Hi Michael,

From what i understand, at this point any information in a 3dm-file that is not supported by Moi is lost after a save, e.g. lights, layers etc. Would it be possible to retain that information. I image this may be more difficult for attributes of objects like layers, but easier for objects like ligths.
