Haha, I was watching the little heads moving about, and thinking "huh? why did Matt suddenly jump over there", and then thinking "eh, why is someone putting a bunch of bricks in the swimming pool?" and then I went "meh" and looked back at plates, and after a bit in the corner of my eye I saw a weird thing, and I looked and all the "bricks" had gone, along with a bunch of surrounding blocks. :D
Now everyone has gone offline or afk though, so I've got nothing to watch. :(
:-D
The glowstone lava doesn't look as good as I'd hoped, but I'm not going back and changing it now, I already drowned enough times filling it with water.
That was probably me and my 128 blocks of TNT, trying to "dig" the other end of the pool out.
It's going to take a while. I think getting a block editing plugin might be easier as there is a lot of obsidian at the bottom and some stray bedrock blocks floating in mid-air :(
That's easy enough. You put a layer of dirt into the pool, one block below the level you want the water at. Fill that area above the dirt layer with water so that it's smooth, then dig the earth out from under it.
