Wheels. Jagged edge

[Mr Mufakka]

I was messing around last night and modeled the wheel below. I'm still a n00b so I'm just doing random items. It was rendered with the trial version of Podium.

Anyways, two questions. The perimeter of the outside of the wheel and even the center hub... the outside isn't quite smooth. Any ideas why?

Also, in the second shot, there is a white line going around the wheel right inside the outside lip. Any clue what could cause that?

Again, I'm real new to SU so it might be the way I'm modeling/grouping components that is causing these items.

Mufakka,
You can increase your circle segments in SU and thus making it smoother for rendering.
When you draw your circle click on its circumference go to entity info >segments and
Insert the new value inside the box, maximum is 100.
I don’t know about other podium rendering issues that cause such behavior because
I don’t use it but there is probably someone here on the forum that can give you
advice on that.
