Hey, I am playing with forge 43.1.1 on 1.19.2 with effective_fg-1.3.4 and it seems that the cascade effect doesnt work. I only saw blue particles when looking at waterfalls. I also saw some comments here on curseforge where people got a similar problem.
Love this mod btw ^^

I'm also having this issue with the latest 1.18.2 version of the mod. The mod doesn't seem to register when the water is falling into other water anymore. Also, as a side suggestion, would it be possible to add a min height for the cascade effect in a config? That way the player could control how big the waterfall needs to be to get the effect.

Correction, this seems to an issue relating to this #23 (comment). Not sure if this is an issue on this mods end of on rubidiums side.
