50cal - look back a few pages to find detailed explanation of how to take the house fires and use them elsewhere. Although there's no reason for this compilation not to work if you're not using any other mods if and there's nothing wrong with your main game install. Maybe try re-downloading or something.
Manysh - I'm so busy trying to sort out everyone's nav lights it's a wonder I have time to go to work! It's a weird one, but the fuelS folder doesn't solve the problem for the fuel tanks Slipper was talking about. That tank seems to use fire effects from more than one place. Dunno how! ???
Hanzie - I'd do what Manysh says but put the up class files (not folders) in my v4.1 instead, then it should be switchable in JSGME. And delete all the class files from my mod first, just in case. You will be missing one class file but don't worry about that now - let me know if you get it working and I'll sort out the missing class file for you.
Night all
