Type a prompt, get a skeletal animation: generated on your own GPU, retargeted to your character and saved as an Animation Sequence. No cloud, no subscription, no API keys.

Text To Anim brings text-to-motion generation into the Unreal Editor, running entirely on your machine. Describe a movement in plain English — "a person walks forward, then turns left and sits down" — and get a clean skeletal animation in seconds, previewed live on your character.

Highlights

• Local and private: the model (NVIDIA Kimodo) runs on your NVIDIA GPU. After the one-time model download, nothing leaves your PC. No account, no credits, no per-generation cost.

• Multi-prompt Clips with generated transitions: chain segments on a timeline ("walk" → "turn" → "sit"); the model generates the transitions between them. Takes per segment, regenerate only what changed.

• Direction control: set a heading or a point to reach on the floor for each segment, right in the viewport.

• Seamless Loops: one prompt, automatic cycle detection and blending, In place or Root motion — ready for Blend Spaces and locomotion.

• Automatic retargeting with Unreal's IK Rig and IK Retargeter: UE5 Manny/Quinn, UE4 Mannequin, MetaHuman bodies, Mixamo and other humanoid skeletons Unreal recognizes. Live preview on your character. Uses Unreal's built-in IK Rig plugin, enabled automatically together with Text To Anim.

• Real assets: Animation Sequences with Root motion, In place or Animated root; update them in place after you pick another take.

• Safe by design: the model runs in a separate process, so a GPU error never closes your editor.

• Editor-only: nothing ships in your game.

Requirements

• Unreal Engine 5.6, 5.7 or 5.8, Windows 64-bit

• NVIDIA GPU, RTX 20 series or newer, with a recent driver

• AMD and Intel GPUs are not supported in this version: support for them (via Vulkan) is in development, with no release date yet

• 16 GB RAM (32 GB recommended), ~10 GB free disk space

• Unreal's built-in IK Rig plugin (enabled automatically)

First-use model download

The AI model weights (~9.3 GB) are not included. They are downloaded directly from their official Hugging Face repositories (LocalAI-io/Kimodo-SOMA-RP-v1.1-GGML and LocalAI-io/Llama-3-Kimodo-GGML): by the plugin itself when you click "Download Models" in its panel (no external program or script), or by hand following texttoanim.altercode.dev/getting-started/download-models. Verified with SHA-256. By downloading them you accept the NVIDIA Open Model License (Kimodo) and the Meta Llama 3 Community License (text encoder). Internet is needed only for this download.
