MotionSmith AI Animation Studio

MotionSmith AI is an AI-assisted 3D character animation authoring plugin designed to bring motion generation, continuation, editing and retargeting directly into the Unreal Editor.

Describe a physical action in natural language, generate character motion, review it on the MotionSmith timeline, extend the performance with additional prompt segments, import existing Unreal AnimationSequences and continue from their motion tail, then retarget the result to supported character workflows and output a standard Unreal AnimationSequence.

Core Features

• Text-to-3D Motion Generation
  Generate character motion from focused natural-language action prompts.

• Multi-Segment Animation Timeline
  Build longer performances beat by beat using Add Segment while preserving the previously approved animation.

• Import + Continue
  Import an existing Unreal AnimationSequence, adjust it with MotionSmith's Transform tools if needed, and generate new motion continuing from the imported animation tail.

• Motion Editing Tools
  Refine generated or imported motion with transform, pose and authoring controls directly inside MotionSmith.

• Unreal Auto Retargeting Workflow

  
  Preconfigured workflows are included for:

  • UE5 Manny / Quinn

  • MetaHuman

  • Character Creator

  • Mixamo

• AnimationSequence Output

  
  Create standard Unreal AnimationSequence assets ready for use with:

  • Sequencer

  • Animation Montages

  • Animation Blueprints

  • Standard Unreal animation workflows

• Prop References
  Import props into the MotionSmith authoring scene as spatial references while directing and adjusting character animation.

• Local AI Inference
  Motion generation runs locally on supported NVIDIA CUDA hardware after the required MotionSmith Runtime and models are installed.
  

Integrated Setup

MotionSmith includes a guided first-time setup workflow inside Unreal Editor.

No manual Python, PyTorch or NVIDIA Kimodo installation is required.

The MotionSmith setup page provides:

• MotionSmith Runtime installation

• Environment validation

• Meta Llama 3 8B Instruct setup

• Backend lifecycle management

• Diagnostics / Pre-Flight checks

Opening MotionSmith automatically starts the local backend. Closing MotionSmith automatically stops it. A Restart Backend action is available for recovery when required.

Requirements

• Unreal Engine 5.8

• Windows 64-bit

• CUDA-capable NVIDIA GPU

• Internet connection for first-time Runtime/model setup

• Hugging Face account

• Access to the official Meta Llama 3 8B Instruct repository

• Sufficient local storage for the Runtime and AI model files

Meta Llama 3 model weights are not redistributed with MotionSmith. During setup, the user supplies their own Hugging Face access and MotionSmith handles the supported download and installation workflow.

Third-Party Technology

MotionSmith AI builds upon the open-source NVIDIA Kimodo motion generation project.

MotionSmith AI is an independent product and is not affiliated with or endorsed by NVIDIA.

Meta Llama 3 is provided under Meta's applicable license and access terms.
