3D Part-Based Generation

Key benefits

• Automatic mesh segmentation

  The models analyze geometry and separate a complex model into logically distinct sub-meshes, no manual cutting required.

• Multi-part output in one step

  PartCrafter transforms a single RGB image into 2 to 16 separate, semantically meaningful 3D meshes simultaneously.

• Animation-ready components

  Each segmented part is output as its own clean mesh, ready for independent rigging, keyframing, or procedural animation.

• Modular asset design

  Break down characters, vehicles, and props into interchangeable components for modular game design and variant creation.

• No manual intervention

  Both tools identify and separate components automatically, no segmentation masks or manual selection needed.

• Compatible with full editing pipeline

  Segmented parts feed directly into Meshy Remesh, Retexture, and Rigging for a complete post-processing workflow.

How it works

1. 1

   Upload your model or image

   Provide a 3D mesh for Hunyuan 3D Part, or a single RGB image for PartCrafter to generate and segment simultaneously.

2. 2

   Run part segmentation

   The AI identifies distinct structural components and outputs each as a separate, named sub-mesh in a single pass.

3. 3

   Edit and export independently

   Work on each part individually, retexture, remesh, or rig specific components, then export as GLB or OBJ for your pipeline.

Use cases

• Mechanical animation

  Separate wheels, doors, and panels on vehicles for independent movement and rigging.

• Character modular design

  Isolate heads, limbs, and accessories on characters for swappable part systems in games.

• Prop breakdown for VFX

  Segment complex objects into parts for destruction simulations or physics-based animation.

• Modular environment assets

  Break architectural or structural models into reusable, combinable components.

• Rapid prototyping

  Quickly isolate and test individual parts of a generated model without remodeling the full asset.

• Creature & character rigging prep

  Isolate individual limbs and body segments on creatures before passing them to Meshy Rigging, giving animators clean, independently controllable parts to work with.
