I have rendered the figure using the default modes in both firefly and in superfly in poser 11 and poser 13.

Sorry! The renders are sharp in Poser 11 and in 13 THE SUPERFLY rendering produces unsharp images. I have no doubt now there is a critical issue with Poer 13 Supefly renderer. I sell products on Renderosity and the creators of Poser 13 need to fix this!
