XenEngine

Xengine (also known as XenEngine) is a third-party Source Engine branch using licenced code. It is a modified version of the Source 2013 Multiplayer engine branch with Team Fortress 2 additions, whose development was influenced by the limitations of the Source Engine. Although initially only CSM was planned, they gained much more knowledge while working on the engine, which allowed for more experimentation and improvements, eventually leading to the introduction of a completely new lighting system, and  deferred lighting.
