In case you didn't see the thread I posted on this in the main SH3 forum, by "god's lightswitch" I mean the way the sky flicks bright/dark/bright/dark in the periscope view when water washes over the scope?
Well I fixed it! lil ol me fixed it! W00t!!
So, in case anyone else would also like this fixed...
The "lightswitch" problem is caused by the sky images in the SkyColours_XXX.dat files (Sky_atl1.tga, etc). I opened them in a freebie image editor and noticed that the day-night-cycle image seems to have two... er, channels? Layers? I don't really know image lingo but one "channel" has the actual colours (the night-time colour is blue-black in my version, which is the GWX version) and the other channel (a transparency channel? an "alpha" channel - whatever that is? I dunno) is grey for the night-time.
So, I fixed the problem by re-saving the images as single-channel images (just the colours) and voila - no more lightswitch! WOOHOO!
I can't be the ONLY person who found this anoying as hell
When you apply this "fix" the effect is to have the lights "on" all the time. This doesn't brighten anything except the sky, and even that is only bright because the night-time colours in the aforementioned images are quite bright (at least in the one's I have they are - mine are GWX, haven't looked at stock yet). You can fix this by just darkening the night-time colours (all the way to pitch-black if you want) and you're done.
I know how fussy everyone is about their colours so I thought I'd post the info rather than a mod (especially what with all the potential mod interdependency issues).
Any questions, put 'em here and I'll try.
