Okay, so I have Restock and wanted to add some cool exhaust effects. I heard about the Waterfall mod and tried downloading it, along with the WaterfallRestock mod. I opened up the downloaded folders, and each had a Gamedata folder within them. So I put the files called Gamedata into the KSP Gamedata folder. I open up the game and and I'm not presented with any errors or incompatability issues. I build a rocket with a Vector engine and fly it, only to discover that there aren't any effects added. As a matter of fact, there wasn't an exhaust plume to start with.
I have the latest version of the base game (bought directly from the KSP website), Restock, and ModuleManager. I also have the latest version of Scatterer (although I don't think that really matters)
Is there something im missing, like an extra mod I need? Any and all help would be appreciated!
