How to Use Tripo3D H3.1 Text to 3D

  1. Write a detailed prompt: Up to 1,024 characters. Use negative_prompt to exclude unwanted features.

  2. Pick texture quality: standard is the default; detailed produces higher-resolution maps for an additional fee.

  3. Pick geometry quality: detailed adds finer surface detail (+$0.20).

  4. Optional add-ons: Enable quad for quad-topology mesh (+$0.05), pbr for physically-based materials, or auto_size for automatic scaling.

  5. Submit: Poll until the prediction returns a .glb URL.

Common Questions

Frequently asked

When should I use detailed geometry?

When you need fine surface details preserved (e.g., engravings, fabric folds). Costs an extra $0.20 per generation.

What's quad topology good for?

Quad meshes are easier to rig, subdivide, and edit by hand. Recommended for character work.

How does pricing tier work?

Standard textures: $0.20. Detailed textures: $0.30. Add-ons stack: detailed geometry +$0.20, quad mesh +$0.05.
