OT. Retrieved objects from Fallout 3 and rendered it.
I finally thought seriously about getting stuff from a computer-game, import it into DAZ Studio and render it. I watched this tutorial at Youtube to see how they do it:
("How to extract and get 3D models fro Skyrim to 3DS max modify them")
It pretty much works the same way with Fallout 3, so that's how I got the power-armor and the helmet.
