When you are in Blender, start by applying "smooth" to the object,
then use the "edge split" modifier > you can specify an angle for auto-smooth or mark hard edges by hand :

I've tried to import a few models and they've imported fine, but they seemed to be smoothed when I imported them. Is there any way to get round this? and is there a way to have some faces smoothed and others not?

thanks,
