Self-hosted image-to-3D outside the EU/UK/South Korea
What it does
Image or text to a textured, rigged and animated 3D character or prop, exported as GLB, FBX or USDZ with skeleton, skin weights and baked clips. Studio, REST API and MCP server share the same jobs.
Open-weights image-to-3D model with PBR material generation that you can run on your own hardware.
Verdict
For rigged, animated characters straight into Godot, Blender, Unity or Unreal; purchased-credit output is commercial and royalty-free, but there are no free credits.
For devs who can self-host a 3D model generator at no licence cost; the licence excludes the EU, UK and South Korea, and products over 1 million monthly users must request a licence.
