Yes. Switch to Outline Neon and use Load Outline Font to select your own TTF or OTF font. You can preview fonts before applying them and save favorites in your scene.

Multilingual text is supported when the selected font contains the required characters and Blender supports their text shaping. Built-in Tube Neon supports uppercase Latin and Cyrillic, numbers and punctuation.

Fonts are not bundled or automatically packed into your project. Keep the original font file accessible when transferring the project or editing the text later.
