Ungrouping

As part of learning to map in tf2 I'm going through some decompiled Valve maps and pulling them apart to see how they were made. There's a building on Gravelpit that is grouped together. I've moved it to a new file to get a better look at it, but it's grouped together. I keep selecting ungroup but the pieces stay together. What gives?

That didn't really answer his question. Looks like he's trying to "ungroup" a bunch of brushes that are not in fact grouped, but actually a func_detail. You need to select "Move to World" from the same menu.

That's right, the buildings in Gpit are Func_details.

Keep in mind that's not exactly the 'best way' to build. It works in Gpit because each area (Blue, A,B,C) are all one large area, but sealed off from each other good.

Making those buildings world spawn would cut up the vis into a ton of visleafs , and since they are full of windows you'd never be able to seal them anyway. So func_detailing probably reduces the visleafs in the area by 1/4 which is a pretty big optimization.

In that case it's better to have everything render at once then having a million leafs and probably still rendering 75% of everything anyway.

Most maps though are sealed more, have more solid walls, fewer windows, larger buildings. So func_detailing the buildings in Well for example (center point of CP_Well) would be worse for performance.

Ctrl + Shift + W Returns func_detail'd brushes to the world
I believe thats the shortcut for it anyway, I use it all the time when I'm mapping out alpha's. (I tend to func_detail a lot when working with rounded brushes)
