As usual i opened my big mouth too soon and things havent gone to plan.
Comping extra element into the trailer was always going to be a bodge, but i`m realy not happy with how the hair works at the moment so i`m going to re render the whole thing. It`ll take a few days but the end result will be far better as all the shadowing and lighting will be 100% correct
Heres a frame of the re-rendered trailer.
and a crappy preview of hair in motion..... or lack their of actually
