Rig variability
FBX avatars can differ in bone names, hierarchy, rest pose, scale, and mesh organization, so a preparation step is safer than blind retargeting.
CUSTOM AVATAR
FBX avatar mocap workflow
Upload, bind, test, and publish FBX avatars so AIMoCap video mocap jobs can reuse them as targets.
For teams searching for mocap on their own FBX avatar.
Short answer
FBX avatar mocap is a two-stage workflow: prepare the FBX character as a reliable AIMoCap target, then run video mocap jobs against that published target.
When to use AIMoCap
Use AIMoCap when you already have an FBX character and need a browser workflow for upload, A-pose review, skeleton binding, retarget testing, publish, and repeated mocap jobs.
When not to use AIMoCap
Do not treat an arbitrary FBX file as automatically mocap-ready. Rig structure, rest pose, skeleton mapping, and test results still need review before production reuse.
Users searching for FBX avatar mocap usually need more than a video-to-FBX export. They want source motion to appear on a specific character that their team already owns.
AIMoCap handles that as a reusable target workflow: upload the FBX avatar, check the pose, bind the skeleton, run a retarget test, and publish only after the result is usable.
This separation matters because the avatar asset and the source video fail in different ways. A clean video cannot fix a poorly prepared rig, and a good rig still needs readable motion input.
FBX avatar mocap facts
- FBX avatar mocap depends on both source-video quality and avatar rig preparation.
- Upload alone is not the same as a reusable target; binding and retarget testing are the quality gate.
- Published avatars are intended for repeated Studio job selection.
- A-pose review helps reduce pose-offset surprises before retarget testing.
- Custom avatar output is separate from Default FBX animation output.
- Unitree G1 robot output is a different target class and should not be mixed with character retargeting.
- Teams should inspect the retarget result before using the avatar in production animation cleanup.
Why FBX avatar mocap needs preparation
Use these facts to decide whether this workflow matches your output, integration, and cleanup needs.
Reusable target value
The setup cost pays off when the same published character is used across many mocap jobs instead of being fixed from scratch each time.
Clear workflow boundary
AIMoCap separates character setup from video processing, which makes it easier to diagnose whether a problem comes from the avatar or from the source clip.
FBX avatar mocap workflow
01
Prepare the FBX character
Create the character profile, upload the FBX asset, and confirm that the uploaded model is the character you intend to reuse.
02
Review pose and skeleton mapping
Use A-pose preparation and binding review to align the avatar with AIMoCap's retargeting expectations before any mocap job depends on it.
03
Run a retarget test
Test the character with sample motion so arm, leg, spine, and root behavior can be inspected before the avatar is published.
04
Publish for repeated video jobs
After approval, publish the avatar so future Studio mocap jobs can select the same target without repeating setup.
Common questions
Can I use any FBX avatar for mocap?
Not automatically. The avatar should be uploaded, pose-checked, skeleton-bound, retarget-tested, and published before it becomes a reliable reusable target.
Is FBX avatar mocap the same as video to FBX?
No. Video to FBX focuses on downloadable animation output. FBX avatar mocap focuses on driving a specific prepared character target.
Why does AIMoCap require a retarget test?
The test helps catch skeleton mapping, pose offset, and motion quality issues before the avatar is reused in future mocap jobs.
Can a published avatar be reused?
Yes. Publishing is the handoff that makes the tested avatar selectable for repeated Studio mocap jobs.
Does this replace animation cleanup?
No. It creates a target-aware mocap result, but production teams should still inspect and clean up animation in their downstream tools.
