Hyper3D Rodin: AI-Generated 3D Models in MCP for Blender

Generate custom 3D models from text prompts or reference images using Hyper3D Rodin inside MCP for Blender, then import them directly into your scene.

Hyper3D Rodin generates high-quality 3D models from a text description or a reference image. When your scene needs a custom prop that does not exist in any asset library, Rodin can create it from scratch and import it directly into Blender.

Setup

Before you can generate models, configure your API key.

  1. Get an API key at hyper3d.ai.

  2. In Blender, press N in the 3D viewport and open the MCP for Blender tab.

  3. Tick Hyper3D Rodin.

  4. Paste your API key into the field, or click the free trial button to use the shared trial key.

To store the key permanently, go to Edit → Preferences → Add-ons → MCP for Blender and enter it in the Hyper3D API Key field. Alternatively, set the environment variable BLENDERMCP_HYPER3D_API_KEY before starting Blender. You can also use a fal.ai API key if you have one: switch Mode in the Hyper3D Rodin panel from hyper3d.ai to fal.ai.

Generation Workflow

Your AI generates models with generate_3d, which submits the job, waits for it, and imports the result in one call. If generation takes longer than the wait time, it returns a job handle and the AI calls it again to keep waiting.

generate_3d(prompt="garden gnome", provider="hyper3d")

With Rodin you can also pass bbox_condition=[length, width, height] to control the model's proportions.

After import, always check the world bounding box and adjust location, scale, and rotation. AI-generated models may not align perfectly with your scene units or orientation.

Best For

Use Hyper3D Rodin when you need custom or unique items that are not available in Poly Haven, Sketchfab, or Poly Pizza. It works best for single objects, not whole scenes.

Custom Props

Unique objects that do not exist in any asset library, like a specific character or branded item.

Single Objects

Individual models with clear boundaries. Avoid using Rodin for ground planes or environment elements.

Limitations

Keep these constraints in mind when planning your prompts:

  • Free trial keys have a daily generation limit.
  • Rodin is designed for single-object generation. Do not try to generate a whole scene in one shot.
  • Results may require cleanup, remeshing, or manual adjustment after import.
