Make fur mesh

Say I have a flat modeled mesh.

I want to make it fluffy, but I also want to make it so it preserves the fluff outside of blender, if I export it to a .obj for example.

  1. How do I make the particle system

  2. How do I convert it to a mesh?

Hi, create your particle hair then click convert in object mode go to object>convert to>curve from mesh.
in the curve setting set the extrude and depth and resolution to very low setting then go to>object>convert curve to mesh.
