This article was prepared with AI assistance based on an analysis of the current Lumina Studio source code, existing Wiki content, and relevant workflows. It has been checked against the current version, but omissions or details that become outdated may remain as the software evolves.

Relief

Relief turns a flat colour model into 2.5D geometry. Colour recipes still control the surface colour; the Relief settings control the height assigned to each region.

What enabling Relief changes

• Structure Mode is forced to Single-sided.
• Cloisonné is disabled because the two geometry paths are mutually exclusive.
• If a palette exists but has no height data, Lumina creates an initial map using the selected luminance direction.
• The old preview and 3MF become stale and must be regenerated.
• Relief is currently unavailable in Vector mode.

Maximum height

The range is 0.08–15 mm in 0.04 mm steps. Changing the maximum rescales existing colour heights proportionally instead of flattening every colour to the same value.

With Material Archive, the minimum also has to contain the current optical stack. Lumina derives a safe lower bound from the material layer count and backing thickness.

Auto Height Mode

Mode	Height source	Result
Darker Higher	Current palette luminance	Darker colours receive more height
Lighter Higher	Current palette luminance	Lighter colours receive more height
Use Heightmap	A separately uploaded image	Image luminance becomes continuous height

Changing either luminance mode recalculates the map immediately. Use Heightmap accepts PNG, JPEG, BMP, or TIFF after a normal preview has created the active session.

Start with a shallow value, inspect the 3D result, then increase it gradually. Always inspect the highest areas, thin edges, and backing again in the slicer.
