I'd like to help. I'm also have a Breath of the Wild project. It's a Resource Pack.

im sorry to say that this map wont come out. but i will be making a server where I build a BOTW map so everyone that want to help msg me on discord at: Elias#3840
thank you all for the support<3

I'm currently making the entire map. Trust me when I say it is a lot easier to just find the height map on google and import it into worldpainter. I researched the size of the map and while many people overestimate it's size to be hundreds of square kilometers, the most accurate answer I found was 61 square kilometers. That translates to a map that's about 7810x7810 if you want to make it 1:1 scale. (although the dimensions may differ slightly from that because the map isn't perfectly square)

Heh. This could take a bit... ((Or a FLIPPIN FEW YEARS))

This is already amazing!

that's giant!
