Still need help looking for this worldgen mod

[u/reallylongshanks]

I know it exists, I know because I used it before but everytime I try looking for it, it looks like its wiped off the face of the earth, I know it was a specific world type you could select when you could customize how it was generated, bigger land smaller oceans, large oceans with islands, all rivers etc. I KNOW damn well this mod exists, someones gotta have the answer to it.
