you CAN render dynamic hair in Carrara. i just did a month of very heavy testing of C5P specifically about strand hair imported from Poser. Search my screen name and you will see the threads, they could save you a lot of effort and time. I never got dyamic hair into C5 through "Naitive", always thru "Transport." I played with shadow map lights, raytrace lights, and eventually skylight. It works. I don't know why you are crashing out. I am on PC, maybe its a Mac issue. :::::: Opera :::::
