Hello friends! It's time to show you my shader for hoar hairs. How it works?
SHADER. I used two different states (colors) for my hair and pluged their into switch. The switch is controlled by ID hair attribute parametr from Yeti. IDUserData reading Yeti attribute and it is controlled in aiRange using custom map painted in MARI. Interesting point is melanine. I added a little melanine in shader to have more natural effect and it's masked by second switch because I don't need blonde hairs on my white hairs.
What now? I rendered it on my workstation until 13 min. per frame and I'm going to make turntable to check if it looks correctly in every side. On next steps I need to render whole parts: skin, eyes, hairs in different lighting conditions and back to texturing clothes of my character.
Test render on mid settings of Arnold in 13 min.
This is raw color for my hairs.
This one is with melanine mask and using aiStandardHair
