Hi and welcome to today's question.
I'm putting some fur on an object using nurbs curves. When I set the
diameter of the curves to less than about 0.3 mm the rendered curves go
fuzzy (they look a bit like pipe cleaners). They have no material, no
displacement, quality setting and retting setting doesn't matter. Is
this expected?
I can scale up the whole scene and it seems to work. But the internet
tells me that "...In my research, I have found the diameter of human
hair to range from 17 to 181 µm (millionths of a meter)." So to render
hair at real life dimensions needs the curves to go to 0.02mm, and even
a scruffy old drunk like me doesn't have hair .3 mm thick, as I trust
the Internet not to lie to me.
