I had a weird thing happen last nite. I have a character I'm working on, who has earrings, a nose ring & an eyebrow ring. Tuesday I rendered as a progress check (all final renders I do in Bryce), and everything was fine. Last nite, I opened the same character, changed only 1 hair dial, and rerendered, and all the jewelry was gone. Back to edit view - there it was, plainly visible. I checked each item's materials, etc. - all normal. New render - no jewelry visible. I finally deleted them all and re-applied new ones from my props library, and it worked ok. I guess the Posergremlins were on duty last nite.
