Hey gyarados, thanks for the kind words. I got to agree, now i am starting to think it was too much noise
Any ways I ensured your questions, hope it helps
Any other question please ask, I know there is not a lot of material out there, I was looking for it too.
1-I did the head body and tail as individual parts, so it was 17000 for the head 25000 for the boddy and 6000 for the tail.
2-I didnt like the results with the vrayhairmtl, But I did not try too hard, lol, after some tests I saw the results were coming better with the standard hair material so I decided to go with that.
3-My test renders were taking about 1 hour or 2, depending on the hair count, my final render with high res and all the passes was about 7 hours. but my computer is not too powerful, its a 3 years old i7 with 12gb of ram.
4-Yes I tried less curves, more curves gives you more precision on how much the shape will look like the fibermesh shape. but the number of hair and options like thickness and frizz will be defined by your settings on the hairandfur setup. but more curves will take longer to import.
5-No I didn’t, I should try it some time. I used irradiance map + light cache
