I'm currently using the most recent version of the mod with shaders, but they won't apply water shaders to the stream blocks, I've also tried copying the file from the .jar archive to the shader pack yet it still doesn't seem to work, could I possible get help with this issue?
The Meaning of Life, the Universe, and Everything.
Not trying to be rude but has their been any signs of the mod author sill working on this mod? According to the github the last time he worked on the code was on August 2018 and since then there haven't been any updates to it. He does respond to some open/closed issues in the github but that's it so far I can see. I'm just wondering what's the state of the mod since there is/was supposed to be a rewrite of the mod happening but has ever since died down.
I'm still around, just not very active in modding right now as real life got in the way. I don't expect to do much feature development on my mods until Forge 1.13+ is released, but in the meantime I'll still release bug fixes as needed. I've seen quite an influx of new issues recently, and hopefully I'll get the chance to address more of those this month.
Is it possible to set the chunks to repopulate and the rivers spawn in existing chunks?
Not currently. That would be a difficult feature to implement, as the rivers generate in raw chunk primers composed of only stone, water and air. It would be difficult to tell an "original" terrain shape from a generated feature or player-built structure, and you'd end up with lots of trees and other decorations suspended in mid-air above valleys.
Could you make the rivers stronger where some are very fast flowing while some are weak and slow flowing or add a setting to change it globally?
It wasn't possible back in 1.7 when I first created the mod, but I noticed recently that animation speed has become a configured attribute in the water texture metadata file. So that might be possible in the future, provided I can find a way to change it at runtime and to make different speeds interact together in a not-too-ugly way. I'll look into it, but no promises. :-)
There is a few problems as of the 1.12.2 update, first of the water current flow lines are gone, and boats sink all the way to the bottom after going down a waterfall. Yes I did try it with mods, then without any other mod. I want to be able to use this mod properly as soon as possible in a series. Hopefully it will get fix soon, or is it only happening to me.
