I too have lost presets due to them becomming corrupt. I always keep a backup of my preset folder. If all of the ferns did this, then I would know that I screwed up, but this is only happening to one out of ten ferns. For the crested wood fern only I can import it, set the texture, render, etc. The only things I can't do is save the Bryce file (it only has the fern in it) or save it to the presets. I sent an e-mail to RTDNA to ask them about this. If I get an answer I'll post a message. Thanks! Peggy
