Hunyuan 3D 3.1 takes a single photo or a text description and outputs a fully textured 3D model with accurate geometry, skipping the hours typically spent in modeling software. Designers, product teams, and hobbyists get a deployable mesh without touching a single vertex manually. The model offers two generation modes: Normal produces a textured model with color and surface detail maps, while Geometry outputs a clean white mesh ideal as a base for manual texturing. Enabling PBR materials means the resulting textures respond correctly to light in any rendering engine. You can also set the face count to match your target, from a lightweight mesh for a web viewer to a dense model for print production. Drop the output directly into a product visualization pipeline, a game asset library, or a 3D printing workflow without extra conversion steps. The files work in standard 3D software and real-time engines out of the box. Set your input, pick your mode, and have a usable 3D asset ready in minutes.
Hunyuan 3D 3.1 takes a photo or a text description and turns it into a fully textured 3D model with dense geometry and surface detail. For anyone who has ever needed a 3D asset but does not have time to model it by hand, this is the direct solution. A product shot, a character concept, a simple written description: any of these becomes a mesh you can drop into a render or a scene. Picasso IA makes the whole process available in a browser, with no software installation. The output geometry holds up at close range, and the textures are accurate enough for professional use cases.
Do I need programming skills or technical knowledge to use this? No, just open Hunyuan 3D 3.1 on Picasso IA, adjust the settings you want, and hit generate.
Is it free to try? Yes, you can run Hunyuan 3D 3.1 without an upfront payment. The platform's credit policy covers how many generations are included at each tier.
How long does it take to get results? Most generations complete within a few minutes. Higher face counts and PBR material generation add some time, but standard settings are quick enough for rapid iteration.
What output formats does the model produce? The model returns a 3D file compatible with standard 3D applications. The exact format is shown on the results panel after generation finishes.
What kind of image works best as input? A single object centered in the frame, occupying more than half of it, against a plain or white background. Avoid images with text, multiple objects, or cluttered scenes. JPG, PNG, JPEG, and WebP are all accepted, up to 6MB and between 128 and 5000 pixels per side.
What is PBR and when should I use it? PBR stands for Physically Based Rendering. It encodes how a surface reflects and absorbs light, so the material looks correct under different lighting conditions in compatible software. Enable it when your pipeline uses a PBR-capable engine; skip it for geometry-only workflows or quick previews.
What if the result does not match what I had in mind? Refine your prompt with more specific details, or swap in a cleaner photo with a simpler background. Adjusting the face count can also change how much surface detail the model captures. Small input changes often produce meaningfully different outputs.
Everything this model can do for you
Accept a photo or a written description as the starting point for 3D generation.
Enable Physically Based Rendering to get textures that respond correctly to light in any rendering engine.
Generate a clean white mesh without textures for cases where manual texturing is preferred.
Set polygon density from lightweight web-ready meshes to dense models suited for print or film.
Normal mode produces color and surface detail maps alongside the mesh in a single pass.
Go from input to a downloadable 3D file entirely online, with no local tools required.
Supports JPG, PNG, JPEG, and WebP files up to 6MB and 5000px per side.
