I am going to host my semi-survival server on the 1st of June and I am looking for a good seed / map.
Now what I want is like a big island (around 5000x5000) that contains all the biomes and is surrounded by an ocean.
If you know how to make this or have a seed like this please let me know.
Try to use WorldPainter, to get there click here
World painter isn't going to help me unfortunately. Maybe if someone is very experienced with it they could make what I am looking for but I doubt it.
You could also use mcedit to set biomes around the island
True that would be really easy to change the biomes but then I still have the blocks that are from the previous biome.
So for example I could make the island with the desired biomes but if I would change a desert to Mega Taiga then it would still have the sand blocks and not the actual Mega Taiga blocks.
