I made an assumption thinking if I export an obj of the fibers it would turn out the same as zbrush render, but all I get is the jagged triangular shapes. Not sure if this is normal or I’ve done something wrong ?
Using Keyshot btw.
Keyshot doesn’t have any native ability for subdivision. If you want to export low poly geo into it, you’ll have to subdivide the obj first, or if using the Zbrush to Keyshot bridge, just turn on dynamic subdivision for the hair subtool first before sending to keyshot.
Thanks, works good. 
I also assume it would be better to use the “profile” to get more sides and not “bpr sides” as I’m not rendering with Zbrush ?
When sending Fibermesh hair to Keyshot, it’s best to have it UVd first so you can import a texture and transparency map, or just a transparency map so you can apply a colour to the mesh in Keyshot.
