Character Management

Upload a humanoid FBX, edit the A-pose, bind the skeleton mapping, test retargeting, and publish the final character.

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.

Upload a humanoid FBX into Character Management.
Upload the source FBX for the character you want to validate and publish.

Step 2. Edit the A-pose

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

Editing the source character into a clean A-pose.
Edit the uploaded character into a stable retarget base pose.
Referencing the default A-pose while editing the custom character.
Use the default target A-pose as a visual reference when aligning shoulders, arms, spine, hips, and legs.

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
Binding the source skeleton to the AIMoCap humanoid target mapping.
Finish the humanoid bone mapping before creating a test run.

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
Starting a retarget validation test for the bound character.
Start a retarget test after the binding and A-pose look correct.
Reviewing the retarget result before publishing the character.
Review the retarget result carefully before deciding whether to publish.

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
Publishing a validated custom character into the AIMoCap character library.
Publish only after the motion result looks correct in the review step.
