ReStock Changes the stock models and replaces them with it's new models[in this case the engines], which means that Stock Waterfall Effects will likely have some problems since it's designed to add it's effects based on the stock models, not on the ReStock new models.
I suggest you to download this mod. It adds waterfall effects for the new models of ReStock.
@Kerbal Productions i sent you a PM of the Science Def Code, btw, you may notice some spaces like this:
Neus NadavoLowWathev = oof
I made that since the planet you were trying to add science defs had a different name(Neus Nadavo), you typed NeusNadavo on it, this means that the patch will refer to a null body, and not the target, however, if the target name was Neus Nadavo, the patch would work fine.
By just fixing the typo, It will work very well(though i had a MM error, but wathev, it wasn't that harmful[also, i think i fixed it after testing it, but i'm not sure if it works])
Btw i just realized that you added Science Defs for the Thermometer and other stuff, but not for the other science instruments(Thermometer, Barometer, Grav thing).
I also added a small thing on every line on the code, you may not notice it, but it's a replacement for the space.
And make sure the file with the code has the .cfg Extension, it will not work if you type the extension as .txt!
