"You've made it clear you don't like Carrara". All I said is that I'd been very disapointed by Carrara 4, but that true SSS would have made me upgrade immediately. All I've seen until now looks like basic absorbtion, but I'll be glad to be proved wrong. I don't really care about physical accuracy. All I care for is image quality. And again, (sorry to insist), I have seen no example of SSS in Carrara 5 to date (only basic absorbtion).
