Trellis 2 vs Hunyuan 3D vs TripoSR (2026)

"What is the difference between Trellis 2 and Hunyuan 3?" is one of Google's top People Also Ask questions for 3D generation, and the answers floating around are vague. "Trellis is better quality, Hunyuan is faster" is true but useless when you are trying to decide which to install tonight.

This comparison puts Trellis 2, Hunyuan 3D (Hunyuan3D-2), and TripoSR side by side on the dimensions that actually matter: output fidelity, VRAM, speed, PBR textures, ComfyUI support, and licensing. By the end you will know which one fits your GPU and your goal.

TL;DR

You want…	Pick
Best fidelity + PBR textures, you have the GPU	Trellis 2
Fast, lower VRAM, commercially friendly	Hunyuan 3D
Speed above all, single-image, lightweight	TripoSR

For most users in 2026, Trellis 2 wins on quality and Hunyuan 3D wins on practicality. TripoSR is the legacy speed pick, increasingly outclassed.

The Three Models at a Glance

Hunyuan3D-2 (shown above) is Tencent's competitor to Microsoft's Trellis 2. Both are image-to-3D, but they trade off differently on fidelity, VRAM, and speed. Source: tencent/Hunyuan3D-2.

Model	Maker	Size	Min VRAM (full)	Strength
Trellis 2	Microsoft	4B	16–24GB	Fidelity, PBR
Hunyuan 3D (Hunyuan3D-2)	Tencent	~1B	8–16GB	Speed, low VRAM
TripoSR	Stability + Tripo	~1B	6–8GB	Raw speed, single image

Trellis 2

Maker: Microsoft (microsoft/TRELLIS.2-4B on Hugging Face)

Trellis 2 is the fidelity leader. It uses Structured Latents (SLAT) to separate geometry from appearance, which lets it bake genuinely good PBR textures, Base Color, Roughness, Metallic, onto clean meshes. For hero assets and anything where texture quality matters, nothing else in the open-source space matches it in mid-2026.

Pros:

• Best-in-class fidelity
• Strong PBR texture output
• Image-to-3D and text-to-3D
• Active ComfyUI community (three wrappers)

Cons:

• Heavy, 16–24GB VRAM for the full model
• Painful install on Windows (see the troubleshooting master list)
• Research license, check terms before commercial use

Hunyuan 3D (Hunyuan3D-2)

Maker: Tencent

Hunyuan 3D is the practical pick. At roughly 1B parameters, it runs on far less VRAM (8–16GB) and generates noticeably faster than Trellis 2. The fidelity ceiling is slightly lower, but for game props, environment assets, and rapid iteration, the difference rarely matters, and the speed/VRAM advantage often does.

Pros:

• Lower VRAM (8–16GB)
• Fast generation
• More commercially permissive licensing
• Solid ComfyUI support

Cons:

• Slightly lower fidelity ceiling than Trellis 2
• PBR quality good but not best-in-class

TripoSR

Maker: Stability AI + Tripo

TripoSR was the 2024 speed champion, sub-second single-image-to-3D on modest hardware. In 2026 it is still the lightest option (6–8GB VRAM) but its output fidelity has been overtaken by both Trellis 2 and Hunyuan 3D. It remains relevant only for users on very weak hardware who need a mesh now.

Pros:

• Extremely fast
• Very low VRAM (6–8GB)
• Simple, stable pipeline

Cons:

• Outclassed on fidelity by Trellis 2 and Hunyuan 3D
• Weaker textures
• Less active development vs the other two

Fidelity Comparison

On identical input images, the typical 2026 ranking for output quality:

1. Trellis 2: cleanest topology, best PBR textures, fewest artifacts (especially with the multiview front-end)
2. Hunyuan 3D: close second, occasionally indistinguishable on simple props
3. TripoSR: visibly rougher, more cleanup needed

The gap narrows on simple subjects (a mug, a crate) and widens on complex ones (characters, vehicles, organic shapes). If your work is mostly simple hard-surface props, Hunyuan 3D saves you VRAM with minimal quality loss. If you do characters or hero assets, Trellis 2 is worth the weight.

A r/StableDiffusion thread argues Trellis 2 is "already getting dethroned", true for raw speed, but as of mid-2026 Trellis 2 still leads on PBR texture quality.

VRAM & Speed Comparison

Model	VRAM (full)	VRAM (quantized)	Speed	Time per mesh (est.)
Trellis 2	16–24GB	8GB (GGUF)	Slow	~3.5 min (RTX 4070 Ti Super, 1024)
Hunyuan 3D	8–16GB	6GB	Fast	~30–60s (mid-range)
TripoSR	6–8GB	—	Very fast	<10s

ComfyUI Support

All three have ComfyUI wrappers, but the ecosystem maturity differs:

• Trellis 2: Three active wrappers (visualbruno, PozzettiAndrea, if-ai). See ComfyUI Trellis Node Packages Compared. Largest community, most workflows, most troubleshooting.
• Hunyuan 3D: Mature, well-documented integration. Often the easier first install.
• TripoSR: Stable but older; fewer updates.

Licensing

Model	Commercial use
Trellis 2	Research license, verify terms
Hunyuan 3D	More permissive for commercial
TripoSR	Permissive

If you are generating assets for a commercial product, Hunyuan 3D is usually the safer licensing choice. Always read the actual license on the model repo before shipping.

Decision Framework

Your situation	Recommendation
24GB GPU, want the best quality	Trellis 2
8–16GB GPU, want quality + speed	Hunyuan 3D
6–8GB GPU, just need a mesh	TripoSR (or Trellis 2 GGUF)
Commercial product, licensing-sensitive	Hunyuan 3D
Characters / hero assets	Trellis 2
Rapid prototyping	Hunyuan 3D

Real-World Selection Examples

Abstract comparisons only go so far. Here are concrete scenarios and the model each points to.

Indie game dev, 8GB GPU, needs 50 environment props this month. Pick Hunyuan 3D. The VRAM fits, the speed lets you iterate through 50 assets, and the fidelity is plenty for background environment dressing. Trellis 2 on 8GB means GGUF at 512, which is slow and rough.

VFX studio, 24GB+ workstations, hero asset for a close-up shot. Pick Trellis 2 with multiview. The fidelity and PBR quality survive scrutiny at close range. The install pain is a one-time cost amortized across the studio.

Hobbyist, 12GB GPU, wants the best single mesh from one photo. Try Trellis 2 first (full model at 1024 fits in 12GB). If install fails or it is too slow, fall back to Hunyuan 3D. Both are free, so the cost of trying both is just time.

Commercial product, shipping 3D assets to paying customers. Lean Hunyuan 3D for licensing clarity, unless your legal team clears Trellis 2's research license. Do not assume any model's license, read it.

Rapid prototyping, need a mesh in under a minute. TripoSR. Nothing else here is close on raw speed. Accept the lower fidelity as the price of speed.

Output Comparison on the Same Input

When you feed the same clean image (say, a single prop on a white background) to all three at their comfortable resolutions, the differences cluster predictably:

• Geometry cleanliness: Trellis 2 (cleanest) > Hunyuan 3D (close) > TripoSR (rougher)
• Texture fidelity: Trellis 2 (best PBR) > Hunyuan 3D (good) > TripoSR (flat)
• Back-of-object guess quality: Trellis 2 + multiview (best) > Trellis 2 single-view > Hunyuan 3D > TripoSR
• Time to first mesh: TripoSR (<10s) > Hunyuan 3D (30 to 60s) > Trellis 2 (3+ min)
• Cleanup needed before engine-ready: TripoSR (most) > Hunyuan 3D (moderate) > Trellis 2 + refiner (least)

The decision is rarely "which is best overall." It is "which trade-off matches my GPU, deadline, and quality bar." Use the table above, not a single ranking.

Frequently Asked Questions

What is the difference between Trellis 2 and Hunyuan 3?

Trellis 2 (Microsoft, 4B) offers higher fidelity and better PBR textures but needs 16–24GB VRAM. Hunyuan 3D (Tencent, ~1B) is faster, lighter (8–16GB), and more commercially permissive, with a slightly lower fidelity ceiling.

Is Trellis 2 better than Hunyuan 3D?

On fidelity and PBR texture quality, yes. On speed, VRAM efficiency, and licensing, Hunyuan 3D wins. There is no overall winner, pick by your constraints.

Can TripoSR match Trellis 2 quality?

No. TripoSR is faster and lighter but visibly rougher. For quality, Trellis 2 and Hunyuan 3D both outclass it in 2026.

Which is best for commercial use?

Hunyuan 3D is typically the most commercially friendly. Always verify the current license on the model repo before shipping.
