Version 1.3

April 16th, 2019 - Unreal Engine 4.20 - 4.22

New Features:

Change Tick Rate of State Machine

  • State Machines now support a variable delay in seconds between ticks.


  • Added explicit Tick override option for ActorComponents.
  • Added/Removed some EditConditions around tick properties to better display when one option requires another.
  • Adding or changing a State Machine reference will default the path to the current Blueprint's folder.
  • Initializing State Machines when using nested references improved.

Bug Fixes:

  • Duplicating a top level K2 State Machine node will correctly rename it when the name is already in use.

Version 1.2

April 2nd, 2019 - Unreal Engine 4.20 - 4.22

New Features:

Add Reference to State Machine

  • Other State Machine blueprints can now be directly referenced within a State Machine graph. This allows a single State Machine to be reused multiple times.
  • The context of the super State Machine will be passed into the reference automatically.
  • The reference will inherit the super State Machine's replication settings.

Convert State Machine to Reference

  • Convert an existing State Machine in-place to a reference.
  • This will also look for any existing variables that are referenced and recreate them in the new blueprint. Any additional event graph logic or custom functions won't be copied.

Bug Fixes:

  • Blueprint Helper Nodes (Such as 'Time in State') can now be copied and pasted into supporting graphs.
  • Removed EditAnywhere from some properties which weren't intended to be modified manually.

Version 1.1

February 21st, 2019 - Unreal Engine 4.19 - 4.21

New Features:

Collapse Nodes to State Machines

  • Selected state nodes can be collapsed to a nested state machine while preserving transitions.


  • Can add comments to state machine graphs.

Bug Fixes:

  • Multiple instances of a state machine can be debugged properly now.
  • Fixed crash when a nested state machine was removed while opened in the editor.
  • Added work around for engine level crash when undoing the creation of a graph for the second time while the graph is open in the editor.
You can’t perform that action at this time.
