Ideal Bone Distribution and TPose

Bone Mapping

Required Bones

The Hips (pelvis) bone is the only bone that must be mapped, as this bone is responsible for translating the character.
The rest of the bones are optional, but it is highly recommended to have the entire bone structure, as missing bones can negatively impact the animation result.

Bone Naming Convention

Any bone naming convention can be mapped using the add-on.

Supported Bone Naming Conventions

Rigs that follow one of the supported naming conventions can be automatically mapped in the add-on. Namespaces Prefix to an object or bone name separated by the : symbol.
Example:
MyCharacter:Hips
MyCharacter:Spine
are supported.

Supported bone naming conventions:

Autodesk Flow Studio
Mixamo
Human IK
Quick Rig
Unreal Engine
Character Creator 4
Daz 3D
BlenRig
Rigify
Auto Rig Pro

Given that these packages are beyond our direct control, we cannot guarantee their compatibility in all scenarios or instances. These packages may not have seamless compatibility, so it remains crucial to adhere to all requirements outlined in the documentation.

In the case of characters that are using rigging tools that generate both FK and IK systems, please make sure to set the rigs into FK mode before uploading the character.

Rigging Tools

Character Creator 4 - Blender

When bringing CC4 characters into Blender, double-check the scale of the character and the length of the Head bone. As the characters often have a scale of 0.01, and the Head bone length is very small, this can cause the Head bone to disappear once the character's transforms are applied. Head bone length should be modified in the software of your choice by making it longer. Additionally, an end bone can be added.

Rigify - Blender - Missing Spine Bone

When mapping Rigify rigs, the Auto Assign Bones feature will leave out the Spine bone mapping. The ideal bone for this mapping would be the spine_fk bone but this bone is not transferring animations up the spine bone chain. Instead, this bone rotates the lower part of the torso along with the legs.

Rigify - Blender - Scale Not Functional

The ideal bone for translating the character, in the Rigify rig, is the "torso" bone.
However, this bone can not scale the entire character. For this reason, we recommend running Rigify characters in Live Action Advanced project type with Scale turned off in Advanced Retargeting settings.
