There is a bug in the engine which causes it to render with Scattering on, no matter whether it's enabled or not in the MXS file. There are two ways of dealing with this:

1. When you're already rendering: if you are rendering in maxwell.exe and you see Scattering even though it was disabled when you exported the MXS file, just check, then un-check the Scattering box in maxwell.exe's Edit panel. On the next image update, Scattering will be disabled.
2. Before you render: alter the plugin's default settings such that it sets Scattering = 0.0 for all new scenes. To do this, go to Scene Manager > Output, set Scattering to 0.0, then click Presets > Defaults > Store Current.
