I am at the library so I cant get a screen to you today, but let me try to explain a little better.
I have mad the car, and then I split it into more manageable chunks in separate layers.
So for example I take the bonnet. I hoghlight the object, and then I go to convert polygons to sub-d's. There are two number options in this box and I dont know what they mean.
Any how as a result of clickijng this every one of my individual polygones which form the bonnet, turn into circular shapes- yhey become detached and form these shapes, it looks wierd.
