Pixal3D is TencentARC's image-to-3D generation model built on the Trellis 2 architecture. It offers fine-grained control over a 3-stage generation pipeline (structure, shape, texture), allowing technically experienced users to tune guidance strengths, sampling steps, mesh resolution, and vertex counts for each stage independently.

How do I use Pixal3D online?

Go to 3D AI Studio, select Pixal3D as your model, upload a reference image, configure your generation settings (texture resolution, mesh resolution, guidance strengths), and click generate. Preview the result in the 3D viewer, then download in your preferred format. No installation or coding required.

Is Pixal3D free to use?

New users receive free credits to try Pixal3D on 3D AI Studio. Each generation costs 20 to 40 credits depending on texture resolution: 1024x1024 costs 20 credits, 2048x2048 costs 30 credits, and 4096x4096 costs 40 credits. No subscriptions or commitments required.

How long does Pixal3D take to generate a 3D model?

Pixal3D typically takes 4 to 5 minutes to generate a 3D model. Generation time varies depending on the selected mesh resolution, texture resolution, and number of sampling steps configured for each pipeline stage.

Can I use Pixal3D models commercially?

Yes. The 3D models you generate with Pixal3D on 3D AI Studio belong to you. You are free to use them in commercial projects, games, products, marketing materials, or any other purpose.

What file formats does Pixal3D support?

Pixal3D outputs GLB format. You can convert your models to OBJ, FBX, STL, or USDZ using the built-in conversion tools on 3D AI Studio. All formats are compatible with Blender, Unity, Unreal Engine, and other 3D software.

Who is Pixal3D recommended for?

Pixal3D is recommended for technically experienced users who want granular control over 3D generation parameters. It is an experimental model that may produce mesh artifacts in some cases. For most users looking for reliable, production-quality results, we recommend Hunyuan 3.1 Pro or Prism 3.1 instead.

Fine-Grained Control Over 3D Generation with Pixal3D

Generate 3D models from images with independent control over structure, shape, and texture stages. Configure mesh resolution, vertex counts, guidance strengths, and sampling steps for each pipeline stage.

What makes Pixal3D different

Full control over every stage of the 3D generation pipeline

3-Stage Pipeline Control

Independently adjust guidance strengths for structure, shape, and texture stages. Fine-tune how strongly each stage follows your input image.

Adjustable Texture Resolution

Choose between 1024x1024, 2048x2048, or 4096x4096 texture resolution. Higher resolution costs more credits but produces sharper surface detail.

High Vertex Counts

Generate models with up to 2,000,000 vertices. Control the maximum vertex count to balance detail against file size and performance.

Mesh Resolution Options

Select mesh resolution of 1024 or 1536. Higher mesh resolution captures finer geometric details in the generated model.

Reproducible Seeds

Set a specific seed value to reproduce the same generation result. Useful for iterating on settings while keeping the base output consistent.

Configurable Remeshing

Control whether and how the output mesh is remeshed. Adjust target polygon counts and topology optimization for your specific use case.

How to use Pixal3D on 3D AI Studio

From image to downloadable 3D model in four steps

01

Upload Image

Upload a reference image of the object you want to convert to 3D. Clear, well-lit photos work best.

02

Configure Settings

Set texture resolution, mesh resolution, vertex count, and guidance strengths for structure, shape, and texture stages.

03

Generate

Pixal3D processes your image through its 3-stage pipeline. Generation takes 4 to 5 minutes depending on your settings.

04

Export

Download in GLB format, or convert to OBJ, FBX, STL, or USDZ. Ready for Blender, Unity, Unreal, or 3D printing.

Key parameters you control

Pixal3D exposes the full generation pipeline for advanced configuration

Generation Pipeline

Structure Guidance

Controls how closely the structure stage follows the input image. Higher values produce geometry closer to your reference.

Shape Guidance

Adjusts the shape refinement stage. Fine-tune how the model interprets surface details and proportions.

Texture Guidance

Sets the strength of texture generation guidance. Higher values produce textures more faithful to the input colors and patterns.

Sampling Steps

Configure the number of diffusion steps for each stage. More steps generally improve quality at the cost of generation time.

Output Configuration

Texture Resolution

1024 / 2048 / 4096

Higher resolution textures capture finer surface detail. Cost scales with resolution: 20, 30, or 40 credits.

Mesh Resolution

1024 / 1536

Controls the density of the generated mesh. Higher values capture finer geometric features.

Max Vertices

Up to 2,000,000

Set the upper limit on vertex count. Balance between geometric detail and file size.

Seed

Any integer

Set a fixed seed for reproducible results. Same image and settings with the same seed produce the same output.

Supported export formats
