The import procedure for PhysX/Apex cloth is slightly different from UDK and so I couldn’t get it to work for many hours. I then stumbled on a post on the AnswerHub and one of the guys at Epic mentioned the missing details I needed 
I don’t have time just at the minute to write a lengthy post on what I did, but I’ll be posting the full PhysX/Apex cloth process from start to finish in 24/48 hours on YouTube.
I’m working on the steps to have cloth hair on a character riding a horse with the horse having a a cloth mane and tail, The character on the back of the horse will have longish hair too
I’ll update this post accordingly once everything is polished and working, along with a new post to direct everyone to the tutorial. I’ll add the tutorial to the wiki too.
