Generate a 3D model from a text prompt

Write one sentence about the object you want. The generator returns a textured 3D model with a thumbnail and model files in several formats, ready to open in the SimplexGen editor.

This tool runs on GPU capacity. You must be signed in, each run is metered in credits against your account, and the API needs a paid plan with an API key. Anonymous visitors cannot start a job.

How it works

  1. Describe a single object: material, shape and style.
  2. Toggle PBR materials, or ask for geometry only.
  3. Open the result in the editor, simplify it and export it.

Questions

How do I write a good 3D prompt?

Describe one object, its materials and its silhouette. Skip scenes and backgrounds.

Can I start from an image instead?

Yes. Use the image to 3D generator, or make a reference image first with the image generator.

How is it billed?

Each run uses generation credits shown on the tool page. API calls require a paid plan and an API key.
