Don't think there is any such book specifically for UE and its source. But there's a lot of good books on realtime rendering and graphics programming in general. GPU Gems, Shader X and GPU Pro are good series for learning specific graphics programming techniques. https://developer.nvidia.com/gpugems/GPUGems/gpugems_pref01.html https://developer.nvidia.com/gpugems/GPUGems/gpugems_pref01.... http://www.realtimerendering.com/resources/shaderx/ http://www.realtimerendering.com/resources/shaderx/ For a general game engine overview: Game Engine Architecture by Jason Gregory (Naughty Dog) Game Programming Patterns: https://www.amazon.co.uk/Game-Programming-Patterns-Robert-Nystrom/dp/0990582906 https://www.amazon.co.uk/Game-Programming-Patterns-Robert-Ny...

It's fun to explore the source though, and NVIDIA has some cool experimental branches of the engine with their stuff integrated. https://github.com/NvPhysX/UnrealEngine https://github.com/NvPhysX/UnrealEngine
