Here is an image of the imported model in Zbrush and how it looks in Maya when I imported it over. The edges are all hard and the rest is smooth. I still don't know why it's coming into Zbrush this way.
That's how ZBrush works, all meshes are faceted. The only way you can make it appear smooth is by adding actual topology. Here's a more detailed explanation... AskZBrush: “Why do meshes from 3ds Max appear faceted inside of ZBrush?
Thank you for the tips guys. I found a solution I'm just going to increase the subdivisions in maya before i bring them over to Zbrush. It already looks better.
