Microsoft Presents "TRELLIS.2": An Open-Source, 4b-Parameter, Image-To-3D Model Producing Up To 1536³ PBR Textured Assets, Built On Native 3D VAES With 16× Spatial Compression, Delivering Efficient, Scalable, High-Fidelity Asset Generation.

Posted by 44th--Hokage@reddit | LocalLLaMA | View on Reddit | 75 comments

TRELLIS.2 is a state-of-the-art large 3D generative model (4B parameters) designed for high-fidelity image-to-3D generation. It leverages a novel "field-free" sparse voxel structure termed O-Voxel to reconstruct and generate arbitrary 3D assets with complex topologies, sharp features, and full PBR materials.

Model was released four months ago.

michaelsoft__binbows@reddit

Has it been this good for this long? Wow

[-]

Relative_Bit_7250@reddit

Yeah, it's pretty much the best when talking about 3D generative models. The only problem is that it's a real pain in the ass to install, at least on Linux, don't know about Windows. I'm still managing to make it work inside a comfyui environment to this day.

[-]

EbbNorth7735@reddit

I've been working on getting it working for the last two days on Windows with Qwen3.6 27B. I keep whipping harder and harder but Qwen just can't seem to get it right

[-]

Relative_Bit_7250@reddit

Eh, good luck. Tried the same thing with Gemini 3 pro, deepseek, Claude... Nothing. Gemini kept giving me the old "you're perfectly right" or "I understand your frustration". No, Gemini, you don't. You really don't.

OptimizeLLM@reddit

It was a couple months ago now, but Opus 4.6 one-shot the Trellis.2 install as part of an experiment making a VR interface for Trellis using Godot. Worked fine on Ubuntu

[-]

Exciting_Variation56@reddit

Please tell me more this is my whole shiz I’m tryna use Godot for game dev ad AI can help reduce the time to working model but I want to be conscious of impact on the power grid and be a responsible local hosted

MINIMAN10001@reddit

I mean isn't it usually more energy efficient to outsource due to horizontal scaling increasing relative throughput? I always assumed that's why they can do it cheaper. Just be aware of how much money you're spending and you should more or less have a general understanding of your electrical cost.

[-]

Exciting_Variation56@reddit

Cheaper yes absolutely

But not better for people. The servers hosting these are repeatedly shown to be detrimental to the surrounding environments and communities

[-]

mirror_truth@reddit

Data centers are more efficient than anything you can run at home, just like generating electricity at a power station then transmitting it to millions of homes is more efficient than everyone running a generator in their backyard.

[-]

Exciting_Variation56@reddit

I agree again

And yet supporting those data centers pollutes their nearby waters, hurts the surrounding communities, and supports financially companies I don’t agree with

[-]

More-Curious816@reddit

Since you got it working, how was the quality of the outputs? Also how much vram it ate

[-]

EbbNorth7735@reddit

The models just started loading on my HW. I don't know if the model server was successful yet but I'd like to pretend it got there.

[-]

MedicalScore3474@reddit

Looks like someone else already did it, but the repository authors haven't reviewed/merged it yet: https://github.com/microsoft/TRELLIS.2/pull/100

[-]

EbbNorth7735@reddit

I need to not rely on AI so much. This looks necessary. I'll look into pulling it into my docker file

[-]

michaelsoft__binbows@reddit

the 27B are smart but not smart enough to be worth the time trying to build bleeding edge software like this with...

[-]

EbbNorth7735@reddit

Haha what? I've built a few pretty good apps

[-]

michaelsoft__binbows@reddit

i'm not saying it's impossible but it's kinda like mowing a football field with a push mower. Go ahead and knock yourself out if that's what you really wanna do.

[-]

EbbNorth7735@reddit

If 6 minths ago we thought Opus 4.5 was amazing I'm not sure why we wouldn't think the latest models are unusable

[-]

eugene20@reddit

That's brilliant news. The last version I tried the other day was a comfy install but it needed python 3.12 because of open3D, this talks specifically of 3.13 when compiling so I have high hopes.

(There is a comfy easy-install version but I would like to avoid having two comfy installs)

[-]

44th--Hokage@reddit (OP)

You can one-shot the install on Opus 4.6 on the API.

[-]

KURD_1_STAN@reddit

I had many many issues with it but it was fixed with getting an older comfyui with python 3.12 because some wheels or something didnt exist for something, i dont remember correctly. Altho the quality is mehh, it isnt bad but nothing to be praised for( i haven't used others so idk how good something is compared to others). Also connecting it to ultrashape fixes a lot of stuff but man does it need vram and is so fing slow

[-]

eposnix@reddit

This guy's comfyui installer got me 90% there. I had a few errors that i called in GPT-5.5 to fix.

Damn. Those subreddits look like they belong to nutjobs who smoke too much weed.

[-]

LetsGoBrandon4256@reddit

I was about to suggest OP try /r/singularity then I saw the sidebar of the sub he moderates.

Luddites, Decels, & Anti-AIs are banned! We're a pro-Singularity, pro-AI alternative to r/singularity, r/futurology, r/artificial and r/technology, as they've become overwhelmed with Technology Decelerationists, Luddites, and Artificial Intelligence opponents.

lmao even

[-]

44th--Hokage@reddit (OP)

People like it. There's a lot of animosity towards AI online and r/accelerate is space created to be a reprieve from the toxicity where people who are excited about the technology can be excited about the technology together.

[-]

TheRealMasonMac@reddit

There is an important difference between excitement and zealotry. When I go to that subreddit and sort by the top posts this month, I see an egregious amount of misinformation, ungrounded speculation, and deification of tech CEOs. This comes across as practically a cult.

[-]

LetsGoBrandon4256@reddit

lmao the replies you are getting.

OP's buddies are here.

[-]

Xilors@reddit

We are gonna need some examples of misinformation/deification, because for now it seems your the one misinforming peoples.

[-]

Hubbardia@reddit

Can you point to some examples? Blatant misinformation? Deification of CEOs?

[-]

44th--Hokage@reddit (OP)

This is what I see when I organize by top of the month:

It doesn't seem much different than any other tech sub on reddit.

[-]

quinn50@reddit

for one this is a LLM focused reddit, /r/StableDiffusion would be better

[-]

TurpentineEnjoyer@reddit

I didn't know about it, I thought Hunyuan3D 2.1 was the best available option because I just go off what ComfyUI has a template for ordered by newest.

So thanks for bringing it to my attention. I swear to god people on this subreddit can get utterly miserable sometimes. God forbid a model could get discussed more than once.

[-]

luckyj@reddit

Sure, but "Microsoft presents" is a bit misleading

[-]

Relative_Bit_7250@reddit

Would have preferred you didn't use the "New Model" tag.

[-]

Appropriate-Bar-8932@reddit

I tested this out last year. Why is this post upvoted? I checked the repo now and it's not updated. I expect they are working on Trellis.3 ?

FinalCap2680@reddit

It is hard to keep up with the releases...

My friend is doing projects to convert speech to image to 3d model to unit game

Honestly, keep me posted, too. That sounds imminently useful.

[-]

Borkato@reddit

Incredible!

[-]

05032-MendicantBias@reddit

I couldn't run it with torch/ROCm

[-]

Monkeylashes@reddit

yeah I'm confused, hasn't this been out for months now?

[-]

FORLLM@reddit

For a lot of us, when models are first released they're nigh unusable. Limited instructions, discussion, howtos, integrations, low vram workarounds, etc. I wish all announcements were months late after there was some ecosystem development already done.

[-]

Innomen@reddit

Plus the demo works nice and fast. (once, before tapping out on usage)

[-]

FinBenton@reddit

Idk, I remember when this was launched, I got it working on comfyUI right away on linux with some random workflow someone on youtube posted first try, played with it a bit but I wasnt super happy with the quality back then, maybe the implementation is better now. It was decent on simple stuff but complicated characters were kinda messy.

[-]

I got Claude to get it to run in ROCm in comfyui https://github.com/kevinkessler/ComfyUI-TRELLIS2 . It was my first experience with Claude Code, and I'll be damned, it works. I running it on a Strix Halo device using this toolbox: https://github.com/kyuz0/amd-strix-halo-comfyui-toolboxes .
