Sorry for the delay, Yes I got it to work in The Game Animation Samples version 5.4
The Game Animation Samples is different in every version so for right now use 5.4 with the Horse Starter Kit (See Video)
First Migrate the HorseStarterKit into a new build of the GameAnimationSamples (Unreal v 5.4)
Then follow along with the video. In this example I’m using the Quinn character.
first open the CBP_SandboxCharacter and in the Class Settings re-parent to “BP_ThirdPersonCharacter_Rider_Parent”
Next in the HorseStarterKit Blueprint folder open the Quinn_Rider blueprint- then in the Class Settings you will be changing the Parent here as well- re-parent to “CBP_SandboxCharacter_Quinn”.
Then in both the parent Horse and Parent Rider blueprints you will want to Set the visibility nodes to Propagate to children (see where in the video)
now you need to add a few Horse ground targets to the level and drag in a Horse. Finally you will want to add a Nav mesh volume to the level so the Horse can find its way around when unmounted.
Now try testing, Also remember you can call the Horse to you using the “F” key, and Mount the Horse using the “E” key
I do eventually plan on making this the default for the HorseStarterKit but the GameAnimationSamples keep changing every version so I will probably wait until it is more consistent.
Hope that was helpful getting you up and running. I will look into getting this working in other versions but for right now this is how to get the HorseStarterKit running with the GameAnimationSamples in version 5.4.
