  • Spline based routes
  • First & Third person character examples + AI
  • Compatible with ALS (Advanced Locomotion System v4)
  • Simple IK hand placement setup (hands adapt to the ground height)
  • Examples for all
  • Ground detection for first person arms
  • Option to rotate by ground detection or spline point rotation
  • Visual debugging options
  • Double or single direction routes
  • Per instance exit limit distance (distance to the end for the player to "take off", for both sides independently)
  • Per instance exit location (Where the player will move automatically when exiting)
  • Auto interaction when approaching the entrance/exit
  • Forward and backwards movement (backwards movement can be disabled per route)
  • Configurable speed (independent for moving forward/backward)
  • Camera shake on movement (is not an actual camera shake but rotation applied based on bone rotation, so you can control it from within the animation)
  • Arm/Body animations can't be stopped half the way (animation always ensures both hands are on ground)
  • Arms/Body are orientated to the direction of the spline, letting you create routes of any kind
  • Camera limits


For component based system, use Unreal Engine 4.24+

For the legacy system, use the Unreal Engine versions 4.22 or 4.23

NOTE: Animations are not production ready, they might fit for your game, but you probably want to replace them by your own, with better rigging. There is a tutorial on how to integrate your own animations.

Important/Additional Notes:

  • There are some situations with non desirable results, like too pronunced going downs or really sharp corners in the route (the arms don't look realistic at all in those cases) but you should be able to fix it to fit your needs, for example improving the IK system that already comes with the pack.
