CryEngine (stylized as CRYENGINE) is a game engine designed by the German game developer Crytek. It has been used in all of their titles with the initial version being used in Far Cry, and continues to be updated to support new consoles and hardware for their games. It has also been used for many third-party games under Crytek's licensing scheme, including Sniper: Ghost Warrior 2 and SNOW. Warhorse Studios uses a modified version of the engine for their medieval RPG Kingdom Come: Deliverance. Ubisoft maintains an in-house, heavily modified version of CryEngine from the original Far Cry called Dunia, which is used in their later iterations of the Far Cry series. The Dunia engine would in turn be further modified and used in games such as The Crew 2.[7]

According to various anonymous reports in April 2015, CryEngine was licensed to Amazon for $50–70 million.[8] Consequently, in February 2016, Amazon released its own reworked and extended version of CryEngine under the name of Amazon Lumberyard.[9][10] In June 2021, through Amazon Lumberyard, the open-source Open 3D Engine is based on CryEngine.

Versions

[edit]
This diagram illustrates the development history of CryEngine game engine versions.

CryEngine 1

[edit]

CryEngine 1 was first made and used for the first-person shooter video game Far Cry. It was originally developed by Crytek as a technology demo for Nvidia and, when the company saw its potential, it was turned into a game. When video cards with support for 3.0 pixel and vertex shaders were released, Crytek released version 1.2 of the engine which used some of the capabilities for better graphics. Later the company developed CryEngine version 1.3, which added support for HDR lighting. The engine has been licensed to NCsoft for their MMORPG, Aion: The Tower of Eternity.[22] On March 30, 2006, Ubisoft acquired all intellectual property rights to the Far Cry franchise and a perpetual license to use the Far Cry edition of CryEngine, known as the Dunia Engine.[23]

CryEngine 2

[edit]

CryEngine 2 is used in Crytek's game Crysis, and an updated version in Crysis Warhead, a side story of Crysis. It was first licensed out to French company IMAGTP who specializes in architectural and urban-planning communication. The purpose of licensing the engine was to create a program to allow clients to see exactly what a building or other structure would look like before any actual construction was started. As of March 7, 2011, Simpson Studios has licensed CryEngine 2 out to use on a Massively Multiplayer Virtual World (MMVW) that takes place on a terraformed Mars.[24] On May 11, 2007, Crytek announced that they would be using the engine to create a game based on their new intellectual property. It is also confirmed that it would not be a part of Crysis and in fact may not even be a first-person shooter. On September 17, 2007, Ringling College of Art & Design became the first higher education institution in the world to license CryEngine 2 for educational purposes.

CryEngine 3 (3.0–3.5)

[edit]

Crytek introduced CryEngine 3 at the 2009 Game Developers Conference, held from March 25 to March 27 and demonstrated it on the Xbox 360 and PlayStation 3 consoles. The new engine was being developed for use on Microsoft Windows, PlayStation 3, Xbox 360, and Wii U. As for the PC platform, the engine is said to support development in DirectX 9, 10, and 11.[25][26] As of June 1, 2009, it was announced that Crysis 2 would be developed by Crytek on their brand-new engine.[27] CryEngine 3 was released on October 14, 2009.[28]

Family tree illustrating the history of CryEngine versions

On March 1, 2010, a new tech demo of the engine was released for the i3D 2010 symposium, which demonstrates 'Cascaded Light Propagation Volumes for Real Time Indirect Illumination'.[29] On June 11, 2011, the Australian Defence Force revealed that Navy personnel would train on a virtual landing helicopter dock ship made using the CryEngine 3 software.[30] As of July 1, 2011, the Mod SDK version of CryEngine 3 specifically to create custom maps, mods and content for Crysis 2 is available on Crytek's website. Crytek also released a free-to-use version of the CryEngine for non-commercial game development. It was released as of August 17, 2011 under the name CRYENGINE® Free SDK.[31][32]

Crytek announced on September 9, 2011, that they would be using CryEngine 3 to bring the original Crysis to consoles.[33] It was released for Xbox Live and PlayStation Network on October 4, 2011.[34]

CryEngine (3.6–4)

[edit]

On August 21, 2013, Crytek rebranded CryEngine (starting from version 3.6.0) to simply "CryEngine", and announced that their next CryEngine would not be advertised with a version number. The reason for this decision was the claim that this new engine bears almost no similarity to previous CryEngine versions. However, the development kits available to licensees still use version numbers.[35] The new CryEngine version adds support for Linux[36][37] and consoles such as the PlayStation 4, Xbox One, and Wii U.[38] Subsequent appearances at events have also featured the use of CryEngine on virtual reality systems, at GDC 2015 Crytek brought a demonstration 'Back To Dinosaur Island' to the event to showcase such.[39]

CryEngine V

[edit]

On March 22, 2016, Crytek announced a new version of CryEngine, called CryEngine V. Additionally, a new licensing model was introduced with a "pay what you want" model for usage and access to the source code.[40][41]

On September 21, 2017, CryEngine 5.4 was released,[42] adding the Vulkan API renderer as a beta, substance integration,[43] and other features including new C# templates, asset system updates, and new anti-aliasing techniques.

On March 20, 2018, Crytek changed the licensing from "pay what you want" to a 5% revenue-sharing model.[44]

In April 2022, version 5.7 was released with few new features as the multiple features originally intended to be in 5.7 were scrapped and moved to the next iteration of CryEngine. Version 5.7 included Scaleform 4 support. The developers have stated that this will be the last version of CryEngine V and confirmed they are working on a new iteration of CryEngine.[45] The previous versions prior to 5.7 were deprecated and can not be downloaded.[46][47]

Development

[edit]

The CryEngine software development kit (SDK), originally called Sandbox Editor, is the current version of the level editor used to create levels for CryEngine by Crytek. Tools are also provided within the software to facilitate scripting, animation, and object creation. It has been included with various Crytek games (including, but not limited to, Crysis and Far Cry), and is used extensively for modding purposes. The editing style is that of the sandbox concept, with the emphasis on large terrains and a free style of mission programming. The editor can also construct indoor settings.

As opposed to editors like UnrealEd (Used in Unreal Engine 1, and Unreal Engine 2), which use a "subtractive" editing style that takes away areas from a filled world space, the Sandbox has an "additive" style (like Quake II). Objects are added to an overall empty space. The Sandbox's concentration on potentially huge (in theory, hundreds of square kilometers) terrain, means that it uses an algorithmic form of painting textures and objects onto the landscape. This uses various parameters to define the distribution of textures or types of vegetation. This is intended to save time and make the editing of such large terrains feasible while maintaining the overall "real world" sandbox-free roaming style. This is different from some editing styles that often use "fake backdrops" to give the illusion of large terrains.

In a fashion somewhat comparable to the 3D Renderer Blender, which can be used for game design, the Sandbox editor has the ability, with a single key press, for the editor to jump straight into the current design (WYSIWYP, "What You See Is What You Play" Feature). This is facilitated without loading the game as the game engine is already running within the editor. The "player" view is shown within the 3D portion of the Editor. The Editor also supports all the CryEngine features such as vehicles and physics, scripting, advanced lighting (including real time, moving shadows), Polybump technology, shaders, 3D audio, character inverse kinematics and animation blending, dynamic music, Real Time Soft Particle System and Integrated FX Editor, Deferred Lighting, Normal Maps & Parallax Occlusion Maps, and Advanced Modular AI System.[48]

Overview

Origins and development

GmbH was founded in 1999 by three Turkish-German brothers—Cevat, Avni, and Faruk Yerli—in , , with the initial goal of creating innovative video games that pushed technological boundaries. The company began developing its proprietary game engine, initially known simply as CryEngine, shortly after its inception to support their debut project, the . This from-scratch development emphasized advanced real-time rendering, dynamic lighting, and expansive open-world environments, setting it apart from contemporary engines like or Unreal Engine 1.x. Cevat Yerli, as CEO, envisioned the engine as a tool to deliver unprecedented visual fidelity on PC hardware, drawing inspiration from emerging graphics technologies such as pixel shaders and . The CryEngine made its public debut at the 2004 (GDC), where showcased a technology demonstration highlighting its capabilities for lush tropical islands, AI-driven enemies, and seamless level streaming. Later that year, on March 23, was released for Microsoft Windows, published by under a licensing agreement signed in 2003; the game became a critical and commercial success, selling over 730,000 copies in its first four months and earning praise for its graphical prowess. Initially proprietary to 's projects, the engine was made available for licensing to third-party developers shortly after 's launch, marking an early pivot toward broader industry adoption. However, in 2006, acquired the intellectual property rights, allowing to retain full ownership and control over the engine's future iterations. Building on the success of CryEngine 1, Crytek initiated development of CryEngine 2 in 2005, focusing on enhanced physics simulation via integration with Havok, improved vegetation rendering with technology, and better multi-threading for next-generation hardware. This version powered , released in November 2007, which further solidified the engine's reputation for photorealistic graphics and destructible environments, though it famously strained even high-end PCs of the era. CryEngine 2 was licensed to select developers, including MindArk for , expanding its footprint beyond Crytek's portfolio. In 2009, Crytek announced CryEngine 3 at the Game Developers Conference (GDC), which debuted there and had its SDK fully released in August 2011, introducing cross-platform support for consoles like and , along with unified rendering pipelines and advanced particle effects. This iteration powered (2011) and (2013), while gaining traction with third parties such as for Online. By 2013, Crytek rebranded the engine simply as CRYENGINE (dropping version numbers for major updates starting from 3.6), unifying development branches and emphasizing modularity for VR and multi-platform scalability. The transition to CRYENGINE 5, released in March 2016, represented a significant overhaul with Vulkan API support, forward+ rendering, and cloud-based collaboration tools via the CRYENGINE Launcher. Subsequent updates, such as 5.4 in 2017 adding Substance material integration, 5.7 LTS in April 2022 providing long-term stability with improved animation systems and forward renderer enhancements, and 5.11 in August 2024 for Hunt: Showdown 1896, have kept the engine competitive for AAA titles like Hunt: Showdown 1896.

Historical development

CryEngine 1

CryEngine 1 was developed by , a German game development studio founded in 1999 by Cevat Yerli and his brothers, as a technology demonstration to highlight the potential of Nvidia's GPUs. Initially conceptualized as a tech demo titled X-Isle: Dinosaur Island, it evolved into a full to power the first-person shooter , which created in partnership with publisher for a March 2004 release on Microsoft Windows. The engine's creation marked Crytek's ambition to push PC hardware limits, focusing on seamless integration of advanced graphics and gameplay in expansive tropical island settings. Technically, CryEngine 1 emphasized photorealistic rendering and environmental simulation, featuring PolyBump normal mapping—a technique that combined normal and parallax mapping to simulate intricate surface details like bumps and depth on low-polygon models, reducing geometric complexity while maintaining visual fidelity. It included dynamic global illumination with real-time shadows, volumetric fog effects, and a sophisticated water system capable of simulating realistic waves, reflections, and interactions with objects and characters. The engine also incorporated advanced AI for enemy behaviors, such as tactical pathfinding and reactions to environmental changes, alongside physics-based destructible terrain and vegetation that responded to wind, explosions, and player actions. Motion-captured animations and surround sound further enhanced immersion in open-world environments. Crytek's Sandbox level editor enabled "what you see is what you play" real-time editing, allowing developers to iterate directly within the game world without compilation delays. Following 's commercial success, which sold over 730,000 copies in its first four months and earned critical acclaim for its visuals, Crytek opened CryEngine 1 for licensing to third-party developers, establishing it as a commercial product. In March 2006, acquired the rights to the franchise along with a perpetual to the Far Cry-specific edition of the engine, enabling continued use and modifications for sequels while Crytek retained ownership of the core technology to evolve into later iterations. This version of the engine influenced early 2000s PC gaming by setting standards for graphical realism and open-ended FPS design, though it remained PC-exclusive and was not ported to consoles.

CryEngine 2

CryEngine 2 was developed by GmbH as the successor to CryEngine 1, with primary focus on powering the 2007 Crysis. Development began following the success of in 2004, aiming to push PC hardware limits through enhanced realism in visuals, physics, and environmental interactions; the engine was announced alongside Crysis in January 2006 by and publisher .

Community efforts have continued, including the release of the CryEngine Community Edition in October 2025, a free patch adding new features to the 5.7 base.

Core features

Graphics and rendering

CryEngine's graphics and rendering system is built around a hybrid deferred and forward shading that supports high-fidelity visuals through a linear (HDR) workflow. For instance, water surfaces are forward shaded while water caustics, such as foam, are handled via deferred shading for performance optimization. This processes , , and effects in stages to optimize while enabling complex scene rendering. It leverages modern APIs such as 12 for improved multi-threading and resource management, allowing efficient handling of large-scale environments. At the core of the shading model is , introduced in CryEngine 3.6 and refined in subsequent versions. PBS adheres to physical principles for material representation using a Specular/Gloss workflow, employing properties like , specular color (reflectance), and gloss (smoothness) to simulate realistic light interactions without empirical tweaks. This approach ensures consistent results across lighting conditions and supports for enhanced realism. Materials are authored with physically accurate parameters, promoting and based on microfacet theory. Lighting in CryEngine emphasizes dynamic and global illumination techniques. The engine supports fully dynamic area lights and real-time via Sparse Voxel Octree Global Illumination (SVOGI), Crytek's SVOTI/SVOGI implementation of which uses cone tracing as part of its ray-tracing method that captures indirect bounces from static and dynamic objects at large scales. Crytek often refers to it as SVOTI (Sparse Voxel Octree Total Illumination), a broader term for the total illumination system including global illumination features. SVOGI builds a to propagate light efficiently, providing and color bleeding without precomputation. For shadows, traditional cascaded shadow maps are augmented by ray-traced shadows, which deliver physically accurate penumbras and contact hardening by tracing rays against scene geometry. Advanced rendering effects include for detailed displacement, real-time dynamic caustics that simulate through surfaces, and 3D HDR lens flares for volumetric scattering. Post-processing encompasses high-quality effects like bloom, depth-of-field, and within the HDR pipeline. is handled primarily through Temporal Supersampling (TSAA), which accumulates samples over frames using slight variations to reduce artifacts while maintaining temporal stability. Later updates to the engine, such as the upgrade to version 5.11 for Hunt: Showdown released on August 15, 2024, have integrated upscaling technologies such as FidelityFX Super Resolution 2 (FSR 2) for performance boosts on lower-end hardware. Ray tracing capabilities, added in later updates, extend to reflections and refractions, as demonstrated in the benchmark, which achieves real-time mesh-traced effects on compatible hardware. These features collectively enable photorealistic rendering, with the pipeline designed for scalability across platforms.

Sandbox editor and tools

The Sandbox editor is the central within CryEngine, serving as an all-inclusive content authoring tool that enables real-time, what-you-see-is-what-you-get () editing for game world development and in-game preview. It forms the heart of CryEngine's game development pipeline, allowing users to create levels, manipulate assets, and integrate physics simulations directly within a unified interface. This modular design supports , with tools that facilitate both high-level world-building and fine-grained adjustments, eliminating the need for separate applications or lengthy compilation times. At its core, the Sandbox provides intuitive level design capabilities, including terrain editing for sculpting landscapes, applying textures, and generating vegetation through procedural tools. management is handled via a robust set of operations: developers can select, move, rotate, and scale objects using transform tools, with snapping and alignment features ensuring precise positioning. Additional controls include grouping for organized hierarchies, linking for relational dependencies, freezing to lock positions, and hiding to declutter the during complex scenes. These features, customizable via keyboard shortcuts and options, streamline workflows for placing assets like characters, vehicles, and environmental props. Regarding asset import, CryEngine utilizes the official FBX pipeline, where source FBX files are retained in the game folder, and the engine compiles them to .cgf format. Both the source and compiled files are visible in the Asset Browser. Alternatives to building a custom Assimp-based importer include pre-processing assets in Blender using Assimp addons to export clean FBX files for standard import. For the glTF format, there is no native support, but it can be accommodated by developing a custom plugin, which may require several weeks. For animation and sequencing, the Trackview cinematic editor allows keyframing of cameras, entities, and effects to build cutscenes and dynamic events, integrating seamlessly with the real-time preview system. The editor also incorporates specialized tools such as the Audio Controls Editor (ACE), which is not a standalone replacement for audio middleware like FMOD or Wwise but instead abstracts over them. It works by a system of audio triggers and objects, where audio objects are constructed from data such as position and audio occlusion quality. Triggers are then executed upon objects, which map to middleware (Wwise, FMOD, or SDL) sound events. In this way, the game code describes events, and the ACE maps them to sound events. In CRYENGINE 5.x, entity systems leverage a component-based architecture, where modular components can be added to empty entities or helpers for behaviors like physics or AI, enhancing extensibility through plugins and Qt-based customization. Overall, these tools emphasize efficiency, with real-time rendering ensuring immediate visual feedback on changes like and materials.

Simulation systems

CryEngine's simulation systems encompass a suite of integrated technologies designed to model realistic interactions in game worlds, including physics, (AI), and environmental dynamics. These systems enable developers to create immersive experiences with believable object behaviors, character decision-making, and natural phenomena, all processed in real-time across multiple platforms. The engine's simulations prioritize and performance, supporting complex scenes without compromising frame rates, and are built on multi-threaded architectures for efficient computation. As of 2025, core simulation features are maintained through community-driven patches to the last official release (CRYENGINE 5.7, 2022).

Physics Simulation

The physics system in CryEngine provides a comprehensive, out-of-the-box solution for handling , soft body interactions, and environmental effects in real-time complex scenes. It supports object-based entities with arbitrary meshes attached to dynamic objects, allowing for detailed and response. Articulated structures can be simulated through a dedicated mode that manages joints and constraints, facilitating realistic machinery or creature movements. Destruction mechanics are implemented via pre-broken parts connected by tension-based joints, complemented by dynamic subtraction for runtime fracturing that suits gameplay needs, such as explosive impacts or structural collapses. Vegetation simulation integrates touch bending, where foliage realistically deforms under interactions with players, objects, wind, or AI entities, enhancing environmental immersion without requiring manual animation. Water and buoyancy simulations feature precise calculations for floating objects in water, air, or custom volumes like rivers and oceans, including wave interactions and self-adjusting water distribution around vessel geometries for authentic naval physics. Advanced rope physics utilize a specialized tool for creating ropes, chains, or cables with repeating segments, supporting various collision modes and attachment points to simulate dangling or tensioned elements dynamically. Vehicle simulations build on these foundations, incorporating soft body elements for deformable components like tires or chassis, enabling high-fidelity driving mechanics.

AI Simulation

CryEngine's AI system employs modular sensory modules for hearing, sight, and other perceptions to drive character behaviors, allowing non-player characters (NPCs) to react intelligently to their environment. It includes for defining hierarchical decision-making logic, enabling complex actions like patrolling, combat, or exploration through visual scripting in the Behavior Tree Editor. Navigation is handled via navigation meshes that generate paths for AI movement, supporting dynamic obstacles and multi-layered terrains for accurate in large-scale worlds. A key component is the Universal Query System (UQS), which performs spatial queries to identify, rank, and filter entities in 3D space, powering AI decision processes such as threat assessment or resource allocation. UQS is currently in beta and intended to supersede the more stable Tactical Point System (TPS), which has been used since Crysis for AI spatial queries. UQS integrates with legacy systems like the Goal-Oriented Action Planning (GOAP) for tactical behaviors, while newer implementations emphasize modularity for easier customization. Smart objects enhance AI interactions by defining affordances, such as climbable ledges or usable doors, simulating contextual awareness. Animation simulation ties into AI through advanced blending and state machines, ensuring seamless transitions between locomotion, idle poses, and reactive motions to maintain visual realism during behavioral simulations. These simulation systems are interconnected; for instance, physics influences AI pathing around destructible environments, and sensory inputs from simulations inform behavioral responses, creating cohesive world interactions. Updates in CRYENGINE 5.7 (2022) refined simulation fidelity.
