Why does my hair render as a cone? I'm having issues with my hair emitter to show / render as cones. I'm using cycles and during "solid" mode in the viewport the hair looks like normal hair. but as soon as I switch to rendered view or even render the still, the hair turns into cones. Ive reset all options to default, reloaded the same .blend file and ive created new ones. Still does the same thing.
Have you checked the cycles hair settings? The 'shape' option of the hair settings could play a role. Try typing in -0.75 in that area to change it. Are the roots too big?
