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 is optimized for watertight reconstruction and high-resolution structural integrity.
Sparc3D (Portrait): Specialized in the geometry of the human head and shoulders, providing superior facial features.
Sparc3D (Standard): Excellent for 3D printing or complex mechanical parts where maintaining a "closed" (watertight) mesh is critical.
Tripo 2.5
Optimized for photorealistic, object-centric assets.
Tripo 2.5 (Standard): Works from a single image, producing clean meshes with PBR support and HD resolutions (up to 2048x2048).
Tripo 2.5 Multi-View: Improves spatial consistency and reduces distortion by utilizing 2 to 4 images.

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.
Observe the gradual increase in mesh resolution from extra-low to high density in this other example:
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
Developed by Microsoft, Trellis is based on the Structured LATent (SLAT) representation, which encodes structural and textural information jointly. It performs particularly well when given multiple reference images (up to 10) and excels in geometry-driven tasks with strong surface continuity.
Trellis excels in stylized looks, such as toon shading, low-poly geometry, or illustrative designs.
Accepts a wide variety of reference images and 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.
Sparc3D
Focused on high-resolution reconstruction and preserving fine details.
Sparc3D (Portrait): Specialized in capturing the subtleties of human faces and anatomy.
Sparc3D (Standard): Excellent for creating "watertight" meshes, ideal for 3D printing and applications requiring closed surfaces.
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.
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.
