Terrain

[Vapey]

is it possible to get a 10k by 10k custom world (trees, structures, etc). I’ve asked in the past and people said its to hard to render a map that big.

I have a world like that lying around if you don't want to wait, actually.

The main problem would be structure, since filling up a map this large with structures would be expensive even from a super-cheap builder. I suggest considering copypasting builds from free buildpacks unless you have a very significant budget.
(I don't know if this is the type of terrain you're looking for, but I thought I'd offer. Feel free to make an offer on what you feel is a reasonable price, I might consider it)
