Introduction
As we advance to a new Unity version and update to the latest 3D Studio SDK, it’s important to follow the correct upgrade process to ensure a smooth transition.
Note: If you're starting a new project from scratch, there's no need to upgrade anything. Simply download the latest Unity version we’re using and install the new SDK as usual.
Removing the SDK Package
Before upgrading to the new Unity version, it's crucial to remove the old SDK package from your project, as it is incompatible with the updated version.
In the top menu, click on the Window tab.
From there, navigate to Package Manager.
In the left panel, select Frontline SDK.
Click Remove in the top right corner.
This will remove the SDK package from your project.
After completing this step, close Unity, as the next step involves upgrading your Unity version.
Before continuing, you'll need to download the correct Unity version for the new Frontline 3D Studio SDK. For detailed instructions, please follow: Installing Unity
Changing the Unity Version of the Project
After downloading the correct Unity version (2022.3.13f1) along with all the relevant modules, you’re ready to update your project's Unity version.

On the right side of your project’s line, click on the Editor version option.
A menu will appear, allowing you to choose which version of Unity you want to use to open your project.
