Can I combine a 3D model with a reference image?

Yes. In the 3D Model to Render tool, upload your model and add one or more reference images for the mood, the materials or the setting. Then use Reference strength to decide how closely the render follows the reference, and Shape strength to keep the geometry of your model.

Yes. Your 3D model gives the structure, and a reference image gives the look.

How to do it

  1. Open 3D Model to Render and upload your model (GLB, GLTF, OBJ or STL, up to 100 MB).
  2. Add a reference image in the advanced settings. It can show a mood, a material, a lighting style or a setting.
  3. Write a short description of what you want.
  4. Adjust the sliders and generate.

The sliders that matter

  • Reference strength: how closely the result follows your reference. A higher value follows it more closely.
  • Shape strength: how strongly the geometry of your model is kept. A higher value keeps the shapes closer to the model.
  • Style strength: how strongly the chosen style is applied.

Tip

Use a reference that shows the one thing you want to borrow, such as the light or the material. A reference with too many ideas gives a less clear result.
