Open your Unity project
This page describes how to configure your projects through the Hub before you open them in the Unity Editor. To open a project with the default settings, select the project in the project list and it opens in the Unity Editor.
Open with a different Editor version
To open a project with a different version of the Unity Editor, click on the Editor version of the project. This opens a modal with a list of all the Editor versions installed.
To install a new Editor version, select Install Editor version in the bottom left corner of the modal and then click on Install to start the download and installation of the Editor.
Note: When you open a project with a different Editor version, a warning screen pops up to notify you of possible issues. Select Change version to continue.
Add command line arguments
To add command line arguments to a project, select the contextual menu icon (three horizontal dots) to the right of the project or right-click the project. In the dropdown menu select Add command line arguments.
Command line arguments can be entered into the text area and then will be saved once the Save button is selected. Click on the external link at the bottom left of the modal to open the Command line arguments documentation.
For a list of the arguments you can use when you launch a version of the Unity Editor, go to the Unity Editor command line arguments page of the user manual.
