To output materials without antialiasing, use the standard [Render Output] without using Render Elements. If you uncheck [Render Scene] dialog > [Render] tab > [Antialiasing], Render Elements are not output correctly due to the way 3ds Max's [Scanline Renderer] works.
Please note that Render Elements cannot be output when [Antialiasing] is off regardless of whether Pencil+ is used or not.
