Known Issues

  • RENDERER: Reflections are broken if a material is attached to a object. Can be tweaked with "r_ssreflsamples" and "r_ssrefldistance". 
  • CRASH: Game will crash on startup with Vulkan. 
  • CRASH: Legacy PFX can cause a crash shortly after being added to a level 
  • PARTICLE EDITOR: Changes to a particle effect in the new Particle Editor are not directly applied to the Particle Effect instances in the level (currently a level reload is necessary). 
  • CRASH: Occasionally the editor crashes if a particle effect is placed in the level and is opened in Particle Editor. 
  • DESIGNER TOOL: 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 the latest version of Visual Studio 2017. More information and a fix for this issue can be found  here.
  • ENTITIES: Light Projector does not cast any shadows.
  • ENTITIES: Using an entity/component as movement, rotation pivot/joint in Trackview does not play the animation in-game and or in pure game.


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().
