Hyper3D Rigging
Hyper3D Rigging adds a skeleton and skin weights to an existing 3D character while preserving its geometry, embedded materials and textures. Choose automatic, human, quadruped, bird, dragon, kaiju or custom anatomy, with shell or core skinning. Custom skeletons use a bone hierarchy or an anatomy description. Optionally attach up to 10 compatible stock animations or single-Take FBX clips, and export GLB, FBX or USDZ. A JPG, PNG or WebP reference can guide skeleton selection. Prepare a self-contained mesh facing +Z with +Y up in a right-handed coordinate system; the tool centers and scales it but does not rotate it to face forward. It does not generate textures or remesh the model.

Output Format
GLB
Custom bone hierarchy
JSON array of 1–256 bones with unique name and parent index. One root has parent -1. Optional length is positive; transform is a flat 4×4 matrix. Custom template only; use this or an anatomy description.
Custom FBX clips
JSON array of up to 10 distinct public FBX URLs matching this rig. Each must be at most 25 MiB and contain exactly one Take. Leave stock animations empty; in-place processing is unavailable.
Export format
Default
fbx
Options (3)
GLB, FBX, USDZ
Loop in place
Default
No
For compatible looping stock animations. Non-looping clips are unchanged.
Skeleton description
Describe the anatomy for a Custom skeleton. Leave the bone hierarchy empty.
Skeleton template
Default
auto
Options (7)
Auto, Human, Quadruped, Bird +3 more
Skinning method
Default
shell
Options (2)
Shell — smooth surface weights, Core — precise joint weights
Stock animations
Choose up to 10 compatible clips. Explicit Human, Bird and Quadruped templates support stock animations. Leave custom FBX clips empty.
API request
Submit the generation with POST /api/generate-video, then poll the returned run ID for completion.
