Hey,
as a part of bathroom scene I created a rug with hairs.
I´m having a weird problem, my hair partially is disappering in the render but only if I before have entered particle edit Mode and combed the hair.
All the hair is rendering fine as long as I have not entered particle edit mode. Once I enter particle edit mode and do just a single stroke with the comb (and exit into object Mode again) the majority of hair just disappears from the render. They still all show up in the viewport before this render but after the render has finished they even disappear from the viewport.
There is no correlation between where I comb the hair and what patches of hair disappear.
