Hi @Warrell
When scanning without color or textures you can do that in complete darkness , MIRACO uses infrared lighting for scanning surface so it don’t needs any other lighting sources .
However if you calibrate MIRACO you need good lighting source because of the RGB camera as well .
The LED lighting is only used when you scanning using color mode , you can always shut down the lighting in the settings or under RGB camera settings so it will not fire any lights at all .
In calibration mode the LED will be turn on automatic to help calibrating the RGB camera together with the Depth camera sensors .
So if you plan to scan in complete darkness you can do it without any supporting lighting .
MIRACO is like a night vision , it sees the surface thanks to infrared projector and depth sensors , infrared light is not visible to human eyes .
