It aims to streamline content creation for various industries by automating time-consuming aspects of 3D modeling, including the generation of watertight 3D game props with PBR materials and 3D printable STL files.

features

Key Features of Neural4D

Neural4D provides a suite of AI-driven tools within its '3D Studio' to facilitate 3D asset creation and optimization. These features are designed to support various stages of the content pipeline, from initial concept to game-ready assets and 3D printable models.

  • Text to 3D: Generates 3D meshes from textual descriptions for rapid prototyping and environment construction.
  • Image to 3D: Reconstructs 3D models from single or multiple 2D reference images, preserving original art styles.
  • AI Texture: Applies Physically Based Rendering (PBR) materials, including diffuse, normal, and roughness maps, to uploaded meshes using 2D references or text prompts.
  • AI Retopo: Automatically generates clean, quad-dominant topology for game engine export, reducing polycount to a specified target.
  • AnimeArt: Creates VRM-format anime characters from text or images, pre-configured with humanoid rigging and expression blendshapes for VTubing and game development.
  • 2D Generation: Includes an AI Image Generator for text-to-image creation and an AI Video Generator for text-to-video production.
  • Watertight Mesh Generation: Ensures structural integrity for 3D printable STL files and game props.
  • Automatic Rigging & Animation: Provides clean skeletons, smooth skin weights, and export-ready animation files for generated models.
