I'm sorry, my fault. All this "Is" layered in PhotoShop. I didn't explain well enough. Each clip of the different colored/material ships "Is" a Bryce Render, Then I use the "Mask object" render in order to cut the ship out of it's original BMP format image with PhotoShop. When I said there is No Postwork I was referring to brushed out or Special filters used to alter the original render. I'll post the WIP so far and you can see the difference.
