Working on a very gothic inspired build with some really nice looking real life reference images. I'm of course taking liberties here an there, but I think it's definitely gonna be a show of what I can actually do as far as making architecture, and it's helping me get a little more comfortable with just adding more complex decorative geometry. I'm really just trying to see how much I can push the engine with the scope of the build and the complexity of the architecture. Stay tuned, I'm currently about 1/4th the way done and I started about 6-7 hours ago, so it's gonna take significantly longer than most my maps.
**UPDATE 1**
This is by far going to be my biggest map. I don't even have the two side towers on the cathedral finished and haven't even started on the main cathedral part yet and it's 2800 brushes and the BSP is 2.63mb. This is likely not gonna be a map that's going to be played on and just strictly a show of what I can do, so I'm gonna just really focus in on detail rather than function in gameplay or any other real purpose...basically I won't be adding stuff I'd normally do to make the deathmatch experience more fluid and fun. I really love how the map is looking so far, and I might even experiment with more texturing stuff, though honestly the cathedrals I'm looking at don't have much variation in that department so maybe I'll just stick to what I know and not deviate too much cause it already looks fine.
Anyway, that is very nice, keep going! My largest map was probably 12 MB with lord knows how many brushes. Just make sure it's optimised enough and fits within BSP limits.
