Hi
If you mean the lasting smoke time from ships flaks( white smoke)go to MODS\vas_stuka_40_FX\Effects\Explodes\Air\Zenitka\USSR_25mm and open SmokeBoiling.eff with notepad and change LiveTime value(in second) from 15.0 to your desired value, save and exit. The default game value is 5.0.

I gave this a try, but it didn't work out on my end. Me thinks its most likely due to the some of the other mods I have installed. At the moment there's quite a mix.

Eventually what shortened the display was copying the contents from USSR_25mm folder from the Uranium pack and pasting those over what was in yours.
is this the correct thing to do?...I don't know.

With the short time I've had experimenting, by adding files to my mods folder, I've seen some strange things happen. Most of which are probably from conflicts.

Keeping the files structure process in mind is the key....it isn't the easiest for me, but I'm starting to get the hang of it.

Thanks stuka_40
