Note: both flaksplash and flakdust are also tweaked to provide the same effect of the rollfix mod (see the rollfix mod page for explanations).

Many thanks to Ken Wright who suggested the idea in this thread on Combatsim!
The effect looks very nice when you are attacking naval targets, as you can see below:

Unfortunately, since there is only one set of flak effects files, when you deal with land targets you are strongly advised to use the following version instead, which provides a dust cloud on the ground, rather than a splash, as you can see in the following screenshots.
