Meshy Rigging

Meshy Rigging is a Meshy route built for automatic character rigging. It turns a compatible humanoid mesh into a rigged asset, optionally accompanied by animation, giving creators a focused endpoint instead of forcing one generic workflow across materially different production tasks. The route belongs to a family known for production-oriented 3D creation, editable assets, and fast iteration, so it is best evaluated as a creative system for intentional shots and assets rather than as a one-click novelty generator.

Use this endpoint when the input contract and deliverable match that job exactly. Its documented controls include model_url (URL of a 3D model in GLB format to rig. Can be any publicly accessible URL — works with models generated by Hunyuan, Trellis, Meshy, or any other 3D generation tool. The model must be a humanoid character with clearly defined limbs); height_meters (Approximate height of the character in meters); enable_animation (Apply an animation preset to the rigged model); animation_action_id (Animation preset ID from Meshy's library. Only used when enable_animation is true; in that case it must be in [0, 696] (0 is the "Idle" preset) and is otherwise rejected with a 422. See https://docs.meshy.ai/en/api/animation-library for available action IDs). Together, these controls help teams plan predictable iterations, compare outputs under stable settings, and connect generation to game, product, visualization, and spatial-content pipelines without hiding the operational choices that shape the result.

Highlights

• Purpose-built Automatic character rigging. The route accepts a compatible humanoid mesh and produces a rigged asset, optionally accompanied by animation; its interface is scoped to that transformation, keeping source assets and creative intent explicit.
• Creative direction. Prompts can describe subject behavior, composition, camera intent, lighting, material, atmosphere, and temporal progression so the result is driven by a shot plan rather than isolated keywords.
• Route-specific control. The request exposes model_url (URL of a 3D model in GLB format to rig. Can be any publicly accessible URL — works with models generated by Hunyuan, Trellis, Meshy, or any other 3D generation tool. The model must be a humanoid character with clearly defined limbs); height_meters (Approximate height of the character in meters); enable_animation (Apply an animation preset to the rigged model); animation_action_id (Animation preset ID from Meshy's library. Only used when enable_animation is true; in that case it must be in [0, 696] (0 is the "Idle" preset) and is otherwise rejected with a 422. See https://docs.meshy.ai/en/api/animation-library for available action IDs), allowing the same concept to be tested systematically while preserving a repeatable production setup.
• Pipeline-ready output. The generated 3D asset is returned through the documented asynchronous output contract, which suits review queues, batch iteration, and downstream automation. Artists can inspect topology, UVs, textures, normals, roughness, metallic response, skeletal readiness, polygon budgets, and interchange suitability before approving a build.

When to Use

Prompt Guide

Start with the desired result, then describe the source relationship, subject action, composition or camera behavior, lighting, style, and timing. For automatic character rigging, state what must remain stable as clearly as what should change. Use only fields exposed by the schema; the example below is structurally valid for this route.

{
  "model_url": "https://static.sandbase.ai/examples/meshy/rigging/input_model_url_0.glb",
  "height_meters": 1.7,
  "enable_animation": false,
  "animation_action_id": 92
}
