So here's a failed attempt for my next render. I stopped it after 50 iterations at still 0%.
And that's good enough to make my question. Here, I used the Rogue Fibermesh Tummy hair for the vellus hair implementation. Even at maximum sparsity and shortest length, with the opacity mask at 10% she still looks like a well groomed ape rather than a girl with fine tummy vellus hair. Victoria 8.1 HD hair are even worse. These don't even follow the body as I pose it around.
So to my question. Anyone has a good vellus hair product in mind? Or settings to use? If a product, I'd appreciate it being complete. Rogue for example has abdominal but not sacral hair.
