One of the great things about the UV mapper in C3 is that you can select individual or groups of polys in the 3D window and then move them about or remap them in the 2D window. (Try the 'detach polys' button!) Selecting the whole lot first and then resizing smaller gives you room to move the bits you want to concetrate on. A couple of quirks in the full version: if you've a set of vertices selected that you want to move/scale then you have to position the mouse over a vertex in order to carry out the manoeuvre. And if you want to resize in proportion using the shift key, start the resize and then press shift - pressing shift at the start means a vertex gets left behind.
