Updating from earlier versions

Updating the Unreal Engine SDK

If you are not using a version control system like Git on your project, we recommend backing up your whole project before updating the Unreal Engine SDK.

When you update the Unreal Engine SDK, we recommend that you delete the plugin completely and then re-add it to the project as follows.

1. Close the Unreal project if it is currently open.

2. Delete the ReadyPlayerMe and glTFRuntime folders located in the PROJECT/Plugins/ folder.

3. Download the latest version of the Unreal SDK.

4. Extract the contents of downloaded ZIP file (ReadyPlayerMe and glTFRuntime folders) into your PROJECT/Plugins/ folder.

5. Reopen to project and when the popup opens, click Yes rebuild the modules.

If you are unable to compile or open the project after upgrading the plugins, or get a message to manually rebuild, delete the following generated files and reopen the project. You need to close the IDE and stop the Engine and all associated processes in order to be able to remove these files and folders.

• Binaries folder

• Intermediate folder

• Saved folder

• If present, the Visual Studio file ending in ".sln"
