worldgen Changing worldconfig settings does nothing for server

[Ryan Patrick]

I have a bisect hosting server, I have been trying to get some significant amount of water to generate in the world, but no matter what settings I have set for landcover or oceanscale, I have seen no changes in the world generation.
I have tried the rivers mod and the rivergen mod, and both seem to do nothing for me, so I can only conclude the issue is elsewhere, the only other mod that I have that affects world generation is better ruins.

So i have been struggling HARD with the same thing, i finally got things pretty dialed with these settings and the rivergen mod, I'll include the rivergen JSON as well cause that took alot of tweaking. Top code is the worldconfig settings for server, second is the json file (just delete the data rivergen makes and replace with that). Hope this helps!

The huge part with the rivergen mod i figured out in the bisect console. The spawn chances in the default file are decimal but as you can see in mine for some reason bisect needs them to be just the value so instead of say .6 for riverspawnchance it needs to be 60, from there just tweaking the base depth does alot. Discovered this by watching the console during worldgen, you can see the errors throw for rivergen

once you have the settings in just delete the world save and restart server then login and it should gen a world with proper rivers and lakes and what not
