Quote - if you have something that is still fuzzy... this sometimes happens with hair.... you will need to select the object and go into properties and lower the shade rate there (0.05 to 0.02 are pretty good) and also lower the "min shade rate" in the render settings.

it will take longer to render, but will be clearer.

 

I've looked pretty hard for 'shade rate" inside my hairs properties and (since I'm so much more used to P5) I do most of my work in the advanced style materials room. I've seen and made use of the setting in the render settings window.(shade rate that is). But where are you talking about it in the object properties at?
