Affecting visual ranges

[lancerr]

I know there's have been dispersed sets of discussions on affecting visual ranges in SH4 (but as part of other thread) but I wanted to see if we could create this thread to focus on that issue alone.

I am attempting to mod the excellent work done by Xantrokles on the Pocket BB to allow long range ship to ship combat.

Currently, I've been able to change the optical zoom distance for the deck gun to correspond closer to getvisual ranges of detection. However, a critical part of surface gunnery was to be able to spot the fall of shot through shell splashes and adjust for the next pattern.

That's where I'm running into problems. Adjusting zoom, shell splash height do not seem to affect the visibility of shell splashes and currently, I can only see them out to 4500 yards.

Does anyone have any ideas on where to look to modify this so that shell splashes can be seen out to 13000 yards (which is still less than the ideal range but we can work on getting small improvements first).
