All default vanilla fluid generators are kept. Don't be spooked by the icon, it was the best I could do on my limited time and art budget
Immersive Weathering adds many new fluid generators that allow you to automate nearly every stone in Minecraft. Unfortunately, this adds inherent balancing issues in the presence of mods like Create. To resolve this, I've opted to disable all of these additional recipes. Vanilla fluid generators, and all other modded generators, will still work as intended.
The only disabled generators are the ones that allow you to make stones. Moss will still be burned, and clay and sand will still be affected by lava.
If you'd only like some IW generators to be disabled, just make a datapack and replace the fluid generator you dislike. You can do that by making a new json with the same file name and namespace, and then only putting {} (a blank json) as the file's content.
If you'd like to add brand new fluid generators, you're on the wrong mod page haha. Check the Immersive Weathering wiki though, which explains how to do it (and provides an example): IW wiki
