You are talking about C4 and not Amapi 7, right? I only ask because if you change the two names around then those results would be expected. From Brycetechs (excellent) Amapi 7 tut: "*Amapi 7 does not support as many export formats as earlier versions did. It no longer directly exports to "Lightwave" or "Max". With the intention of the program to be a "modeler" whose models are rendered elsewhere, the loss of these direct export formats may leave a few people confused. However, It does support obj and 3ds, and most rendering programs do support these format."
