PromptMotion Lite - AI Animation Generator

No payments. No API setup. No subscription fees. No per-generation fees. No leaving Unity.

This asset is the free Lite edition of the PromptMotion framework.

The Lite edition: one-click Humanoid animations from text prompts — directly inside the Unity Editor, providing the perfect free tier to test the AI pipeline on your own characters before upgrading.

This asset uses NVIDIA's Kimodo model to generate the animations.

Type what you want your character to do. Click Generate. Usually in under a minute, a Humanoid-retargeted FBX animation is downloaded, automatically imported, previewed in the editor, and applied to your character with one click. Get instant AI-generated clips without ever leaving Unity.

💎 LITE vs STANDARD vs PRO

Ready to build out a full game or unlock professional animation authoring? Choose the tier that fits your production scale:

• PromptMotion Lite (This Version): Free forever. Includes 5 lifetime generations and the core text-to-animation engine. Perfect for testing the technical integration and performance with your custom rigs.
• PromptMotion Standard: Paid. Upgrades you to 50 generations / month and unlocks the Bundled Animation Library — a Mixamo-style browser of hand-picked starter clips covering locomotion, combat, idles, and gestures that work 100% offline.
• PromptMotion Pro: Paid. The ultimate animation suite. Grants 150 generations / month plus the complete Pro Toolset (Clip Cleanup, Mecanim Blend Tree Wizard, Batch Generation, and Timeline Sequencer) to turn raw AI clips into production-ready, shippable animations inside Unity.

💡 WHY PROMPTMOTION LITE

✅ 5 LIFETIME GENERATIONS — Test the generation engine completely for free. See exactly how the AI handles your prompts and custom character rigs before committing.

✅ STREAMLINED WORKFLOW — Zero-friction AI generation. Go from a text prompt to a previewable, ready-to-wire animation asset in seconds, completely contained in one editor window.

✅ CACHED PROMPTS ARE FREE — Re-generating or downloading previously cached prompts doesn't count against your generation limit.

✅ HUMANOID-RETARGETED OUTPUT — Every animation is delivered as an FBX with Unity Humanoid bone mapping. Plays on any Humanoid character — Mixamo, Synty, Ready Player Me, your own custom rig — out of the box.

✅ FULLY AUTOMATIC IMPORT — Avatar configuration, animation extraction, and clip application all happen automatically after generation. Zero manual steps.

✅ EMBEDDED PREVIEW — Generated clips play on your character in a viewport inside the editor window. Scrub, loop, change speed, see the result before applying.

✅ ZERO RUNTIME OVERHEAD — All scripts are Editor-only. Your build size and runtime performance are completely unaffected.

✅ EASY ACTIVATION — Enter your email code to activate the tool window and start generating right away.

🎁 INCLUDED ALLOWANCE

5 lifetime generations are issued entirely for free with this Lite edition. It is purpose-built to let you verify the rig compatibility, test out your ideas, and experience the workflow firsthand.

🎬 WHAT YOU CAN GENERATE

• Locomotion — walks, runs, sprints, jumps, climbs, crawls
• Idles & poses — standing, sitting, leaning, crouching, sleeping
• Combat — punches, kicks, sword swings, dodges, blocks
• Gestures — waves, bows, pointing, applause, shrugs
• Reactions — surprised, hurt, knocked back, falling
• Sports & athletics — backflips, cartwheels, dancing, yoga
• Emotional acting — sad, angry, excited, exhausted body language
• Daily activities — sitting down, picking up objects, drinking, throwing
• And much more — any body motion you can describe

🚀 HOW IT WORKS

1. Enter your activation email code to unlock the interface.
2. Drag a Humanoid character into the Character slot (any Mixamo, Synty, RPM, or custom Humanoid rig works).
3. Type your motion prompt, e.g. "a person waves with their right hand."
4. Click GENERATE.
5. The cloud AI generates motion data, retargets it to Unity Humanoid, and returns an FBX.
6. The FBX is downloaded to Assets/PromptMotion/Generated/, imported with correct rig settings, and previewed inside the editor window with full transport controls (play/pause/scrub/speed/loop).
7. Click APPLY TO CHARACTER to wire the clip into your character's AnimatorController.
