I've been having this problem for quite a while now, but I've never bothered to post about it till now because I've just been using SMD instead in its place. For the record, I never used to have this problem with DMX, but somewhere along the line it changed.
I'm running the latest version of WW Pro on Max 2014. 2016 produces the same result, so it's not the older version that is the problem.
This is how the model should look (body exported with SMD):
And this is how the body looks when exported with DMX:
As you can see, the rim lighting completely bugs out on DMX, and the phong screws up too.
It gets even worse in SFM when you combine ambient occlusion in the mix:
