Character Management

Built-in targets

Before uploading a custom character, it helps to understand the built-in targets already available in Studio.

• Default: the default humanoid output based on a metahuman-style skeleton
• Unitree G1: a robot-oriented output path for Unitree G1

Custom character workflow

Character Management is currently focused on humanoid FBX assets.

• Only humanoid body structures are supported in the current release
• Custom robot character upload is planned for a future update

Step 1. Upload the source FBX

Upload the character FBX that you want to publish into the AIMoCap library.

Step 2. Edit the A-pose

Adjust the source skeleton into a clean A-pose before binding.

• You can use the default target as a pose reference
• The goal is to align shoulders, arms, spine, hips, and legs into a stable retarget base pose

Step 3. Bind the skeleton mapping

Map the source FBX skeleton to the AIMoCap humanoid target structure.

• hips
• spine chain
• neck chain
• arms and forearms
• hands
• legs and feet

Step 4. Run a retarget test

After pose editing and mapping, run a retarget validation pass.

• AIMoCap creates a test run
• the local retarget runner processes it
• you preview the result before publishing

Step 5. Publish only after the result looks correct

If the retarget result looks correct, publish the character.

If the result is wrong:

• adjust the A-pose
• update the bone mapping
• run the test again

After publishing:

• the character appears in the character library
• the same character becomes selectable as an output target in Video Mocap Studio
