Rigging in Unity

Rigging and Skinning Tools for Unity Workflows

Build bone hierarchies, paint weights, transfer skinning work, and prepare meshes for handoff into the Unity Animator — without leaving the editor.

Rigging Usually Means Leaving Unity

Building a skeleton in one app and testing it in Unity means the rig you set up and the animation you preview are always a round trip apart.

What the round-trip rig costs

  • Bone hierarchies are built in a separate application, then exported and hoped to import cleanly.
  • Skin weights look fine in the other tool but deform differently once they reach Unity.
  • Every weight tweak means another export, re-import, and re-test cycle.
  • Preparing a mesh for the Unity Animator becomes a checklist across two toolsets.

What rigging inside Unity changes

  • Build and adjust the bone hierarchy directly on the mesh in the Unity Editor.
  • Paint and transfer skin weights and see deformation in the same environment.
  • Iterate on the rig in place, so adjustments and testing stay close together.
  • Prepare meshes for the Unity Animator without a separate application in the loop.

Build the Rig, Then Hand It to the Animator

A rigging and skinning flow that stays inside Unity, from skeleton to Animator handoff.

STEP 01

Build the skeleton

Lay out a structured bone hierarchy on the mesh.

STEP 02

Skin the mesh

Bind the mesh to the skeleton and set up vertex influence.

STEP 03

Paint & transfer weights

Refine deformation and transfer weights to speed up similar meshes.

STEP 04

Hand to the Animator

Prepare the rigged mesh for the Unity Animator workflow.

Rigging and Skinning, Inside Unity

Bone hierarchy control, skeletal editing, weight painting and transfer, and a path into the Unity Animator.

Efficient Skeletal Edit & Build Tools

Add, position, and edit bones with build tools in the editor.

Expressive Weight Painting & Transfer

Paint skin weights for smoother deformation and transfer weights between similar meshes.

Integration with the Unity Animator

Prepare rigged meshes for the Unity Animator workflow.

Why Rig Inside Unity

Rig on the Mesh in Context

Build and adjust the skeleton directly on the model in Unity.

Fine-Tune Deformation

Weight painting shapes how the mesh bends and follows each bone.

Reuse Work with Weight Transfer

Carry rigging work forward between similar meshes.

Straight into the Animator

Prepare rigged meshes for the Unity Animator in one project.

Where the Rigging Toolkit Helps

Character & creature rigs

Build bone hierarchies and skin characters and creatures.

Preparing meshes for the Animator

Set up rigged meshes for animation workflows.

Adjusting imported & AI-generated meshes

Adapt meshes that need project-specific rig work.

Iterating on deformation

Refine how a mesh bends and responds to the skeleton.

Frequently Asked Questions

Can I build rigs inside Unity?

Yes. UModeler X provides rigging and skinning tools for building and adjusting rigs inside the Unity Editor.

Does rigging happen automatically?

No. Rigging may require project-specific review or refinement.

Can I prepare assets for the Unity Animator?

Yes. The workflow is designed to help prepare rigged meshes for the Unity Animator.
