The white painted brick used for the walls of the house..I can't seem to find how to make it, so what is it? Is it still in the game? Thanks!
That would appear to be the soft brick tile. (I use that in my race mod's towns.) You obtain it's crafting recipe once you pick up your first piece. However, where you find it in vanilla is beyond me. Also, I agree, that it is a sexy piece of brickwork.
What Wolf said, it is indeed http://starbounder.org/Soft_Brick and can be found in Avian villages, or also in Steamspring Sub-biomes.
You can also find soft brick on surface floran shrines. They'll usually look like a small "castle" with lots of plant matter blocks twining around the brick, there will be black scorpions and hostile floran, with a few crates and lamps. They almost always have two floors with a stairway up to the second floor.
Aaaand I'll add that Glitch Towns also spawn it. Really abudant, really cheap, also looks gorgeous when painted.
