Hi Luca, also you wrote:

The second screenshot that you are showing there is simply the Max dialog for OBJ export settings.

There are some similar settings you can set for MoI's OBJ export as well, under Options > Import/Export OBJ options. The option in MoI for "Orientation" is equivalent to the "Flip YZ axis" setting in your screenshot there, and there are also settings in MoI there that are equivalent of the scale factor that you show and also disabling writing material definitions.

There are also some other settings in MoI which you can edit in the moi.ini file for some other options, like the number of decimal places to use in the numeric formatting, and whether to disable writing texture coordinates. These are not shown directly in the options dialog because they are not particularly useful for typical use of the OBJ export.

So those various option actually do exist in MoI, but in general with MoI I try to avoid slamming these kinds of dialogs that are heavily populated with rarely used things right in your face on every single OBJ export...
