Neat!
It's fascinating stuff, too! How much work was involved in the Town Hall building, as an example?
Town hall... If I never have to work on that building again, It'll be too soon.
Heh, Sorry. The town hall was the very first building I started working on. I was pretty much learning everything as I went, as well.
Basically, for any standard object. I use a method that I picked up waaay back when from Arcanaville, to pull a capture of CoH as it's running. (Thank you, Demos.)
This capture is a huge mess of everything that's being rendered at that time. So if I want, say, the Blimp. I have to pick out the blimp, and delete everything else. (Which can sometimes be quite a pain). Next up is making sure the model doesn't need any editing, some of the old models are...old. But we'll skip that for now.
The next part is by far my least favorite: re-skinning the UVW Mapping. Basically, in non-game-dev speak, this means attaching the texture so it shows correctly. So that the numbers on the side of our blimp are, well, actually in the correct spot. This is not an easy process, nor a fun one.
If everything looks good, I export the model and then import it to Unreal 4.
...Then I realize I did something wrong, and have to go back and fix it. Repeat that a few times.
A simple object like a trash can might take an hour, one of the pretty skyscrapers in Atlas Park tends to take a few days.
TL;DR: City Hall is my most hated object in Atlas Park now.
