CRYENGINE 5.5 Preview 6 is available now through CRYENGINE launcher and GitHub! As you know, work never stops on the development of the engine, and today’s update pushes things forward with a dozen improvements and some important middleware updates. We couldn’t have put this update together without the help of our community, so as ever, we’d like to thank everyone for all your feedback and suggestions. Keep it coming!

Accessing the 5.5.0 Preview 6 Release

CRYENGINE Preview versions are available through the CRYENGINE Launcher.

For more information on getting started with the CRYENGINE source code from GitHub please visit our technical documentation on Building the Engine from Source Code.

Code Interface Changes

For more information, see the Important CRYENGINE 5.5 Data and Code Changes article.

If you are upgrading from CRYENGINE 5.4, please read this topic: Migrating from CRYENGINE 5.4 to CRYENGINE 5.5.

Known Issues

All Known Issues are Work in Progress. If you encounter those or similar problems please let us know, but be aware that we are already looking into it.

  • CRASH: VS 2017 v15.8 causes compile issues resulting in CRYENGINE crashing. Users should therefore ensure that they have an earlier version of Visual Studio installed on their PC.
  • TWEAKED: Reflections are broken if a material is attached to an object. Can be tweaked with "r_ssreflsamples" and "r_ssrefldistance".
  • CRASH: Vulkan crashes after level load.
  • CRASH: Sandbox Editor crashes if a particle effect is placed in the level and is opened in the Particle Editor.
  • DESIGNER TOOL: Designer objects may be invisible after levelload/chainload. Workaround: Enable, then disable e_permanentRenderObjects 0/1.
  • C#: Using the CRYENGINE C# extension for Visual Studio 2017 to start the GameLauncher, Sandbox Editor or Server can cause an error when used in Visual Studio 2017 v15.7. More information and a fix for this issue can be found here.
  • ENTITY: Light Projector does not cast any shadows.
  • ENTITY: Using an entity/component as movement, rotation pivot/joint in Trackview does not play the animation in-game and or in pure game.

Release Notes


Middleware Updates

  • Updated to Wwise SDK 2018.1.0 (NOTE: If using CRYENGINE 5.5.0 Preview 6 (and future versions of CRYENGINE), then users MUST update their Wwise version to at least version 2018.1.0 or later. NOTE: Earlier versions of CRYENGINE i.e. up to and including CRYENGINE 5.5.0 Preview 5 MUST use a Wwise version that is prior to Wwise 2018.1.0.
  • Updated to Fmod Studio 1.10.07.


Action General

  • Fixed: Container Entities do not output correct data.

Graphics and Rendering

Renderer General

  • Fixed: GetDebugName platform ifdef - fixed compilation for Durango.
  • Fixed: Scaleform memory leak.
  • Fixed: Pipeline State Object (PSO) pool growing unbounded.
  • Tweaked: Allow recursive release of rendernodes.

Additional Fixes

  • Fixed: (Entity System) Crash after jumping into any level and trying to exit.
  • Fixed: (Entity System) Unremovable entities were not hidden when they were removed.
  • Fixed: (Renderer) Missing information in water volume reflections.
  • Fixed: (Sandbox Editor) Opening a level through the Asset Browser will set the wrong level path. When saving a level, legacy code in mission, terrain, vegetation etc. will fail to resolve the path.
  • Fixed: (CryDefaultEntities) Assertion and crash in the MannequinObject after deletion. The MannequinObject was changed to an IEntityComponent but still behaved like a GameObject on shutdown.
  • Tweaked: (Animation) Vcloth parameter names have been changed in order to clarify that constraints are enforced and propagated locally between nearest neighbors only. NOTE: Users will need to override defaults and set the values for the new Nearest Neighbor Distance Constraints (NNDC) parameters.
  • Tweaked: (Character Tool) Checkbox for NNDC now switches to disabled after re-loading.
  • Tweaked: (Water Volumes) Added more parameters.
  • Tweaked: (Water Volumes) Improved fade-out parameters to suppress glaring step-artifacts between missing and non-missing Screen Space Reflection(s) (SSR) information.
  • Tweaked: (Sandbox) Don't handle mouse events in Level Editor Viewport if no level is loaded.
  • Tweaked: (Renderer) Move GPU particles update into Update() rather than Execute().

Reminder: This is an experimental release and features are subject to changes, bugs, and gremlins, as you’d expect with a beta production. Please back up your projects before working with any of our latest builds to make sure your core project is safe. If you find an issue please reach out to us via the collective CRYENGINE 5.5 Build Feedback Thread on the official forum or report issues via GitHub Issue Reporter.

How to report Crashes: In case of engine crashes, please use the Crash Reporter in the launcher when it pops up and don't forget to attach all reports! We hope you enjoy the build and we look forward to seeing what you can do with it. For guides on how to best submit an issue or if you need to contact customer support, please review the 'How to contact CRYENGINE Official Support Channels' landing thread on the forum.

    @manran RTX is not yet playable(Only with 3x RTX 2080ti for 3900 dollars), in 5-8 years it is optimized and playable, and until then Crytek has developed something of its own. (Sorry for my English)

    @deepsky @xiangqian Unreal and Unity are years behind, Cryengine technology is much better optimized and advanced. 1000 players simultaneously in the Cryengine, Unity and Unreal only delivers a slideshow with 10 fps (Sorry for my English)

  • deepsky

    Here are two words that should scare this hell out of Crytek.... UNREAL and UNITY. The old days are gone.. INNOVATE, EVOLVE OR get left behind.

  • xiangqian

    This is a special moment. If you don't catch up, you will be eliminated by unity3d and unreal. The people who use it will only be less and less. In the end, they will only circulate internally, and no one will use it. Leaders should Look at the world, listen to the voice of the developers, everyone does not want to say anything now, there is no passion
