Shell Fur Techniques?

Dear Unreal Forums,

I am sort of new. I have been watching the forums for years and have even used some advice to get started (all the way back in the UDK days). I am no expert, but I do want to create well crafted games. So, I was wondering if anyone had any resources on the Shell Fur technique to applying fir. Sadly I doubt nVidia’s Gameworks will be of assistance since I hope to optimize for iOS and Android. Anything on the subject (including books, forums and tutorials) is much appreciated!
