Performance cheap fur shader?

Hello, I am looking for a cheap fur shader.
I need it for a character that is quite far away from the camera.
What I need is not seeing the individual fur hair, nor the smooth effect on the silhouette.
I need only a smooth surface that globally gives back the feeling of fur and not of plastic or something similar.

Some time ago I recall I had read a document about digitizing the behavior of different materials.
An example was a wool pullover.
The technique was simple: the material was photographed with different angles of inclination of light, so to reflect perfectly the light behavior on the material.
And it was quick of course: just a lookup table where to take the values.

Now, I don't know if there's anything similar for real time, and I don't know if I need it, but I suspect I don't.
Anyway, do anybody know about a performance-cheap fur shader?
For PC, not for mobile.

 

Most fur shaders i know use a simmilar technique as parallax occlusion, where you layer the textures on top of each other with an offset and a step amount.
There are some good examples out there and you can adjust the sahder with the step amount to where you seem fit, so wager the performance with the quality of the fur.
