I'm finding the FBX export to 3ds Max to be inconsistent, I have installed the latest FBX plugin. It's kind of odd, I exported an FBX earlier today and it looked fine, I then had to change my units in 3ds Max as I want to output eventually to Unreal Engine 4. After changing the units I'm getting shading issues in 3ds Max, as shown on the attached image. I then reset the units and tried another import but I'm still getting shading problems, I've tried exporting all sorts, ngons, quads and triangles, triangles, all have the same shading issue.

Is there a definitive workflow?, I am importing a Rhino file to MoI, then exporting and FBX from MoI to bring into 3ds Max.
