Example UI Requires TextMeshPro Essentials


Mailbox supports Legacy UI, but all example UI elements use TextMeshPro, as Unity's old UI Text is now legacy. To view the examples, install TMP Essentials (Window โ†’ TextMeshPro โ†’ Import TMP Essential Resources).


All components support TextReferences, so if you prefer Legacy UI, you can switch to using Text instead of TMP.
