It is not that there is a line Frank, it just looks too sharp on the edges. For pig iron, if you used the blur tool lightly around the edge of the whole disk, the result would be what I thought would appear as a natural edge to it. Thats all!
Yea
Now that I look at it yes...you could give it the edge treatmet
and make the globe a whole lot more...well..globular!
Thanks Seanie...
I'll give it a go and see how it turns out.
