Pose Search (Motion Matching)

Blueprint AI builds the Motion Matching asset family: the schema that defines what a pose is sampled on, the database that indexes animations against it, interaction assets for multi-character motion, and normalization sets that share cost normalization across databases.

Note

Conditional on the engine’s PoseSearch plugin. Schemas are bound to a skeleton; databases are bound to a schema, so author them in that order.

Schemas

Create a Pose Search schema called PSS_Locomotion for the SK_Mannequin skeleton in /Game/MotionMatching Set its sample rate and indexing flags on PSS_Locomotion Add a second roled skeleton to PSS_Interaction for a two-character interaction Describe the schema PSS_Locomotion

Databases

Create a Pose Search database called PSD_Locomotion bound to PSS_Locomotion Set the search mode and KD-tree settings on PSD_Locomotion from this JSON Describe the database PSD_Locomotion to see its cost biases, search mode, and tags

Interaction assets

Create a Pose Search interaction asset called PSI_Vault in /Game/MotionMatching Append an item that plays AM_Vault for the Climber role Set its WarpingBankingWeight to 0.5

Normalization sets

Create a normalization set called PSN_AllLocomotion Add PSD_Locomotion and PSD_Strafe to PSN_AllLocomotion Describe the normalization set PSN_AllLocomotion

Tip

Every database, schema, and interaction asset exposes a dotted-path property getter and setter, so any field the Motion Matching editors show can be read or tuned by name.
