Many buyers of the new Wooly Mammoth (available at Renderosity) will find Poser totally crashes when making either SuperFly or Firefly renders. The main culprit is the size of the many skin materials — 8192px and 20Mb for one Skin_Normal.jpg for instance. And the same size again for just the Mouth Normal map, too. There are 15 other skin materials of comparable size to load. Groan.
My solution was manually resizing the 15 materials found in the “dull” folder, which is where the various skins materials live. Saving Skin_Normal.jpg at 2048px and 65% JPG compression resulted in a mere 465kb normal map (down from 20Mb), for instance. The others were similarly resized. With these lightweight skin materials loaded to the Mammoth the SuperFly rendering was then fine, and the fur looks much as it does in the Store preview — very nice indeed and with no loss I could detect. What can be seen of the skin still has nice detailing. A FireFly render still crashed Poser, though.
So… it doesn’t toon well (which is to be expected), Firefly may be iffy for you, but SuperFly is OK and most people will want to manually reduce the texture sizes down from 8k.
