This article is for V2 and V1 3D scanners.
Geometry Settings can be found at the top of the Scan Setup sidebar. The slider controls the camera’s exposure, making the laser line(s) visible for capturing an object. Laser lines will bounce off different colours and object materials differently, influencing how well MFStudio will detect them. Changing the camera’s exposure can make the lasers more, or less, visible.
Here is an example of a noisy laser line with gaps. This will give a poor quality scan.
This picture shows Laser 1 (the reddish-pink line) in +Quickscan. The green overlay shows where MFStudio "sees" the lasers, i.e. where the object is being detected. Adjusting the Geometry Settings slider will change how easy it is for the scanner to see the laser.
The best exposure for your object is where the green overlay is a sharp line, meaning that it doesn’t have a lot of gaps or noise. Noise appears as fuzzy static rather than a straight solid or nearly solid line. The more defined and filled-in the laser line the better the results.
In this photo the gaps are closed. This is a good laser line and will give a good quality scan.

You will notice that dark-colored objects need a bright camera exposure, and light-colored objects need a darker camera exposure for the best laser line detection. When more than one exposure gives good results, choose the lower exposure, as this reduces the capturing of noise points from the scan bed. It will can lower the scanning time in Regular Scan mode.
If your laser line detection is poor at every exposure, it usually means there is too much light in the room. Try blocking light from hitting the scanner.
