If you are upgrading your Unreal Engine project from a previous version of Unreal to Unreal 5.1 for streaming on the PureWeb Reality platform, please follow the steps below.

  1. Create a backup of your current project before proceeding to step 2.
  2. Open your current Unreal project.
  3. If you are using a PureWeb plugin version that requires the use of the PureWeb Actor, remove the actor and references to it from your project.
  4. Navigate to the Plugins dialog and disable the PureWeb plugin.
  5. Save these changes and close the Unreal Editor
  6. Navigate to your project folder in the Windows File Explorer.
  7. Delete the existing build, saved and cached folders (see Figure 1 below):
    - Binaries
    - Build (if you are building to a custom location, remove that folder as well)
    - DerivedDataCache
    - Intermediate
    - Saved
  8. Navigate into the /Plugins/ folder and remove the PureWeb directory.
  9. Upgrade your Unreal project to UE 5.1.
  10. Open your upgraded project, create a build and run it to ensure everything still works.
  11. Follow the Prepare your Unreal 5.1 project instructions to configure your project for streaming on the PureWeb Reality platform.
