Description:
TextMeshPro is the ultimate text solution for Unity. It's a perfect replacement for Unity UI Text and legacy Text Mesh.
The powerful and easy-to-use TextMeshPro (also known as TMP) uses advanced text rendering techniques along with a set of custom shaders; it dramatically improves visual quality while giving users incredible flexibility in creating text styles and textures.
TextMeshPro provides greater control over text formatting and layout, providing character, word, line and paragraph spacing adjustments, kerning, text alignment, links, over 30 rich text tags, multiple fonts and sprite support, custom styles, and more Function.
Powerful performance. This improved visual quality and flexibility comes at no performance cost since TextMeshPro creates geometry using the same two triangles per character as Unity's text components.
