"The doorway on the left seems wider"
I noticed that but I haven't re-measured it yet. It could be the renderer, since GES and Source are very different in how they handle FOV, but the image matches up so well I'm not relying on that.
Edit: Fixed. It was the correct width, but it was one tile to the right, which made it look wider because it's more distorted at the edges of the view.
I may or may not bother with the ammo boxes. The most common 007 orientation is 90-degrees from Source and I'm not going to dick with rotating them all by hand.
0.225% is pretty good. Complex is going to be something like 104%; its base width is both very tight and it comes out as about 15-1/3 in hammer units so rounding down to 15 would make it even more claustrophobic, and rounding up means I'm actually on a natural (binary) unit for a change, which is very very nice when working the textures.
