Does brush-scaling (GTKRadiant 1.5.0) come with any problems

[monaster]

For my map babylon I (temporarily?) scaled up an entire building consisting of already clipped brushes (2-way-clipping) to get that ueber-temple you can see in the picture below:

I couldn't find any problems such as brushes out of grid, the sudden emergence of small spaces between formerly adjacent brushes and so forth. Or is there anything that could go horribly wrong if you use the scale function (with brushes, not patches or models)?

Well, when you do that what you usually get are brushes that come out of grid, cracks between coplanar surfaces, etc. If you're sure there are no artifacts in both the editor and in-game, I guess you got off lucky.

You may also want to give the -scale function a go, though it will scale your entire map at compile time.

Thanks for the info. I guess I'd rather not rely on that tool in the future then. Experimenting with the -scale compile function might work though if I got you right (I just have to make the ueber-temple its own map and copy paste it afterwards, that should work).

You can't copy/paste. It compiles the BSP with things scaled up, but your original MAP file remains the same. I suppose you might be able to decompile, but that's probably more work and may be prone to other unforeseen problems.

Good to know.
Then it's probably the best method to manually rebuild each single brush inside the editor OR - if it isn't a building too complicated built - change the coordinates inside the map file opened with a text editor (would require a calculator and some abstract 3-dimensional imaginery skills though).
The reason why scaling up several brushes at once inside GTKRadiant 1.5.0 actually worked for me, is probably because I scaled the temple's lenght and width at exactly the same ratio and because these two dimensions have already had a square outline (although not cubic if you added the height), so it wasn't that complicated for the editor, but in other cases I can very well imagine now that problems as described by you might arise. Thanks again!
