A deep dive into motion editing with the Unreal Engine Sequencer Animation Mixer. This video covers building an Anim Mixer setup from scratch and configuring Root Motion Settings — including Space, Source, Mode, Loop Mode, and Bone Match — to precisely control how animation data drives character movement. Practical examples include layering library animations with raw mocap data, using Crossfade Transitions between clips, and debugging character trajectory in the viewport.
