Going through the tutorial as we speak. Thanks, BB - the renders are incredible. It really brings out details P7 choked on. Of course, I had to push it to the limit and did this obscene render setting in P8 with transmapped hair (visible in RayTracing on) and min shading rate at .5 and 8 pixel samples, 2 raytrace bounces, all on my poor little P4 single core 2.8gHz with 1 gig of RAM. Wasn't happy with me this morning: it had only rendered half the image (the hair half) after 7 hours of chugging.
Finally finished now: wonder which setting I'll be turning down first so speed things up a wee bit. 10 hours is a bit long, maybe, for a tutorial render. Perhaps I should read a bit more of the thread and then ask this question again... :rolleyes:
