I can't upload zips to pastebin, or at least I don't know how. I did try, sorry. The condensation is always visible even when the sound effects aren't working. Personally I think condensation is to visible, almost luminescent at times, maybe make it more translucent? I'd been having trouble with conflicting module manager files, when fixed by removing unnecessary MM files from game tree the mod behaved slightly better but the issues I highlighted were still largely present. Maybe try producing a module manager file specifically for this ? I don't know allot about these though :/ It could also be conflicting with other mods I have installed: RCS sounds (contains own Module manager.dll) Mechjeb 2.1 ISA MapSat 4r1 S.C.A.N sat F.A.R (contains Module manager.dll + MMSerbianExt.dll) New rocket sounds (but unlikely as just replaced sound files) Deadly Reentry P.s. A slighly visible 3d shockwave cone when supersonic would/could be awesome! Good luck with the mod! Really wan't this to develop so let me know if there's anything I can do to help iron out these issues
