You've convinced me.

I don't worry too much about most shader/materials as I'm primarily concerned with how the satin/organza/chiffon/silk materials look. I love the shimmery sheen of diaphanous items. I've played with those in Iray with less than spectacular results. At least Cycles is open source and information is freely available, unlike Daz's version of Iray.

A point I just thought of is using Cycles shaders made for Poser users. I read the Poser forums daily and took quite an interest in Baggibsbill's work on shaders for nylon and silk stockings (yum!). Is there any reason I can't use them on my imported items?

Thanks again.
