# processAndCreateAnimation(retargeting:operations:name:) Processes skeletal animation with the specified retargeting and operations. ``` func processAndCreateAnimation(retargeting config: RetargetingConfiguration, operations: [SampledAnimation.SkeletalAnimationOperation] = [], name: String = "") throws -> any AnimationDefinition ``` ## Parameters `config` The skeletal retargeting configuration to use. `operations` Operations to perform on the animation. If empty, only retargeting is performed. `name` Name for the processed animation. ## Return Value An [`AnimationDefinition`](/documentation/RealityKit/AnimationDefinition) containing the processed animation. If root motion extraction is performed, returns an [`AnimationGroup`](/documentation/RealityKit/AnimationGroup) containing both the skeletal animation (`SampledAnimation`) and extracted root motion (`SampledAnimation`). Otherwise returns a `SampledAnimation`. ## Discussion Retargets the instance animation using the provided retargeting configuration and applies a series of skeletal animation processing operations to create a new animation definition. The function executes operations in the order specified. > Throws: An error if validation fails. All errors provide descriptive messages via their > `localizedDescription` property. Common validation failures include: > > - Duplicate operation types in a single call (e.g., two ``doc://com.apple.RealityKit/documentation/RealityKit/SampledAnimation/SkeletalAnimationOperation/extractRootMotion(jointName:options:lockPosition:)`` operations). > - Both ``doc://com.apple.RealityKit/documentation/RealityKit/SampledAnimation/SkeletalAnimationOperation/extractRootMotion(jointName:options:lockPosition:)`` and ``doc://com.apple.RealityKit/documentation/RealityKit/SampledAnimation/SkeletalAnimationOperation/removeAnimation(for:)`` operations in the same call. > - Operations requiring a skeleton when skeleton parameter is nil. > - Joint name does not exist in the skeleton for root motion extraction or removal. > - Base animation has a different sample rate than the source animation for ``doc://com.apple.RealityKit/documentation/RealityKit/SampledAnimation/SkeletalAnimationOperation/convertToAdditive(baseAnimation:)``. --- Copyright © 2026 Apple Inc.
