How to Update the License

After the license expires, you can update it using the following methods:

  • Update the license within the UE Editor, which is typically applicable during the development process.
  • Use Blueprint functions to update the license, which can be used to develop an automated license update program.
  • Manually update the license, which is the most basic update method.

Tip

Updating the license in the UE Editor and Blueprint requires the plugin version to be no lower than 2022.1.1.20230718.

The following sections will describe each method in detail.

Update License Using Blueprint

You can update the license by using either the Update License By File function or the Update License By Content function.

The difference between these two functions is as follows:

Update License By File
This function updates the license by providing a file from the local disk (full path).

Update License By Content
This function updates the license by providing the contents of the license file.
This is particularly useful when the license content is returned via an HTTP request.

Tip

C++ users can access these two Blueprint functions through the UM4ULicenseBlueprintLibrary class.

Manually Update the License

Navigate to the directory Plugins\MediaPipe4U\Source\MediaPipe\license and replace the mediapipe4u.license file.
