Xengine (también conocido como XenEngine) es una rama de terceros del Source Engine utilizando código licenciado. Es una versión modificada de la rama de motor Source 2013 Multiplayer con adiciones de Team Fortress 2, cuyo desarrollo fue influenciado por las limitaciones del Source Engine. Aunque inicialmente solo se planeó CSM, Crowbar Collective consiguió mucho más conocimiento mientras trabajaban en el motor, lo que les permitió para mas experimentación y mejoras, eventualmente llegando a la introducción de un sistema de iluminación completamente nuevo, y  deferred lighting. Además de utilizar la versión del motor Team Fortress 2 como base, esta versión también es un hibrido de las versiones de motor Portal 2 y Left 4 Dead.

Features

• Engine
  • Entity and Displacement Limit upgraded from 4k to 8k.
  • Backported a lot of optimizations and some entities from Left 4 Dead and Portal 2 that Team Fortress 2 doesn't have.
  • Improved AI, whose behavior depends on the current difficulty level (some NPCs also support Main and Assault Behavior Trees from the ai folder).
  • Temp lights were swapped with new deferred lights.
  • Gbuffer that allowed the addition of some modern, difficult-to-make effects.
  • Made from scratch Qt UI with the ability to be customized and add new stuff with no limitations (VGUI can be reenabled with -oldgameui launch parameter).
  • Using  Fast Approximate Anti-Aliasing (FXAA for short) instead of  MultiSample Anti-Aliasing (MSAA) for anti-aliasing, which reduces performance and does not work correctly on Xengine's deferred lighting (unlike FXAA).
  • New and extended Post Processor.
  • Native Linux support.
  • Enhanced multiplayer with fixes for the client and server.
  • Dynamic music system.

• Visuals
  • 4Way blends with support for 4 bumpmaps and tri-planar mapping, enabling all the options from other material shaders.
  • Cascaded Shadow Mapping with PCF-based soft shadows and viewmodel self-shadowing.
  • Parallax Occlusion Mapping.
  • Procedural Moss.
  • Deferred lighting.
  • Dynamic lighting system with PBR-based lighting and speculars.
  • Light cookies for both new point light and new spot light, the last can be animated.
  • Support for up to 2K dynamic lights per scene and all rendering features on secondary render targets (reflection/refraction, monitors, TV screens, etc.)
  • Upgraded flashlight using the new deferred lighting system.
  • Godrays with disk for both the sun and local lights (which also support the "Fancy" godrays type).
  • Screenspace Fog ("Xog"), that can be applied globally or locally using cuboid/ellipsoid volumes.
  • Soft particles.
  • Flowing water.
  • Cinematic lens flares.
  • Upgraded tonemapping with bloom which uses a modified version of the Reinhard filter.
  • Optimized shaders for faster compilation and better runtime performance.
• Tools
  • In-game new lights and xog editors.
  • Multiple VRAD upgrades, such as support for Alpha-Tested textures, 4-way blends, baked Ambient Occlusion, Real Sky Ambient Light, and more.
  • 64-bit shader compiler.
