In this chapter, you learned how to create a 3D UI root. We saw how to calibrate the 3D UI's scale to match the screen's pixel size.

We created a 3D score counter that scales up before it increases gradually towards the new score value. Anchors were used to make sure it is visible in most common screen sizes and aspect ratios.

A specific 3D pause menu was created with an interaction override collider to avoid interactions with the game while it's paused, using Time.timeScale = 0.
