Vita3D User Guide

The Vita3D user guide provides step-by-step instructions to build stunning models, add textures, rig characters, create animations, and capture motions effortlessly, perfect for beginners and pros alike.

Introduction to Vita3D

Welcome to Vita3D, an all-in-one 3D powerhouse designed to revolutionize your creative process. Vita3D integrates 3D modeling, texturing, rigging, animation creation, and motion capture into one comprehensive toolset. Whether you’re a seasoned professional or just starting out, our platform is tailored to simplify your workflow, boost productivity, and bring your visions to life with unparalleled ease and efficiency.

Vita3D includes everything you need to go from concept to animated 3D asset:

3D Modeling: Generate 3D models from reference images or simple sketches.

Texturing: Automatically create detailed textures from photos.

Rigging: Add a skeleton to your model so it’s ready for animation.

Animation: Bring your model to life using pre-built motions or text-to-animation prompts.

Motion Capture: Upload a video and extract realistic movement to drive your character.

Assets: Organize and manage all your models, textures, and animations in one place.

Tasks: Track your ongoing and completed jobs—so you always know what’s rendering and what’s ready to use.

In the sections below, we’ll walk you through each feature step by step, along with practical tips to get the best results. Follow these guidelines, and you’ll consistently get cleaner geometry, smoother rigs, and more lifelike motion.

3D Modeling

Vita3D offers three ways to create or bring in 3D models:

Image to 3D: Generate a 3D model from a single photo.

Scribble to 3D: Turn a rough sketch into a 3D model using a text prompt.

Upload Models: Import models you’ve created in other 3D software.

Image to 3D

You can upload a PNG or JPG image (up to 20 MB) to generate a 3D model. For the best results, follow these guidelines:

If you’re creating a human character, we recommend:

When generating the model, you can choose between Default or set a maximum face count. Higher face counts produce more detailed geometry but use more memory and may impact performance. Since the ideal face count varies by object type, we recommend sticking with Default—our AI will automatically pick the right level of detail for your model.

How to create a 3D model from an image:

1. Go to Vita3D > Model > Image to 3D.
2. Upload your image and adjust the face count if needed.
3. Click Generate.

💡 Tips

• The initial model may look basic, but it often improves significantly after adding textures.
• Dark or underexposed areas in your image can cause holes or missing parts in the generated model.

Scribble to 3D

Turn a hand-drawn sketch into a 3D model with the help of a text prompt. Supported formats: PNG or JPG (up to 20 MB).

How to create a 3D model from a sketch and prompt:

1. Go to Vita3D > Model > Scribble to 3D.
2. Upload your sketch and enter a clear description (e.g., “a cartoon fox with big ears, fluffy tail, and blue eyes”).
3. Click Generate.

Upload Models

Already have a 3D model? You can import it directly into Vita3D. We support the following file formats:

• .fbx
• .vrm
• .glb

Once uploaded, you can rig, texture, or animate it just like any AI-generated model.

Adding Textures

Vita3D lets you add realistic textures to your 3D models using a reference photo. The system supports PBR (Physically Based Rendering) materials, so your results will have natural lighting, depth, and surface detail, like metal, fabric, or skin.

We support PNG or JPG images (up to 20 MB). For the best results, ensure that the subject, especially facial features if applicable, occupies a significant portion of the image. Close-up shots are preferable over distant or cluttered photos.

When adding textures, there are two optional settings you can enable:

Remove background

Automatically masks out the background to focus the texture on your subject. Recommended for cleaner results.

Remesh model

Temporarily converts your model to a ~40k-face mesh during texturing (then restores the original topology). This speeds up texture generation.

How to add texture:

Make sure you’ve selected the target model in the Model panel before starting, then follow the steps below:

1. Go to Vita3D > Texture.
2. Upload your image and give the task a name.
3. (Optional) Check Remove background and/or Remesh model.
4. Click Add Texture.

Rigging

Rigging adds a skeleton to your 3D model so it can be animated. Vita3D offers two rig types, depending on what you’re creating:

Humanoid

Designed for human-like characters. After rigging, you can preview built-in example animations (like walking or waving) to test how well the bones align with your model.

Articulation

A flexible rig for non-human subjects, such as animals, robots, or props. This type doesn’t support example animations, but it gives you full control for custom animation or export.

💡 Tip: Use Humanoid only for bipedal, human-proportioned characters. For everything else—four-legged creatures, furniture, vehicles—go with Articulation.

How to rig your model:

1. Go to Vita3D > Rig.
2. Select your rig type (Humanoid or Articulation), then click Auto Rig.
3. Once rigging is complete, you can (if using Humanoid) choose an example animation to preview the result.

Creating Animations

Vita3D lets you create animations in three ways:

Text-to-Animation: Describe a motion in plain language, and AI generates a matching animation.

Default animations: A library of ready-to-use motions (e.g., idle, walk, jump).

Motion capture clips: Animations created from uploaded video via motion capture.

Writing effective prompts

For best results with Text-to-Animation, be as specific and descriptive as possible. Instead of “wave,” try:

“A friendly wave with the right hand, elbow slightly bent, arm moving smoothly from side to front.”

The more detail you provide—about speed, style, body parts, or mood—the better the result.

💡 Tip: Turn on Smart Prompt if you’re unsure how to phrase your motion. It suggests improvements to help the AI understand your intent.

How to create and apply an animation:

⚠️ Make sure you’ve selected a rigged model before starting.

1. Go to Vita3D > Animate.
2. Enter your animation prompt.
3. (Optional) Enable Smart Prompt Assist for guided suggestions.
4. Click Generate.
5. Once complete, go to the Animation Library, select your new clip, and apply it to the model.

Motion Capture

Vita3D lets you capture motion from video and apply it directly to your own rigged models or to built-in characters like X Bot, Y Bot, or the Skeleton.

For accurate and clean motion capture, please use a video that meets these criteria:

💡 Tip: Shoot against a plain background and wear fitted clothing to help the system track movement more reliably.

Once processed, your motion capture clip can be exported in industry-standard formats:

• FBX (includes mesh and animation—ideal for game engines)
• BVH (skeleton-only animation—great for retargeting)
• Or both formats at once

How to capture motion from a video:

1. Go to Vita3D > Mocap.
2. Select the target character (your own rigged model or a built-in one like X Bot, Y Bot, or Skeleton), then upload your source video.
3. Depending on your account type, your video may be subject to a maximum length limit. If needed, trim the clip to the desired segment and click Capture.
4. In the settings window that appears, adjust motion capture options as needed, then click Generate.

💡 Tip: Keep your clip short and focused on the motion you want—this speeds up processing and often improves accuracy.

Managing Assets

The Assets section is your central hub for all creations in Vita3D, including:

• 3D models
• Textured models
• Rigged characters
• AI-generated animations
• Motion capture clips

Each asset is marked with a small icon in the top-right corner of its preview so you can instantly tell whether it’s a model, animation, or mocap clip.

From here, you can:

• Search your library by name
• Copy, rename, or move assets into folders
• Download files (in supported formats like FBX, GLB, BVH, etc.)
• Delete items you no longer need

Everything you create—whether from modeling, texturing, rigging, or animation—automatically appears here, organized and ready to use.

Viewing Tasks

When you click Tasks, a sidebar slides in from the right, showing all your recent jobs from the past three days, including both completed and in-progress tasks.

To load a result into the viewport, simply click the Load button next to any task.

💡 Note: The Tasks panel only shows recent activity. To access all your creations—including older models, animations, and motion clips—go to the Assets section.
