Unlike a ship a sub back then did not have the stability with such a rounded under side of it. That is normal to see that.

Understood LV. It's not the amplitude I was questioning... it's the frequency.

Perhaps a result of the boats in the game having way too much freeboard, which may itself be a result of not enough "mass" (or whatever the appropriate value might be)?

#2 looks good. #1 would force me to keep a bucket by my computer

Yeah - that was bothering me a bit too. I think I may have figured out what controls the rate of roll for the sub

It's looking better (I think) in my last couple of tests. Still gotta run some more "collateral damage" tests though to be sure. One avenue that looked very promising from a pitch perspective on the surface turned out to be a real sub killer - when I did a crash dive timing test, the timing was pretty good but the sub just kept right on going down to 600 feet and beyond with no sign of leveling off

So far this latest combination seems to have retained decent pitch/wave action yet dampened the roll speed with no ill effects on diving, turning, etc., but I'll have to run it through its paces in some different wind/sea states tomorrow to see how it holds up.

Two!

I dont like eather. Did the boats pitch side to side like that? I had it where I liked it then I installed ROW and it messed it up. I would rather have one where the boat just pitched lateraly and not Side to side myself

a 300 foot sub is not going to pitch much, but i think it will pitch more than our stock SH4 installations. I think leo got the rolling close to where it should be with his latest ROW.

Regardless of the higher freeboard of the US subs, they rolled liked crazy, just the nature of a rounded hull boat verse that of a normal deep V hull. You can get a sense of this when reading Silent Running and Iron Coffins, especially looking at the pictures. My life experience is offshore V hulled type boats (50-60 feet)

i really like video number two. I'm not happy unless im on the verge of getting sea sick while manning the bridge in anything other than calm seas.

Ok - thanks for "pitching" in here and helping out.

I don't know how to change or add a different poll to this thread, so I will be launching a new poll/thread momentarily and asking that you compare a new video with my latest set of tweaks - I hope you'll keep your eyes out for it and check out that thread that will be up in a few minutes.

Hawk_345 · 12-09-07, 11:25 AM

Well from what i see here now, take 2 vid is the best looking one, but im thinking in a real life situation it wold not be pitching that mutch, unless in fairly stormy seas.

DrBeast · 12-09-07, 11:25 AM

I hope we'll eventually learn what it is you're tweaking...I'm dying to test this out myself!

Nanotick · 12-09-07, 08:01 PM

I like #2 better. I'd like to see a side veiw movie clip to see how of the boat comes out of the water.

EAGLE_01 · 12-10-07, 07:58 AM

So, How's it coming? I've been looking forward to this mod.....

Momentarily on hold for a few days - since all this was being done on top of ROW and stock behaviors were potentially rather different, and because I have no intention of ever playing this game without ROW in some form or another, I temporarily suspended my testing until Leo had a chance to get ROW fixed up for 1.4, after which I'll jump back on this with a vengeance.

FIREWALL · 01-03-08, 09:02 PM

#2 is my choice but don't stare at the video to long "URP"

I better get back to playing and get my sea legs back.

That clip made me a little woozy.

Thendash · 01-04-08, 05:03 AM

I thought take 1 looked better. Take 2 looked like it was going against the waves, like the waves were coming from right to left but it looked like it was rolling left to right(If that makes sense). Same with the up and down bit, yeah the waves "crashed" over the bow but it looked like it should have been riding the waves a bit more and go over them instead of under them like in take 2. Maybe a combo of the two would be best, have a bit of the wave go over the bow but not so much that it looks like the sub is duking under the wave like a surfer.

As in aerodynamics, 'Roll' is the side to side movement, not 'Pitch' as you seem to be refering to it. Pitch is the movent from bow to stern. Like when you dive nose down. I would like to see video of a stationary Sub, Pitching & Rolling in the swell, before I vote on which configuration I prefer. This is good work though. The physics of surface vessels is something that's never been great in SH4, especially the sub that appears to travel on rails like the shark did in Jaws.
