How to use Neural4D?

Welcome to Neural4D. This comprehensive guide will show you how to set up your account and navigate the Studio to generate 3D models, AI images, and AI videos for product design, gaming, 3D printing, content creation, and more.

How to create an account and get free credits?

Navigate to the Neural4D Studio. Once inside, click the avatar icon in the top-right corner of the screen to open the login panel.

Choose your preferred registration method: Google, X, WeChat, or Email. Once registered, the system will automatically credit your account with a free power allowance, allowing you to start generating models immediately.

How to select the right generation tool?

After entering the Neural4D Studio, all generation tools are displayed as clickable cards at the top of the page. Simply click on the card for the tool you want to use. You can also click the Studio tab in the top navigation bar and select a tool from the dropdown menu:

• Text to 3D

  Input a descriptive text prompt to generate a high-fidelity, fully textured 3D asset in seconds. Perfect for rapid prototyping and environment building.
• Image to 3D

  Upload a single photo, concept sketch, or multi-view orthographic images. The engine reconstructs it into a complete, watertight 3D mesh while preserving the original art style.
• AI Texture

  Automatically generate physically based rendering (PBR) material maps, including diffuse, normal, and roughness, for any untextured mesh using a simple text or image reference.
• Neural4D-2o

  Use our conversational AI assistant to iteratively adjust geometry, tweak lighting, or modify textures on your generated models simply by typing natural language instructions.
• AnimeArt

  Transform text or images into fully-rigged 3D anime characters. It supports native VRM export with pre-configured humanoid rigging and expression blendshapes, perfect for Vtubing and game integration.
• AI Retopo

  Reduce the polycount of high-quality models to your exact target faces. It automatically optimizes complex meshes into clean, triangle topology ready for game engines.
• AI Image Generator

  Quickly brainstorm and produce 2D concept art and reference materials directly within the studio before converting them into fully realized 3D assets.
• AI Video Generator

  Animate your static images or text prompts into cinematic, high-resolution AI video clips without requiring complex camera tracking or traditional rendering software.

How to generate and preview your creation?

After selecting a tool from the top navigation bar or the tool cards on the Studio homepage, configure your prompt or upload your file in the main workspace. Click Generate, and the system will process your request.

The completed result will appear directly in the main workspace. For 3D models, use your mouse to rotate, pan, and zoom to inspect the mesh topology and textures in real time. For images and videos, preview and download them directly from the result panel.

How to manage assets and export your work?

Neural4D automatically saves your complete generation history. You do not need to download your creations immediately.

To access your library, click the Assets tab in the top navigation bar. This panel displays all your generated 3D models, images, and videos. Click on any item to view its details or export it into your required format:

How to earn more credits for free?

To increase your generation allowance, navigate to the Invite friends option in the left sidebar. Copy your unique referral link to share with colleagues or other creators. When a new user registers through your link, additional free power credits will be automatically applied to your account.

How to access the Developer API?

For enterprise teams and developers looking to automate 3D asset pipelines, click on the API tab in the sidebar. This dashboard allows you to manage secure API keys and access technical documentation for integrating generation endpoints into your proprietary software.

How to submit feedback and feature requests?

We continuously refine our generation engine. If you encounter any structural issues or have specific feature requests for your design or development workflow, click the Feedback button at the bottom of the sidebar to submit detailed reports directly to our engineering team.
