Some more news from pc modders
"Greg and I are pleased to announce that in the next version of the tool, iffs will be read by the game externally, and importing will no longer be required. Just drop your files into the directory, and you're ready to go.
Stay tuned"
"Also, because of this progress, 3D editing is looking very likely"
They also said we wont need to use any back up files anymore with the updated version... amazing stuff considering the game was released like a month ago.
