In Unreal 5.8, motion matching is the Pose Search plugin's Motion Matching node: a Schema defines query channels and links to Database assets of animations, replacing hand-built transitions, and locomotion clips must carry root motion with the Root Motion property enabled. The Unity Kinematica (preview) and Learned Motion Matching memory/training claims remain producer-verified. Curator qualifications: Docs read 2026-10-22; no engine setup tested. Kinematica pages and Holden et al. 2020 paper not re-read. Limitations: Docs read 2026-10-22; no engine setup tested. Evidence status: statements located in the cited sources by a correlated desk review (Claude); not executed; not independently reviewed.
