Geometry in unity

Can i improte Smooth Objects From 3d Max Or maya to unity or should i increase The Polys To make it More Smoother?

I believe Unity imports the smoothing groups from 3ds Max. I don’t know about Maya, as I’ve never used it. However if by “smooth objects” you mean smoothing groups then yes, Unity imports it. You may need to increase polys anyways depending on how smooth you want the object to be.
