AI 3D Model Comparison: Trellis vs Tripo vs Meshy vs Rodin vs Hunyuan
The AI 3D model generation space has exploded with innovation recently, with several platforms competing to create the most impressive, usable 3D assets from simple text or image inputs. If you're looking for state-of-the-art AI 3D generation models, five names consistently stand out: Trellis, Tripo, Meshy, Rodin, and Hunyuan. Each platform brings unique strengths to the table, but they also share common limitations – particularly when it comes to texture quality and editing capabilities.
Case Study Comparisons
To provide a fair comparison of these platforms, we've tested each with specific example types that represent common use cases. We'll look at how they perform with game props, furniture, photorealistic characters, and stylized characters.
Game Prop Example
We tested each platform's ability to generate a detailed gun model with intricate parts.
Mesh Quality Observations:
- Meshy stood out with superior mesh quality, particularly in the trigger area where hollow sections were correctly preserved
- Trellis performed reasonably well, filling only the back area of the trigger which maintained good visibility
- Tripo completely filled the hollow trigger area, reducing detail accuracy
- Hunyuan and Rodin both filled the front of the trigger area, compromising the model's accuracy
Texture Quality Observations:
- Tripo, Meshy, and Rodin produced the highest quality textures thanks to their post-processing pipelines
- Trellis and Hunyuan (open-source models) generated less refined textures that would require additional work
- All models produced textures that would need significant refinement before production use
Conclusion:
For game weapons, Meshy provided the best mesh quality with proper hollow areas, while Tripo, Meshy, and Rodin delivered superior textures. However, all models' textures would require enhancement with ideate's texture editor before production use.
Furniture Example (Chair)
We tested each platform's performance in generating a detailed chair model.
Mesh Quality Observations:
- All models performed well overall for furniture generation
- Trellis was notable for making a distinctive error in the shape of the chair's backside
- This issue with Trellis could likely be resolved by providing multiple reference images, which is possible using ideate's multi-image input feature
Texture Quality Observations:
- Meshy produced the highest quality textures out of the box
- All models created textures that serve as good starting points for refinement
Conclusion:
For furniture items, all five platforms performed adequately with Meshy delivering the best out-of-box textures. Furniture appears to be a category where these AI generators excel, requiring less post-processing than other model types.
Photorealistic Character (Female Samurai)
We tested each platform's ability to create a detailed, photorealistic female samurai character.
Mesh Quality Observations:
- Trellis produced the best results, particularly with hand details, likely due to its strong performance with t-pose character concepts
- Hunyuan came in second place for overall mesh quality
- Meshy, Tripo, and Rodin all positioned the katana incorrectly, placing it inside the character instead of on her back
Texture Quality Observations:
- Meshy, Tripo, and Rodin delivered superior face texture details due to their post-processing pipelines
- Meshy incorrectly added a beard to the female character and altered facial features from the reference image
- Trellis and Hunyuan produced lower-quality face details that would require enhancement
Conclusion:
For photorealistic characters, Trellis excelled at mesh accuracy, particularly with a t-pose reference, while Tripo and Rodin produced better textures. Facial details from Trellis and Hunyuan would need refinement with ideate's texture paint tool, which allows for targeting specific areas like faces with text prompts and reference images.
Stylized Character (Chibi Boxer)
We tested how each platform handles stylized, cartoon-like character creation with a chibi boxer.
Mesh Quality Observations:
- Hunyuan and Trellis better reproduced the smooth-shaded, cartoon look of the concept
- Tripo and Meshy added unnecessary mesh detail that detracted from the stylized nature of the character
- Rodin attempted to add facial details but struggled with elements like eyebrows
Texture Quality Observations:
- Hunyuan and Trellis produced the best results, preserving the stylized nature of the concept
- Tripo and Rodin added excessive detail that created artifacts
- Meshy deviated significantly from the reference, adding unwanted realistic details
Conclusion:
For stylized characters, the open-source models (Hunyuan and Trellis) outperformed commercial solutions by better preserving the cartoon aesthetic. This suggests that when generating stylized content, simpler texturing may actually be preferable, with targeted enhancements using ideate's texture tools.
Overall Texture Quality Findings
After examining the performance of each platform across various types of 3D models, some clear patterns emerged regarding texture quality. While mesh quality varied based on the specific use case, texture generation showed more consistent trends across all platforms.
Commercial vs. Open-Source Solutions
We observed a clear distinction between commercial platforms and open-source models:
- Commercial Platforms (Meshy, Tripo, Rodin): These solutions use sophisticated post-processing pipelines to enhance texture quality after initial generation. This results in more detailed textures, particularly for realistic models. However, these details can sometimes create unwanted artifacts or over-detailing in stylized content.
- Open-Source Models (Trellis, Hunyuan): These generate more basic textures without extensive post-processing. While they often require more refinement for photorealistic applications, their simplicity can be an advantage for stylized content where excessive detail can detract from the artistic intent.
Common Texture Issues Across All Platforms
Despite varying approaches, all five platforms share common texture limitations:
- Artifacting: Visible seams, stretching, or repeating patterns in textures appeared across all platforms
- Inconsistent details: All models struggle with maintaining uniform texture quality across different parts of a model
- Material inaccuracies: Metallic, roughness, and specular properties rarely match real-world materials without adjustment
- Limited resolution: Texture maps often lack sufficient resolution for close-up views
- Non-editable workflow: The most significant limitation is the inability to selectively edit textures without regenerating the entire model
The Texture Editing Gap
Our analysis reveals a consistent pattern: while mesh quality from AI generators is often usable with minimal editing, textures almost always require significant refinement for professional applications. This presents a workflow challenge that ideate.xyz specifically addresses.
With tools like ideate.xyz, you can:
- Import models generated by any of these platforms
- Selectively edit textures using AI-powered tools

Mesh and Texture Quality Summary
Our case studies showed clear patterns across different model types:
- For mesh quality: Trellis and Hunyuan excel at stylized characters and furniture. Trellis performed particularly well with t-pose characters. Meshy, Tripo, and Rodin tend to add more details to meshes, which works well for complex props but can be detrimental for stylized content.
- For texture quality: Meshy, Tripo, and Rodin provide more detailed textures thanks to their post-processing pipelines, while Trellis and Hunyuan produced simpler textures that may need more work but can be better starting points for stylized models.
- Most importantly: All models produce textures with artifacts that require cleanup and refinement with tools like ideate's texture paint before being suitable for production use.
