Lighting is a key component of how MARSO identifies the material properties of a 3D-scanned object. MARSO is designed to work with easily accessible lighting hardware, yet there are still key considerations to be made.
A single light works best when placed close to the lens, however, in scenarios where this is not possible, we suggest using multiple lights sequenced one light at a time.
Light Type
For best results, we recommend using as small of a light as possible. Sometimes this can be achieved by removing any diffusion or reflectors attached to an existing light fixture to expose just the bulb.

Light Size
The size of the light source plays a key role in M-XR’s ability to identify roughness. By using a relatively small light source, glossy surfaces can be predicted as the reflections are sharper. It is worth noting that the size of the light source is however relative to how close the light is to the subject.
The example below illustrates this effect when the same-sized light is used for near / far scans
Smaller Light = Better Materials
