You can write your topic however you want, but you need to answer these questions:
What do you want to achieve? animation should play attaching with the ground
What is the issue? my horse sitting animation is well played in animation editor but whenever i played it in game it floats automatically
What solutions have you tried so far? I tried adjusting Hip Height of the humanoid,
HumanoidRootPart.Velocity and adjust pivot points of the horse and also changed the horse.
Uhhhh… can u put the animation lower? idk. If it insists on floating, put it in the ground.
try remaking the whole animation. Is it just a pose? or like an animation sequence of the horse laying down? Is it a full-body animation? (do you need a humanoid? It looks like a custom rig…)
Does the horse have a RootPart? Because if so you must have animated the RootPart with the rest of the animation. Also you can just move the horse down during this animation.
