What each setting does

Mode

Photo relief: Turn image brightness into raised depth. Logo / outline extrude: Give a high-contrast outline a flat thickness.

Width (mm)

Sets the exported STL’s physical width. The preview auto-fits, so its on-screen size may look unchanged.

Relief height (mm)

Sets the height variation above the base. Larger values create a deeper relief.

Mesh quality

Standard: Best for fast previews, simple shapes, and smaller STL files. Detailed: Best for everyday photo reliefs and most 3D prints, balancing detail and browser performance. Ultra-detailed: For small text, precise heightmaps, and rich textures; creates many triangles and may make the browser unresponsive.

Base thickness (mm)

Adds a solid backing below a photo relief so the result is a closed printable solid.

Threshold

Controls which pixels are included in silhouette mode. Higher values keep only lighter areas; lower values also include darker areas.

Invert brightness

Swaps light and dark height mapping so dark pixels become raised instead of recessed.

Smooth image sampling

Softens pixel noise and abrupt height changes before the mesh is built.
