I am experiencing creases on my subdivided model when I apply my displacement map. This is also happening in c4d when I apply the map. The creases are happening on the original poly flow. I can’t figure out what is causing this… 
Hey mgibson,
I think I’ve just had the same problem as you’re getting here. The only thing is I was not getting this problem in zbrush, or at least I didnt notice it. I had smooth UV turned on and that seems to cause these creases. I also had adaptive on too and that messed up my geometry a little too. I’m exporting everything to Max and I dont know if its different in c4d.
I hope this helps.
