TextMeshPro NullReferenceException

Error message

NullReferenceException: Object reference not set to an instance of an object
TMPro.MaterialReference..ctor (...)

What’s causing this

The HeroBridge Standalone example scene uses TextMeshPro for UI text. This error happens when TextMeshPro Essential Resources haven’t been imported into the project.

Without these resources, TextMeshPro can’t properly initialize its materials, which results in this NullReferenceException.

Fix: Import TextMeshPro Essential Resources

  1. Open Unity’s top menu Window → TextMeshPro → Import TMP Essential Resources

  2. Let Unity finish importing the files.

  3. Close the affected scene.

  4. Reopen the scene.

In most cases, this resolves the error immediately.

Don’t want to use TextMeshPro?

If you prefer not to use TextMeshPro at all, you can replace the TextMeshPro components in the example scenes with Legacy Text UI instead.

This avoids the dependency entirely.
