>>2173490this is probably my best render to date. 2.5~ hours. i tried something new with strands of hair, and I think it worked quite well.
>skip strands when masking at first>come back later>set original layer (duplicated at start) to top layer, fade it a little>trade strands at 50% opacity in layer mask>paint over strands with hair colorThe rest of it was just... going over each side, erasing and revealing in the mask, until nothing was faded, all the borders were kept nicely, and no halo-ing.
