Hi,
The export settings should be saved / remembered during a session. I export quite frequently, and with a mesh with multiple material if I want to export only one material (and reload it in Unreal for example to see some changes), each time I export I need to de-select all for each of the other materials, and then select the values that I want to export from the given material. It becomes tedious very quickly to have to do that each time I want to export.
Thanks,
