This is my first ever map made with WorldPainter. I was just goofing around, and made this: a giant island complete with wildlife and a snow-capped mountain surrounded by a vast lava ocean. The mountain is a snow biome, so the snow won't melt, and the rest of the island is forest. I think the lava ocean's a hell biome, so if you make a big enough dark room on it you'll be able to spawn Nether mobs. I accidentaly had Zombified Minecrafter's Better Dimensions mod on when I made the world, so you will find the occasional netherrack, glowstone, or even endstone. I highly recommend the mod. You can play this map as a survival map, or just check it out. Either way, make sure to have fun!
