Rigged characters, without the rigging.
A prompt, an image, or a mesh you already own — out comes a skeleton with solved skinning weights, as standard glTF or FBX.
A skeleton that fits the shape it is given
Bones are placed from the geometry itself, not snapped to a fixed humanoid template. That is why the same pipeline handles a dwarf, a robot dog and a cartoon dragon without per-category setup.
- Joints land inside the volume, not on the surface
- Limb chains follow the mesh, however many there are
- Weights are fitted per vertex, not painted by hand

Drag to reveal the generated skeleton
One model, every body plan
Humanoids, quadrupeds and creatures go through the same pipeline.

Three choices and a button
Pick a source, pick a poly budget, run it. The whole interface fits on one screen.
Source in, rigged asset out
- 01
Bring a source
Type a description, drop in concept art, or upload geometry you already modelled.
- 02
Geometry is built
Text and images become a watertight textured mesh at the density you choose.
- 03
The skeleton is solved
Bones are predicted from the shape, then skinning weights are fitted per vertex.
- 04
Export and animate
Download glTF or FBX and open it anywhere. Nothing is locked to this account.
What lands in your downloads
Your geometry, untouched
Vertices and faces return exactly as they went in. Nothing is decimated or re-topologised behind your back.
A bone hierarchy
A topologically valid skeleton with named joints and real parent-child relationships — not a flat list of empties.
Per-vertex skinning weights
Every vertex bound to the bones that move it, so the mesh deforms instead of shearing at the joints.
A standard container
glTF or FBX. No plugin, no proprietary wrapper, no account needed to open the file in two years.
Drops into what you already use
Standard formats mean no importer to install and no SDK to learn.
import bpy
# The export is plain glTF — no add-on required.
bpy.ops.import_scene.gltf(filepath="character.glb")
armature = next(o for o in bpy.context.scene.objects if o.type == "ARMATURE")
mesh = next(o for o in armature.children if o.type == "MESH")
print(len(armature.data.bones), "bones")
print(mesh.vertex_groups.keys()) # one group per deforming boneAgainst doing it by hand
An automated rig is a strong starting point, not a substitute for a technical animator on a hero character. Expect to hand-correct weights around problem joints.
Choose the poly budget
Half a million faces looks great and animates badly. Pick for the job.
Built for people shipping on a deadline
Indie game teams
You can model. You cannot spend three days weight-painting every NPC. Rig the background cast in an afternoon and hand-finish only the hero.
Previz and animatics
Blocking a shot does not need a production rig. Get something posable in minutes, decide the camera, then commit to real assets.
XR and simulation
Bulk-rig scanned or generated props and characters so they deform properly instead of sliding around as rigid bodies.

Credits, not subscriptions
Buy what you need. You are only charged for runs that finish.
Rigging runs on a GPU that spins up on demand — a few minutes per asset, not seconds. Close the tab if you like; results land in your library.
Before you sign up
What file formats can I upload for rigging?
GLB, OBJ, FBX and VRM meshes can be uploaded and rigged directly.
What do I get back?
A standard glTF or FBX file containing the original geometry, the predicted bone hierarchy and per-vertex skinning weights. There is no proprietary wrapper, so it opens in Blender, Unity, Unreal and Godot.
How long does rigging take?
Rigging runs on a large GPU that starts on demand, so expect roughly four to eight minutes per asset. You can close the tab; results are saved to your library.
How many polygons should my character have?
Around 40,000 faces is recommended for anything you plan to animate. Denser meshes look better in stills but are slower to rig and heavier in a game engine.
Is there a subscription?
No. Pantheon Rigs uses credits that you buy as needed, and you are only charged for runs that complete.
Can I use the results commercially?
Yes. You own the meshes and rigs produced for you and may use them in commercial projects. You are responsible for holding the rights to anything you upload as a source.
What happens if a run fails?
Failed and cancelled runs are not charged. If a two-stage run fails at the rigging step, the generated mesh is still saved to your library so the credits you already spent are not lost.
Does it produce animation as well?
No. You get a rigged character — skeleton and skinning weights — not motion. Animate it yourself, or drive it with any motion library your engine already uses.
