waterfall doesn't seem to work for me. I've tried everything, but when I test the engine plume effect, the editor says "couldn't find any effect modules on this craft, add modules via config before using this editor.." I don't know what this means at all. sometimes the mod completely craps out and there's no plume, sound, and the editor says absolutely nothing. I can tell I'm doing something wrong but I have no clue what it is.. can anyone help?
