I do have a problem with hiding strokes, though. In the below example I drew the original shape with a light grey outline, then changed the shade of grey and hid some strokes between points where the shirt overlapped.
When I'm drawing in AS, it looks great. The line isn't visible at all!

When I render, however, a stroke is visible in the original shade of grey used when I drew the shape.

I need to delete the shape, change my colours, select all the points, then create a new shape in order for it to render out correctly. Not too tricky a workaround, but when you're as indecisive with colours as I am this gets to be a real pain when you start introducing new characters to your show...
