* ROBUST DYNAMICS & CONSTRAINT SOLVING - Supports a wide variety of useful game-ready constraint types including ragdolls. Is also fully customizable. * BATTLE-TESTED COLLISION DETECTION - Highly robust, for continuous collision detection for environments, characters and vehicles. * COMPLETE PRODUCTION-READY TOOL CHAIN - Extensible asset conditioning pipeline with full plug-in support for Autodesk, 3ds Max, and Maya. * VISUAL DEBUGGER - Displays and records on-target profiling and debugging data and real-time multi-threaded performance data.

* Unreal Engine 4 supports advanced DirectX 11 & 12 rendering features such as full-scene HDR reflections, thousands of dynamic lights per scene, artist-programmable tessellation and displacement, physically-based shading and materials, IES lighting profiles and much more. * Cascade's pipelined includes fast, low-cost GPU particle simulation and a collision system that interacts with the depth buffer. Millions of dynamic particles can receive and emit light within a scene, and you can control all kinds of particle properties, including size, color, density, falloff and bounciness. * Quickly create a wide range of surfaces that hold up visually under close examination. Layer materials and fine-tune values at the pixel level to achieve any kind of style you desire. * Bring your creative visions to life in-game with Blueprint visual scripting. Blueprints enable anyone to rapidly prototype and build playable content without touching a line of code. * Blueprint visual scripting comes with a built-in debugger you can use to interactively visualize gameplay flow and inspect property values while testing your game. * Use Unreal Engine 4's Content Browser to import, organize, search, tag, filter and modify terabytes of game assets within the Unreal Editor. Real-time animated thumbnail previews can easily be changed and saved with the handy screenshot function. * Use the Persona animation toolset to edit skeletons, skeletal meshes and sockets, animation Blueprints and more. This multi-purpose tool enables you to preview animation sequences and morph targets, and also set up animation blend spaces and montages. * Unreal Engine 4's Matinee cinematic toolset provides director-level control over cut scenes, dynamic gameplay sequences and movies.
