Navigate to the root directory of your Unreal project using a file management system or command line and create a Plugins folder, if you don’t already have one.
Unzip the downloaded file and copy the SequencePlugin folder into your project’s Plugins folder.
Launch your project, then allow it to update the UProject Settings.
To find the SequencePlugin content folder in your content drawer enable show plugin content: Content Drawer > Settings > Show Plugin Content
Before updating, please backup any configuration data stored in PluginConfig/Config.h or Config/Config.h. Once backed up, delete the entire SequencePlugin directory. Replace it with the new updated version of the plugin.If your project is currently on 5.2 or 5.3, then for this version you’ll want to upgrade to 5.4.
Close the Unreal Editor and your your Code Editor
Right click on your Unreal Project file > “Switch Unreal Engine Version” (you may need to click “Show more options”), choose 5.4 and confirm
Open your code editor and rebuild your source code
As a way of future proofing we recommend installing Visual Studio 2022 in accordance with these docs as Unreal 5.4 and onward will be dropping support for Visual Studio 2019.
