Some programs have difficulty dealing with complex N-gon shapes. The Output: option controls the type of polygon data that will be created, whether to allow creation of N-gons (polygons with more than 3 or 4 sides), or whether to break polygons up to only allow 3 or 4 sided polygons. A denser mesh will be smoother visually but will also contain a lot more data. Move the slider to the right to create a denser mesh with more polygons in it. This will reduce the amount of data generated but will also give a more jagged appearance to the mesh. Move the slider to the left to create a lighter mesh with fewer polygons. Initially the dialog is shown in its compact form: So you'll generally want to make sure surfaces that are next to one another have been joined together into one connected solid object before exporting mesh data.

MoI does extra work to align mesh vertices along shared edges between joined surfaces.

The 'Meshing options' dialog is shown during this process to control different aspects of how the polygon data is generated.Дuring the meshing process the number of generated polygons and points are displayed in the upper-right corner of the main window where command options normally are shown. When saving to a polygon file format, MoI needs to convert from smooth surface data into faceted polygon data.
