Getting Started with Mootion: Create 3D Animations from Text
Learn how to use Mootion's AI interface to convert natural language descriptions into professional 3D character animations without manual keyframing.

1
Access the Platform and Select Your Model
Navigate to the Mootion website and log in to your account. Once on the dashboard, you will see the main generation interface. The first critical decision is selecting your base 3D model. Mootion provides a library of pre-rigged humanoid characters. For this tutorial, select a standard humanoid model (e.g., 'Male 1' or 'Female 1') to ensure compatibility with common animation rigs. These models are already set up with skeletal structures that the AI understands, allowing it to map text descriptions directly to bone movements. If you are an advanced user with custom rigged models, you may upload your own, but for a beginner workflow, using the provided assets ensures the highest fidelity in motion generation without requiring external rigging software like Blender or Maya for setup.
Pro Tip
Start with the default humanoid models to understand the motion quality before attempting to upload custom rigs, which may require specific bone naming conventions.

Crafting Effective Text Prompts
In the text input field, describe the action you want the character to perform. Mootion relies on natural language processing, so clarity is key. Avoid vague terms like 'move around.' Instead, use specific action verbs and contextual details. For example, type: 'A man picks up a box from the floor, holds it for two seconds, and places it on a table.' You can also add stylistic modifiers such as 'slowly,' 'energetically,' or 'casually' to influence the timing and weight of the animation. The AI interprets these nuances to adjust the velocity and easing of the movement. If you are unsure about specific phrasing, try breaking complex actions into simpler, sequential sentences. The system will attempt to blend these actions into a coherent motion sequence. Remember that the AI does not understand abstract concepts like 'sadness' unless you describe the physical manifestation of that emotion, such as 'slouches and looks down slowly.'
Pro Tip
Use precise verbs (e.g., 'sprint' vs. 'run') and include temporal cues (e.g., 'pause for 1 second') to gain better control over the timing of the animation.

Configuring Generation Parameters
Before generating, review the advanced settings panel. Here you can adjust the duration of the animation loop and the resolution of the output. For most use cases, the default settings are sufficient, but you may want to toggle 'Looping' if you intend to use the animation as an idle state or a repetitive action in a game engine. Additionally, check the 'Smoothing' option. Enabling higher smoothing levels can reduce jitteriness in the AI-generated motion, which is particularly useful for subtle movements like breathing or idle standing. If you are generating a dynamic action like a jump or a fight sequence, lower smoothing settings might preserve the sharpness of the impact. Take a moment to preview the prompt length; longer prompts may take slightly more time to process but offer greater specificity. Ensure that your description matches the physical capabilities of the selected model to avoid unnatural distortions or clipping issues during generation.
Pro Tip
For looping animations, ensure the start and end poses are similar to prevent jarring transitions when the animation repeats in your final project.

Generating and Reviewing the Animation
Click the 'Generate' button to initiate the AI processing. Mootion will analyze your text and map the actions to the character's skeleton. This process typically takes a few seconds to a minute, depending on the complexity of the prompt and server load. Once complete, the 3D viewport will display the animated character. Carefully review the motion from multiple angles. Look for any unnatural joint rotations, foot sliding, or clipping through the ground plane. The preview window allows you to scrub through the timeline to check the timing of specific actions. If the animation does not match your intent, do not immediately regenerate. Instead, edit your text prompt to refine the description. For instance, if the character's arm looks stiff, add 'relaxed arm swing' to your prompt. Iterate until the motion feels natural and accurate to your vision. This iterative process is the core workflow of AI-assisted animation, allowing for rapid prototyping of movement ideas.
Pro Tip
Use the multi-angle view to check for foot sliding, which is a common artifact in AI-generated motion. Adjust prompts to emphasize 'stable feet' if this occurs.
5
Exporting and Integrating Assets
Once satisfied with the animation, click the 'Export' button. Mootion supports industry-standard formats such as FBX and GLB. For integration into game engines like Unity or Unreal Engine, choose FBX and ensure that 'Animations' and 'Skeletal Mesh' are checked. For web-based applications or AR experiences, GLB is preferred due to its compact size and self-contained nature. After downloading, import the file into your preferred 3D software or game engine. Verify that the rig mapping is correct; in most cases, Mootion's default humanoids map directly to standard T-Pose rigs. If you used a custom model, you may need to perform a quick retargeting step in your DCC tool. The exported file contains the full animation data, including rotation and translation curves for every bone, eliminating the need for manual keyframing. This allows you to immediately test the animation in your scene and tweak root motion if necessary for your specific environment.
Pro Tip
Always test the exported FBX in your target engine immediately to ensure the scale and orientation (forward axis) match your project's coordinate system.

Iterating and Building a Motion Library
The true power of Mootion lies in its ability to rapidly generate a library of motions. Instead of creating one animation, generate a set of related actions. For example, create 'walk forward,' 'walk backward,' 'turn left,' and 'turn right' to build a basic locomotion set. You can reuse the same character model to ensure consistency across these clips. Save your successful prompts in a text document; this creates a personal 'prompt library' that you can refine over time. As you identify which phrasing yields the best results for specific actions, you can reuse and tweak these prompts for future projects. This approach significantly speeds up production workflows for indie developers and content creators who need diverse motion sets without the overhead of hiring professional animators. By treating each generation as a modular asset, you can assemble complex behaviors by blending these simple AI-generated clips in your game engine or video editor.
Pro Tip
Keep a spreadsheet of your best prompts and their corresponding outcomes to streamline future projects and maintain consistency in character movement styles.
