Which 3D Model Should You Use?
Choosing the right model depends on your technical priorities, whether you are optimizing for realism, speed, stylization, or reconstruction fidelity.
Hunyuan 3D (v3.0, v2.1, & Specialized)
Developed by Tencent, this family uses a flow-based diffusion model (Hunyuan3D-DiT) for geometry and high-resolution synthesis for textures.
Hunyuan 3D 3.0 (Pro/Multiview): The current flagship for high-resolution production.
Hunyuan 3D 3.0 (Sketch): Specifically tuned to interpret 2D sketches and line art into 3D volumes, making it ideal for early-stage concepting.
Hunyuan 3D Part: Automatically recognizes and generates separate meshes for different parts of an object (e.g., separating a chair's legs from its seat), simplifying the rigging and animation process.
Hunyuan 3D 2.1: A versatile, reliable version for high-quality assets with moderate processing times.

Sparc3D
Sparc3D 2.0 is optimized for watertight reconstruction and high-resolution structural integrity.
Sparc3D 2.0 (Portrait): Specialized for human subjects, focusing on facial coherence and volume stability.
Sparc3D 2.0 (General): Optimized for production assets and 3D printing with resolutions up to 1536³ Pro.

Rodin Family (Gen-2 and Gen-1)
Designed for high-fidelity multi-view image-to-3D synthesis.
Rodin Gen-2: Represents the state-of-the-art in surface realism, rivaling actual scans and offering optimized geometries for animation.
Rodin Gen-1: Versatile for using multiple reference images, supporting up to 10 images in Concat or Fuse mode.

PartCrafter (Generate in parts)
PartCrafter is the first open-source, image-to-3D generative model that transforms a single RGB image into several 3D meshes, semantically meaningful, all in one step. It can produces explicit meshes suitable for further editing, animation, or 3D printing—no segmentation or manual intervention required.
Unlike existing “single-block” AI mesh generators, PartCrafter separates your input object into defined components it can recognize (such as arms, wheels, panels, etc). These parts are cleanly segmented, each with its own geometry.
Works from just one image.
Generates 2 to 16 3D meshes.
Remove Background option.
Trellis
Trellis 2 utilizes a 4B parameter DiT pipeline for high-resolution PBR asset generation.
Trellis 2: Optimized for complex topologies and transparent materials with 1536³ resolution and 4K textures.
Trellis (Legacy): Based on SLAT architecture, this model remains effective for stylized designs and multi-view reconstruction (up to 10 images).
Direct3D-S2
Developed by NJU-3DV, Direct3D-S2 is designed for scalability. It uses Spatial Sparse Attention (SSA) to generate voxel-based models up to 1024³ resolution while remaining computationally efficient.
It produces acceptable detail for props or environments, though mesh fidelity can drop with increasing complexity.
Well-suited for terrain, urban layouts, or environmental structures where voxelization and structure outweigh texture polish.
Meshy Suite
Following the latest updates, the Meshy family provides a comprehensive workflow for rapid iteration:
Generation: Use Text-to-3D or Image-to-3D to create base assets in seconds.
Refinement: Apply Remesh to optimize the asset's performance for game engines.
Appearance: Use Retexture to apply professional PBR maps and materials.
Animation: Use Rigging to instantly prepare your character meshes for animation.
SAM3D Suite
SAM3D by Meta provides a modular pipeline for reconstructing assets and human subjects from 2D images.
SAM3D Objects: Isolates and reconstructs individual props from a scene using text, point, or box prompts.
SAM3D Human Body: Generates standardized 3D body geometry for anatomical visualization and character foundations.
SAM3D Align: Orchestrates and aligns body meshes and object props within a shared 3D space to maintain spatial relationships.
Voxel Crafter 1.0
Specifically designed to output "blocky" voxel art, perfect for games with a retro or sandbox aesthetic.
Conclusion: Choosing the Right Tool for the Task
The landscape of generative 3D is evolving rapidly, and the variety of models available on Scenario ensures that you have the right tool for every stage of your creative pipeline. Whether you are aiming for the high-fidelity, production-ready outputs of Hunyuan 3D 3.0 Pro and Rodin Gen-2, or the stylized, geometry-focused strengths of Trellis, the key to success lies in matching the model to your specific project requirements.
For high-end realism: Prioritize the newest generations like Hunyuan 3.0 and Rodin Gen-2.
For rapid prototyping: Tripo 2.5 and the Meshy Suite offer the best balance of speed and quality.
For specialized needs: Use Sparc3D for 3D printing or Hunyuan Part for modular assets ready for animation.
Because AI generation is inherently iterative, we recommend testing your primary reference image across multiple models. By comparing the geometry, texture resolution, and mesh topology side-by-side, you can find the perfect fit for your game, environment, or digital twin.
