Tiles/Endless Terrain

I'm kind of interested in the Endless Terrain art library add-on, but I'm a little foggy on their use. Do you plop down fifty of these to make a map? Do you use one of them and just make it really big? Are there some sample maps made with these tiles somewhere? How come the Snow tile from Endless Terrain shows up as just a square with "Roll 20" on it? What's the snow tile actually look like?

You can set down a number of tiles to make a full map, yes. The sizing (expanding individual tiles) would be your preference. All the content on the Marketplace is watermarked-- when you purchase a set, you get access to the files without the logo on them.
