This is my entry to Compo 23 - with a very original title! Although mostly complete (I could have done more outside) it does show some max entity errors in dev mode which resulted in some features not appearing correctly - ie, the outside water feature and the glass walls.
Purely cosmetic, although on entering the indoor area there is a button on the left by the wall light - press and turn around to face the pool - I won't spoil the rest!
MOD FORMAT - with custom menu .avi title (approx. 5.5mb external host)
The HL2 textures look good, but the default water texture you chose is actually horrible...
*When making a waterfall, make the scale of the texture in the Y axis a bit higher, to give it a good distortion and sense of speed.
*When making a multiple-brushed waterfall, use alt+right-click to give each brush the same alignment values. In some parts of the mini-waterfalls, some segments had the water moving in a different direction!
+ Anyways, besides all that the map was pretty neat. The splashes coming from the waterfalls was a realy great touch. I realy liked the small waterfall coming from the spa. For a big pool area, i could say you pulled it off.
The waterfalls at the beginning did have sound, strange that they didn't work for you though. The glass was also one of the issues I had with the max entity limit, and grouping them didn't seem to help. I agree about the swimming pool depth - i thought about that at one point but completely forgot to take it further.
If I have some spare time, I might work on this some more, and maybe try and show off some more of the HL2 textures.
