Neural4D, also called N4D by its vendor, is an AI 3D model generator that creates editable models from text, images or both. It combines model generation with texture work, mesh processing and export for other 3D applications. A separate conversational tool and CAD agent handle session edits and dimensioned parts.
Generation, conversational editing and CAD have separate workflows. The home and pricing FAQs differ on free commercial use. Training statements in the home FAQ and private-workspace help have different scopes from the terms.
Text to 3D and Image to 3D offer Triangle or Quad topology. Triangle is the default. The image guide lists Triangle at 100,000–500,000 faces and Quad at 1,000–100,000, while also stating a 50,000 default. The text guide instead lists Triangle at 10,000–100,000 and Quad at 1,000–100,000, again with a 50,000 default. These descriptions differ by entry point, and the image guide's stated default does not fit its listed Triangle range.
Texture and PBR are optional processing choices. A Quad base mesh costs 15 Credits, Texture adds 10 and PBR adds another 10, for 35 Credits with both additions. The dedicated AI Texture entry is also presented as restyling a model with a text prompt or reference image.
Pose options are Auto, A-Pose and T-Pose, with Auto selected by default. A-Pose and T-Pose are described as subscription features for humanoid characters intended for rigging or animation.
An untextured base mesh is described as taking about 90 seconds. Texture and PBR add processing stages, so a complete textured model normally takes more than two minutes. The base-mesh estimate excludes the later texture stages.
Neural4D-2o accepts a text prompt or reference image, generates a model, and takes follow-up requests in the same chat session. Its editing boundary excludes regular Text to 3D and Image to 3D results, Community models, externally uploaded models and models from another session.
Each submitted Neural4D-2o edit costs 30 Credits. Credits are returned automatically if a submitted task fails because of a server-side error.
Multi-View to 3D accepts up to six orthogonal angles: front, back, left, right, top and bottom. Its description maps texture information from the source photographs onto one UV coordinate map, including color, metallic and roughness properties. Accuracy and watertightness are vendor claims.
Remesh requires a triangle-topology input. It can target Quad output at 1,000–100,000 faces or Triangle output at 10,000–100,000 faces. Those counts are job targets, and Quad output is described as quad-dominant.
The Multicolor tool works on textured models carrying PBR textures. It identifies surface color regions, offers a default four-color Smart Color scheme, and can apply a saved personal palette of one to eight colors. Users can adjust the color count, swap filament materials or enter a custom six-digit hex color. The palette shows the share each color covers.
The saved color scheme can be exported as 3MF or GLB, with 3MF selected by default.
Coala accepts a text prompt, reference image or technical drawing as a CAD request. Its preview provides sliders for parameters such as radius, depth and width, with the model updating as they change. The agent is presented as planning a modeling task and producing an editable result.
For text to 3D, the documented prompt structure is one main object followed by its shape, parts, material and style. A desk lamp example specifies a round base, curved arm, wide metal shade and matte black finish.
The home upload control instead labels JPG, PNG and WebP with a 5 MB limit. The upload entry and guide therefore state different limits.
Neural4D's 3D printing workflow exports a model at a standardized relative scale. Absolute physical dimensions are set in the slicing software, with uniform scaling preserving the model's proportions.
Coala's examples include dimensioned organizers, phone cases and pixel-style blocks, along with gears, hinges and mounting brackets.
Coala currently exports STL; STEP and IGS are described as formats being worked on. It is explicitly optimized for industrial components with precise dimensions, not character modeling or organic shapes.
Neural4D identifies indie developers, game studios, 3D designers, virtual character creators, XR teams and academic researchers as its intended users.
Visibility is a concrete selection condition. Free users generate public models; paid subscribers can choose Private before generation. Public models may appear in the community feed or Showcase, where other users can discover them. Private keeps the model out of that public feed. A paid plan enables the choice; it does not automatically make every result private.
Neural4D requires no installation and names Chrome, Edge and Safari among supported browsers. The vendor describes compatibility with Unity, Unreal Engine, Blender, WebGL and Omniverse, and supports mobile preview and download.
The format guide distinguishes what each export carries:
The dedicated format guide calls the last extension .blend. The home FAQ instead labels it .blender.
The API-key guide says both Free and Pro users can generate and use keys. In Studio, the API panel offers key creation, a purpose label, and confirmation. Existing keys can be displayed in the dashboard or deleted to disable them immediately.
API requests consume the account's Power credits, and additional QPS limits depend on the subscription plan.
The following monthly-plan figures were captured on November 2, 2026. The plan FAQ displays separate first-month and following-month prices.
| Plan | First month | Following monthly price | Credits | Concurrent tasks |
|---|---|---|---|---|
| Free | Free plan | Free plan | 50 per week | 1 |
| Go | $9.9 | $19.9 per month | 1,500 per month | Up to 10 |
| Plus | $19.9 | $39.9 per month | 5,000 per month | Up to 50 |
| Pro | $49.9 | $99.9 per month | 25,000 per month | Up to 200 |
Credit packs are described as exclusive to subscribers and priced at $1 for 100 Credits. A separate API marketing statement explicitly quotes about $0.15 USD per high-fidelity generation call on pay-as-you-go terms. The API and subscription figures are quoted for different billing contexts.
The cancellation guide says Power Credits are added weekly while Pro is active. The home FAQ gives the monthly allowance, without specifying how weekly credits are counted against it.
The billing table lists feature-specific charges and optional additions:
| Operation | Base Credits | Listed additions |
|---|---|---|
| Generate | 10 | Texture +10; PBR +10 |
| Refine | 10 | Texture +10; PBR +10 |
| Texture | 10 | No addition listed in this row |
| Remesh | 20 | Texture +10; PBR +10 |
| Split | 40 | Merge parts +20 each time |
| Multicolor | 30 | No addition listed in this row |
The Quad generation guide has its own 15-Credit base and 35-Credit total with Texture and PBR.
Credits are deducted when a task is submitted. A completed result that is unsatisfactory does not receive a Credits refund, and submitting the task again incurs a new charge. Generations that fail because of a system error are described as receiving an automatic Credits return within a few minutes.
Cancellation is available through Account, under Plan Information, using Manage. The guide says current Pro benefits and remaining credits stay active until the exact end of the current billing cycle.
The terms provide for automatic renewal for equivalent periods at the then-current subscription price unless cancelled before the renewal date. Cancellation leaves access in place for the rest of the current term, without a prorated refund of that term's subscription fee. Service fees are otherwise non-refundable except as set out in a specific agreement, and the stated fees exclude applicable sales tax.
Meshy is another text- and image-based 3D generation service. Its current offering includes automatic character rigging, Blender and Unity plugins, and MCP and command-line entry points. These are features described by the alternative vendor, without an independent quality comparison.
Blender takes a direct modeling approach. Its tools include edge slide, collapse and dissolve, N-Gon support, grid and bridge fill, and Python scripting for custom tools and add-ons. Non-destructive modifiers apply operations without changing the base geometry. The practical distinction is access to direct modeling controls, whereas Neural4D's documented entries begin from prompts, references or a generation session.
Hidden geometry must be inferred from an input. The troubleshooting guide identifies cropped subjects, multiple objects, weak contrast, transparency, glare and motion blur as factors that make reconstruction less reliable.
The print guide still calls for orientation and support preparation. It also allows use of a slicer's repair utility when localized topological issues are flagged.
There is currently no way to cancel an active generation task.
The home FAQ describes paid users downloading textured models for production and commercial projects. It limits free downloads to untextured meshes for personal use and excludes models marked Trial from commercial use. The pricing FAQ instead says free output enters the public domain and asks for N4D attribution on commercial pages; paid subscribers are described as owning and being able to sell generated content. The descriptions of free use differ.
The vendor also publishes a Super Mario model tutorial that describes uploading a reference or fan art in Image to 3D and exporting a Super Mario STL. Specific Nintendo authorization was not established in the checked article.
For registered users posting or publishing Your Content on the service, the terms require ownership or the listed sufficient worldwide rights, including royalty-free, perpetual, irrevocable and non-exclusive rights to use, adapt, distribute and derive revenue from it. The terms require permission from the person depicted before posting their photograph or submitting it for print services.
The restrictions also prohibit making infringing content available and impersonating a person or entity. Commercial activities or sales on or through Company Properties require prior written consent under the terms. Uploading or transmitting material containing nudity, violence, sexually explicit or offensive subject matter is prohibited as determined by the company.
The terms do not claim ownership of Inputs or Outputs. They do permit automated or manual review and the use of Inputs and Outputs to train, enhance and improve AI models and related technology. The associated license is non-exclusive, irrevocable, perpetual, worldwide, royalty-free, fully paid, transferable and sublicensable.
The private-workspace help instead says reference uploads and the resulting models or videos are never used to train base foundational models such as Direct3D-S2. The home FAQ says generated assets will not be used for AI training or shared without explicit permission. The help and FAQ statements have different scopes from the broader training permission in the terms.
For Your Content, a separate terms clause grants a perpetual, irrevocable, worldwide, fully paid, royalty-free, non-exclusive and fully sublicensable license to operate and provide the service, subject to selected account settings. It also says other registered users may search for, see, use, modify and reproduce content submitted to a public area.
The privacy policy covers profile and transaction data, communications, user content and associated metadata. Automatic collection includes device characteristics, IP addresses, activity, navigation and interactions with emails; cookies and similar technologies support part of that collection.
Personal information may be shared with service providers, payment processors, user-designated third parties, affiliates, business and marketing partners, professional advisers, authorities and business transferees.
Retention serves the collection purposes, legal, accounting and reporting obligations, claims and fraud prevention. When information is no longer required, it may be deleted, anonymized or isolated from further processing. The asset-deletion help separately describes deleting a reference, generated model or project as permanently erasing it from active servers.
The privacy policy names processing and storage in United States facilities and possible transfer to other jurisdictions with different protections. It excludes information processed on behalf of enterprise customers, whose agreements may govern that processing instead.
Registration requires being at least thirteen or the country's minimum age for consent, having legal capacity to contract and not being legally barred from use. The privacy policy says the service is intended for ages 13 and up. If Neural4D learns it collected a child's data without legally required parent or guardian consent, it says it will comply with applicable deletion requirements.
A white base mesh is the expected result when Texture was not selected. When Texture or PBR was selected, all processing stages must finish before the completed saved asset is checked. The troubleshooting guidance treats a completed asset still missing selected texture output as an issue to report through Feedback.
The task can be checked in Assets Library and in Account Usage History, including its charge and any Credits Return entry. Complex work may take longer than the basic estimate, so elapsed time alone does not establish failure.
For Stripe online payments, Account → Manage → Invoice History provides a receipt or invoice download. Mainland China VAT invoice requests are handled through support with the account and invoicing details.
