Model in Octane is 600k+ polys. Original ZBrush model is 130ish million. What can I say, it was just a test to see how much detail I could fit in using the HD sculpting ability, and now that ZBrush will actually export that data in a useful form, it's kind of fun to render.
Since it was a learning exercise in ZBrush, and an old one at that, there are a lot of errors. Some of which contribute to the very, very sparkly nature of this image. I've noticed that bump and normal maps on glossy surfaces produce a ton of fireflies at very contrasty normal boundaries. Seems to be a glancing angle thing. And since this model has a bunch of goofy-dumb sculpting on it that needs smoothing out and fixing, all those areas show up in neon in Octane.
.. Edited to add to the subject that the image contains nudity or nudity-like substances.
