While texturing Pearl I had a problem with texturing the hair (btw I don’t know why hands decided to become pink. In render view they are a perfectly skinny colour). I wanted to achieve the ‘natural’ light reflection on them so I couldn’t use the any of the normal materials. I have tried using all of the Hair materials provided by Maya/Arnold but I would end up with this not smooth surface after rendering it out.
After consulting with Andy he suggested using aiStandard with noise bumpmap and this is the result. I think it looks even better.
