Neural4D is a browser-based AI 3D generator that creates clean, watertight polygonal meshes directly from a single reference photo. Stop struggling with complex photogrammetry software or un-editable Gaussian point clouds. Get game-ready assets in just 90 seconds.

Native Mesh Generation Engine

What is Gaussian Splatting? It is an advanced 3D reconstruction technique that uses colored points (splats) to represent scenes. While visually stunning, these point clouds cannot be animated or 3D printed easily. Neural4D provides a superior alternative by generating clean, quad-dominant meshes directly using the Direct3D-S2 engine.

Clean Quad Topology

Generate pure, manifold polygons that behave like traditionally modeled assets, entirely sidestepping point cloud limitations.

No Camera Rig Needed

Ditch the tedious 100-angle photo shoots. Reconstruct high-fidelity 3D volume from a single reference image or text prompt.

Game Engine Native

Export directly to Unreal Engine 5 or Unity via standard .FBX and .GLB without relying on cumbersome splatting plugins.

Why Choose Meshes Over Splats?

Import Neural4D generated meshes into Unreal Engine 5 instead of Gaussian Splatting point clouds

Unreal Engine 5 Pipelines

Skip the complex Gaussian Splatting UE5 plugins. Neural4D generates native .fbx and .glb files that drag-and-drop directly into your game engine with full PBR material support.

3D printing models generated by Neural4D instead of unprintable splatting files

3D Printing Ready

Unlike 3DGS point clouds which are hollow and unprintable, Neural4D generates completely watertight (manifold) meshes. Export directly to .stl and load into your slicer immediately.

Rigging and animating 3D characters generated from images

Character Rigging & Animation

You cannot rig a Gaussian Splat. Neural4D provides quad-dominant topology, allowing you to easily auto-rig characters in Mixamo or Blender for immediate animation.

Editing AI 3D meshes in Blender, an alternative to splatting editors

Full Blender Editability

Standard 3D splatting files require specialized editors. With our Direct3D-S2 meshes, you retain full control over vertices, edges, and UV maps using native Blender tools.

A Faster Workflow Than 3DGS

1. Skip the 100-Photo Capture

Unlike Gaussian Splatting or Photogrammetry which requires walking around an object capturing dozens of images, Neural4D requires only a single photo to understand the 3D volume.

Single image 3D generation bypassing the need for multi-view photo capture

2. Volumetric Inference (Not Splats)

Our engine reconstructs solid polygonal geometry in the cloud. We don't project colored spheres into a viewing space; we generate authentic vertices, edges, and faces that interact accurately with lighting.

3. Export directly to UE5 or Unity

No need for Luma AI plugins, PlayCanvas integrations, or custom rendering pipelines. Download your .fbx or .glb and drop it directly into your standard game engine material workflow.

Gaussian Splatting vs Mesh FAQs

What is the difference between Gaussian Splatting and 3D Meshes?

Gaussian Splatting uses millions of colored points to render a 3D view, which looks great but cannot be easily edited. 3D Meshes (like those generated by Neural4D) are solid objects made of polygons, which are required for 3D printing, physics simulations, and game engines.

Can I import Gaussian Splats into Unreal Engine?

Yes, but it requires specialized plugins (like Luma AI) and custom materials. Neural4D generates native .FBX and .GLB meshes that you can drag-and-drop into Unreal Engine 5 with zero plugins.

Is a mesh better than a splat for 3D printing?

Absolutely. Gaussian Splats are hollow point clouds and cannot be sliced by 3D printers. Neural4D generates watertight, manifold meshes that can be exported as .STL and printed immediately.

How does Neural4D generation speed compare to 3DGS?

Training a high-quality Gaussian Splatting model often takes 15-30 minutes and requires dozens of photos. Neural4D generates a complete 3D mesh from a single photo or text prompt in just 90 seconds.
