i don't understand your point excaliber. what's the different between using 1 texture file with size 3072x3072 or two files with size 2172x2172 ? both options will use same memory, the only difference i can see it's that most cards won't be able to use 3072x3072 textures, so it will either probably get cropped or resized. and anyway i think one house doesn't need that much even if it's highly detailed. i'm referring about a house with exteriors of course.
Well, thats my point. Most wouldn't be able to hold a texture that large. Also, I believe (could be talking out of my rear though) that it is faster to reference multiple textures that are smaller than one large.
Also, I thought you were refering to a house on the inside as well (ie. all the outside textures as well as interior textures).
