be used free of charge if used for personal and non-commercial purposes.

Please refer to the official Unity website for more information.

What is the Cluster Creator Kit?

The “Cluster Creator Kit” (referred to as CCK in the following sections) is an development kit distributed by Cluster, Inc.
By installing CCK into Unity, you will be able to easily produce and upload your worlds to cluster.

There are also items, triggers, and gimmicks included in CCK to build various experiences.

Installing Unity

Install Unity Hub (Useful for Managing Versions and Projects)

Now, let us prepare the tools to begin creating a virtual space.

First, install Unity.
We recommend using “Unity Hub” for installing Unity!

Unity Hub is a management tool to manage all Unity projects and versions.
By using Unity Hub, the complex organization of components and projects can be easily done.

Going on to the specific steps:

  • First, open the Download page for Unity.
  • Click on the Download button and download the file for Unity Hub

You have now installed Unity Hub.

Install Unity Version Supporting the Cluster Creator Kit onto Unity Hub

This page will have tabs indicating “Unity 2022.X”, “Unity 2021.X” and so on. These consist of various versions of Unity.
Unity is frequently being updated and although there are new features added with later versions, projects may not be supported with the latest versions.

  • Install the version of Unity supporting CCK

Attention: Please use the recommended version of Unity stated in the Creator Kit Document (Updated 2022/7/18: Unity 2021.3.4f1). Please note, versions other than the recommended lead to the inability to join the world once uploaded.

  • Click on “Unity 2021.X” and scroll to “Unity 2021.3.4f1”. Click Unity Hub to the left of the version title and open Unity Hub.

Question: Is 2023.3.4f1 and 2023.3.4 two completely different versions?
Answer: They’re the same!

  • Once Unity Hub is open, select the appropriate OS and add the following modules.
  • For Windows
    • Android Build Support
    • iOS Build Support
    • Mac Build Support (Mono)
  • For macOS
    • Android Build Support
    • iOS Build Support
    • Windows Build Support (Mono)
  • Tick the necessary boxes and click INSTALL on the bottom right.

Now, you are done with installing Unity!
