BYG Rich Text Library

This plugin for Unreal Engine 4 is an alternative to UE4's built in rich text system.

It differs from Unreal's default rich text implementation in a few ways:

• Support for Markdown and customizable markup.
• Support for nested styles.
• Simple to extend supported text properties in C++.
