Skeletal Mesh Animation System

System for deforming skeletal meshes based on keyframed animation data and morph targets.


The animation system in Unreal Engine 4 (UE4) is comprised of several Animation Tools and Editors which mixes skeletal-based deformation of meshes with morph-based vertex deformation to allow for complex animation. This system can be used to make basic player movement appear much more realistic by playing and blending between canned Animation Sequences, create customized special moves such as scaling ledges and walls using Anim Montages, apply damage effects or facial expressions through Morph Targets, directly control the transformations of bones using Skeletal Controls, or create logic based State Machines that determine which animation a character should use in a given situation.

Welcome to the new Unreal Engine 4 Documentation site!

We're working on lots of new features including a feedback system so you can tell us how we are doing. It's not quite ready for use in the wild yet, so head over to the Documentation Feedback forum to tell us about this page or call out any issues you are encountering in the meantime.

We'll be sure to let you know when the new system is up and running.
