Trellis2
Officially listedHigh-fidelity open-source image-to-3D model generator.
Trellis2
Trellis2 is an AI tool representing the cutting edge of open-source 3D generation, powered by Microsoft Research's underlying architecture. It converts 2D images into high-fidelity 3D models with complete PBR materials in a very short time, making it an efficiency weapon for 3D creators and indie developers.
Core Capabilities
- Rapid image-to-3D: Converts 2D images (JPG, PNG, and more) into high-quality 3D assets in 15-60 seconds, dramatically shortening creation cycles.
- All-purpose voxel parsing: Its innovative O-Voxel architecture precisely generates hollow shapes, thin blades, and other complex geometry that traditional AI struggles with.
- Native PBR material generation: Generates complete physical materials in one click — base color, roughness, metalness, and transparency — with extremely high visual fidelity.
- Industry-standard export: Generated models export instantly to mainstream formats like GLB, OBJ, and STL, connecting seamlessly to 3D software and 3D printers.
- Rich open-source ecosystem: Supports local deployment through ComfyUI nodes, giving power users highly controllable node-based workflows.
- Extreme high-resolution rendering: Using sparse compression techniques, it supports up to 1536³ resolution textures and model detail.
Who It's For Extremely well suited to game environment artists, indie developers, and concept designers batch-building background props and static assets; equally fitting for e-commerce 360° product displays and 3D printing enthusiasts who need rapid model generation and validation.
What Sets It Apart Compared with Meshy and Tripo, Trellis2 is currently the open-source "gold standard for high-fidelity geometry." Free of traditional SDF model limitations, it holds absolute dominance in reproducing hard surfaces and irregular structures, plus the genuine advantage of an MIT-licensed open-source ecosystem.
Editor's Take Trellis2 is unquestionably the most worth-trying open-source image-to-3D tool today. Although its mesh topology still needs rework before use in advanced skeletal animation, and local VRAM requirements reach 24GB, for static asset generation, rapid prototype validation, and rendering quality it is a rare productivity weapon. Highly recommended for 3D professionals to add it to their core workflow.

FAQ
Is Trellis2 free?
Trellis2 offers a free open-source version under the MIT license for local deployment. Its cloud platform also provides a free first-generation trial, after which you can choose a $19/month subscription or on-demand credit packs.
What can Trellis2 be used for?
Trellis2 is mainly used to convert a single 2D image into a high-quality 3D model at high speed, widely applicable to game asset building, e-commerce 360° product displays, 3D printing, and rapid concept prototyping.
Can Trellis2's 3D models be used directly for game animation?
Not recommended for complex rigging and animation. Because the automatically generated mesh topology doesn't meet industry animation standards, it usually needs manual retopology before use.
Which model formats does Trellis2 support exporting?
It supports instant export to industry-standard formats like GLB, OBJ, and STL, importing seamlessly into mainstream engines such as Blender, Unity, and Unreal Engine, or going straight to 3D printing.
How does Trellis2 differ from Tripo AI?
Tripo AI emphasizes rapid generation (about 10 seconds) and a built-in game rigging pipeline, while Trellis2 holds a decisive edge in PBR material quality, reproducing complex irregular geometry, and its open-source customization ecosystem.
What hardware does local deployment of Trellis2 require?
Because high-resolution generation consumes enormous VRAM — the official model is genuinely a "VRAM killer" — a high-end GPU with at least 24GB of VRAM (such as an RTX 3090 or 4090) is recommended for the best experience.
