Hunyuan3D 3.0 - Tencent Hunyuan's latest 3D generation model

Author: AI小集 · Original source: AI工具集

What is Hunyuan3D 3.0

Hunyuan3D 3.0 is Tencent's latest release of an advanced3D generation model. It adopts the pioneering 3D-DiT hierarchical sculpting technology, capable of generating ultra-high-definition 3D geometric structures, with modeling precision improved by 3 times, geometric resolution up to 1536³, and support for 3.6 billion voxel modeling. It breaks through the bottlenecks of traditional 3D generation, balancing overall structure and local details, making the generated models have sharp edges and clear details. In character generation, Hunyuan3D 3.0 has undergone specialized optimization, enabling fine facial remodeling, clearer and more three-dimensional facial features, natural and smooth character posture, solving the common "abstract face" problem in previous 3D models. The model optimizes texture generation, further improving texture adherence and geometric alignment precision, making surface textures more realistic and delicate.

Main Features of Hunyuan3D 3.0

  • Ultra-high-definition 3D geometry generation: Adopts 3D-DiT hierarchical sculpting technology, modeling precision improved by 3 times, geometric resolution up to 1536³, supports 3.6 billion voxel modeling, balancing overall structure and local details, generating models with sharp edges and clear details.
  • Character modeling optimization: Specialized optimization for character generation, achieving fine facial remodeling, clear and three-dimensional facial features, natural and smooth character posture, solving the "abstract face" problem.
  • Complex structure processing: Hierarchical generation strategy builds the underlying structure and then finely sculpts details, enhancing understanding and restoration of invisible areas, improving the generation effect of complex geometric structures.
  • Texture generation improvement: Optimizes texture adherence and geometric alignment precision, achieving precise texture mapping and fitting, making model surface textures realistic and delicate.
  • Multi-scenario application support: Suitable for game development, film and television production, e-commerce, social applications, and industrial design, etc., improving development efficiency, saving time and cost.

Technical Highlights of Hunyuan3D 3.0

  • Pioneering 3D-DiT hierarchical sculpting model: Breaks through traditional technical bottlenecks, balancing overall structure and local details, achieving ultra-high-definition 3D geometry generation, with results maintaining industry SOTA.
  • Specialized optimization for character generation: Significantly improves modeling precision, achieving fine facial remodeling, making facial features clear and three-dimensional, character posture natural and smooth, saying goodbye to the "abstract face" problem.
  • Complex geometric structure generation: Adopts a hierarchical generation strategy, first building the underlying structure, then gradually finely sculpting details, enhancing understanding and restoration of invisible areas.
  • Texture generation optimization: Further optimizes texture adherence and geometric alignment precision, ensuring texture details faithfully follow design intent, achieving more precise texture mapping and fitting.

How to use Hunyuan3D 3.0

  • Through theTencent Hunyuan 3D Creation Engineofficial website：
    • Text-to-3D: Visit the official website, click "Text-to-3D", enter a description, select a style, check "Low-Poly mode", click generate, after generation you can download OBJ/FBX/GLB format files, supporting direct import into Blender for editing.
    • Image-to-3D: Click "Image to 3D", upload a front view of the object, check "Remove Background" for automatic cutout (required for non-transparent backgrounds), select "Generate Shape and Texture" to generate geometry and texture simultaneously, and after downloading the model, you can use the Sketch to 3D feature to add details.
    • Sketch to 3D: Upload a hand-drawn sketch and it will be automatically converted into a 3D model, suitable for concept design.
    • Multi-view input: Upload 4 images of the same object from the front/back/left/right, improving geometric accuracy by 40%. Descriptions of complex objects need to be specific.
    • Quick animation: After generating the model, enter the "3D Animation" lab, select a preset action (jumping, martial arts, etc.), automatically rig the skeleton, and export GIF/FBX.
    • Industrial-grade applications: Upload a white model, enter a material description (such as "frosted plastic material"), replace the texture with one click, generate PBR maps, and support UV alignment detection.
  • Use viaTencent Yuanbao APP's "3D Character Dream Factory" feature：
    • Upload photo: Open the Tencent Yuanbao APP, tap "Discover", search for "3D Character Dream Factory", select a template, and upload a photo with clear facial features from the front, a solid-color background, and a resolution of at least 500×500, avoiding glasses/hand gestures/accessories.
    • AI-generated model: Wait about 6 minutes, and the system will automatically blend the avatar onto the template body. If the result is unsatisfactory, check whether the background is cluttered or the face is obstructed, and check "PBR Material Texture" to improve the texture of the skin/clothing.
    • Export and print: Copy the generated OBJ format link, import it into 3D printing software (such as Cura), adjust the size, and directly print a physical figurine.
  • Use via the Hunyuan 3D AI Creation Engine：
    • Multi-view input: The new version of the Hunyuan 3D AI Creation Engine supports multi-view input, and the generated model's material details are more realistic, meeting the needs of various styles.
    • Multi-format compatibility: The newly upgraded Hunyuan 3D AI Creation Engine connects with mainstream formats on the market. OBJ, FBX, GLB, STL, USDZ, MP4 and other output methods can be switched with one click, seamlessly connecting to application scenarios.

Application scenarios of Hunyuan 3D 3.0

  • Game development: It can be used to quickly generate 3D models such as characters and scenes in games, improving game development efficiency.
  • Film and television production: It helps the film and television industry quickly create realistic 3D scenes and character models, saving production time and cost.
  • E-commerce: Generate high-quality 3D models for e-commerce products to improve the user experience.
