Fudge3d vs TRELLIS.2
Fudge3d packages local 3D workflows into a desktop application. TRELLIS.2 is an open model ecosystem intended for users who want to assemble and run the model stack themselves.

The honest case for running the open model
An open release offers things a closed commercial application structurally cannot:
Full control of the model
Open weights can be inspected, fine-tuned and adapted to your own data. Fudge3d is closed source and offers no equivalent.
No licence fee
The weights cost nothing to download. Fudge3d's generation features are a paid subscription, though its viewer is free forever.
Scriptable into any pipeline
If you want generation as a step inside your own code, an open model drops straight in. Fudge3d is an application, not a library.
Unusual geometry
The approach is documented as handling open surfaces, non-manifold geometry and internal structure – cases that trip up pipelines built around clean closed meshes.
Assembly, platform and what surrounds the model
Because both approaches keep the work on your own hardware, the comparison turns on setup cost, supported platforms, and everything the model does not do by itself.
| Dimension | Trellis 2 | Fudge3d |
|---|---|---|
| What it is | An openly released image-to-3D model from Microsoft Research, published for people to run and build on | A commercial desktop application with generation, texturing, remeshing and a viewer in one installer |
| Inputs | A single image. Text-to-3D is not part of the model | A single image or a text prompt |
| Operating system | Documented for Linux; Windows is not a fully tested path | Windows 10/11 and macOS |
| Getting it running | An NVIDIA GPU with roughly 24 GB or more of VRAM, a CUDA toolchain, a Python environment and model weights fetched separately | A standard installer – next, next, done. No Python, no CUDA setup, no command line |
| Interface | Python inference scripts, or a front end you or the community supply | A native GUI with a built-in 3D viewer |
| Texture output | Full PBR materials including base colour, roughness, metallic and opacity | Albedo, normal, metallic and roughness maps for supported UV-mapped meshes |
| Retexturing an existing mesh | The repository includes shape-conditioned texture-generation code that users integrate into their own stack | A packaged AI Texture Generator for supported UV-mapped meshes |
| Remeshing | The repository includes CUDA mesh utilities for post-processing, remeshing, decimation and UV unwrapping | Remeshing and repainting are packaged in the desktop app |
| Modifying the model | Open weights you can inspect, fine-tune and integrate | Not exposed – Fudge3d is closed source |
| Commercial use | The repository is MIT licensed; listed dependencies retain their own terms, which users must review | You own everything you generate on both tiers, commercially, with no attribution |
| Cost | No licence fee for the weights; you supply the GPU and the time | Free viewer forever; generation is a paid subscription |
| Support | A public issue tracker | A commercial product with a company behind it |

Two genuinely different audiences
Run the open model when
You have a Linux machine with a large-VRAM NVIDIA card, you are comfortable with a CUDA and Python toolchain, you want to fine-tune or embed the model, or you would rather invest time than money.
Choose Fudge3d when
You are on Windows or macOS, you want to install once and start working, you need viewing, texturing and remeshing alongside generation, or you are handing the tool to people who should never have to touch a command line.
Common questions
If Trellis 2 is free and open, why pay for Fudge3d?
You are not paying for the ability to generate – you are paying to skip the assembly. Running the open model means a Linux box, a large-VRAM NVIDIA card, a CUDA and Python toolchain, and whatever front end you build, then solving viewing, remeshing and texturing separately. Fudge3d installs like any other desktop application with those already connected. If you want the control and have the setup appetite, the open model is genuinely the better deal.
Do both run locally?
Yes, and that matters: this is not a local-versus-cloud comparison. Both can keep your work entirely on hardware you control. The differences are packaging, operating-system support, what surrounds the model, and how much stands between you and a finished asset.
Can Trellis 2 generate from a text prompt?
No – it is an image-to-3D model, so you need a starting image. Fudge3d generates from either a single image or a text prompt, and also includes an AI image generator for producing a clean reference image when you only have an idea.
What about textures and PBR maps?
TRELLIS.2 documents full PBR materials including base colour, roughness, metallic and opacity. Fudge3d generates albedo, normal, metallic and roughness maps for supported UV-mapped meshes in a packaged desktop workflow.
Can I inspect or fine-tune the model inside Fudge3d?
No. Fudge3d is closed source and does not expose its weights. If inspecting, fine-tuning or embedding a model in your own code matters, an open-weight release is the right tool and Fudge3d is not.
Skip the toolchain. Keep the local generation.
