Well, I sorta had that doubt too. And I confirmed it in a few maps. Thanks.
But after trying to build more stuff I realized my problem is really more with the ceilings (and 2nd floor floors - which you already covered a bit now). Wall height is just another thing that comes with it.
I often ask myself what ceiling height to make in certain situations. When I refered to the two story interiors, my real problem was what height to give the 1st floor and what height to give the 2nd. Probably the same height, but what height?
As I understand, heights are the same inside and outside, 128, 192, 256, etc, but what's the appropriate height for a certain hallway or room is what gets me scratching my head. I've been observing some maps and I've come up with a mix of more confusion and a bit of elucidation.
(I think my problem is also related to me being used to hl2 dimentions, which relied much on 128 tall ceilings. Here, everything is slightly bigger.)
Just a few examples:
- 2Fort's intel rooms have diferent ceiling heights in both exits. One of the exits (the lower ceiling one) gets higher after turning the corner. The intel room itself is even higher. I can't get the meaning of it. Only thought that maybe it's best to make 256 in places where we might add much detail, like in the intel room. But then... looking better, the ceiling there is 304 tall, not 256 as I had expected.
Entrance halways are 176 tall, which makes the upper floor be 192 high. I think I see the connection there, and this fits what you just told me about 2nd floor height. But what made them choose 192, is still a mistery to me.
The storage shelf to the left of the main spawn is only 160 high, maybe this is arbitrary?
The basement resuply entrace is only 128 high. The inside is 224. The entrance height may be to conform with the door model or the cave displacements.
- Gorge made me think that maybe a good height for an industrial building is 256 for both floors, but the second floor ceiling often gets much lower with all the details and props than the first floor.
Then I found a room unnaccessible to the player that has 160 ceiling height. This means this one is on a 32 grid.
I forgot some others I have seen...
Maybe this is all a bit arbitrary, depending on concept design, or maybe I lack a few basic concepts of architecture, and decoration too, perhaps. I don't know. I'll keep looking at maps and maybe I can find a pattern or something else that may help.
