Debugging TextMesh Pro text

Use the Text Info Debug Tool to display diagnostic information about a TextMesh Pro GameObject in the Scene view and the Inspector.

For example, you can display lines that indicate font metrics such as the line height, or the offset for superscript and subscript text. This can help you diagnose problems with fonts you import.

The TextMesh Pro debug tool set to show character bounding boxes and font metrics

[NOTE!] The debug tool is part of the TextMesh Pro Examples & Extras package. You can install the package from the menu (select Window > TextMesh Pro > Import TMP Examples and Extras) or the TextMesh Pro settings.

To use the debug tool:

1. Open a TextMesh Pro GameObject in the Inspector.

2. Add a TMP_TextInfoDebugTool component.

3. From the TMP_Text Info Debug Tool section, turn debug settings on and off. You can see the results in the Scene view.
