Sub Pitch Tweaking - Comparison Testing

panthercules · 11-22-07, 08:16 PM

I've been messing around with various tweaks trying to induce a better pitching motion to my sub, and I've been staring at so many combinations lately that I've begun to wonder if I'm making any progress or not. If anybody has a couple of minutes, I'd appreciate it if you could watch a couple of short videos (30 seconds each) and let me know by voting in the poll if you can tell any difference and, if so, which one you like the best:

Take 1 can be viewed here:

Take 2 can be viewed here:

Thanks in advance for the help.

I like number 2 panther, like the waves crashing over the bow especially

Bill Nichols · 11-22-07, 09:04 PM

Ditto, Number 2.

Ivan Putski · 11-22-07, 09:11 PM

No.2 does it for me.

Are you messing with the fr_ratio? I found out that throws off aiming through the "sccope" on the deck gun and have pulled it for now. You have to make additional mods so the gun scope will be accurate.

As for the videos, I'd like it halfway between the 2.

Once done, looks like it might fit in well with RFB (hint, hint)

Nope - I did for a while, but like you I realized that has some undesirable side effects so I've left that at the normal .5 value for these latest tests. (Leovampire had originally suggested using that factor, but as Leo pointed out to me in PM, it makes the dive planesmen keep the planes at odd levels to try to keep the sub trimmed front-to-back underwater, and if you go too far with it your boat actually stands on its head, so I decided to stay away from that parameter.)

one loked like the sub had mass, 2 looked like it was getting tossed around a bit too much

leovampire · 11-22-07, 11:11 PM

But #2 looks better.

Either lowered the sub's surface depth or changed the surface mass maybe?

I know as you do that fr is a dead issue to work with.

CG is almost totaly from side to side movement on the surface except when diving and surfacing as it will make the sub pitch up and down for that a lot.

The pitch in #2 looks great... like some of those Victory at Sea type clips. The roll in both looked a bit too fast however.

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.

Too much listing port and starboard .

Like i already mentioned in the ROW topic (page 54 post 1080) with this pic for a example ...you could ad to the pitchfeeling by increasing the bowsplash when you are surfaced in 14-15 m/sec (highest values in sh4) conditions IMHO.
Just look at this pic and you can see (almost feel) that there are some huge forces involved here.
This could help simulate pitch maybe from another angle..without too much touching other settings that could cause
new problemes with other settings.

I choose #2

my 2€cents

Digital_Trucker · 11-23-07, 09:54 AM

Two for me too!

I agree - I think a bigger bow splash would help a lot. Unfortunately, I have no clue how to increase that

Thanks for the input - it seems that I'm on the right track and making some progress at least. Part of my problem is that a part of me wants to see the sort of big-time, crashing-through-the-waves visuals we experienced with SH3, but another part of me keeps saying that the US subs had a higher profile and more freeboard than the German U-boats and so probably did not look the same as the German ones going through the water in these same sea states, so I have to tone down my expectations somewhat.

Also have to do some more testing at various wind/sea states to make sure nothing else is getting broken, but so far so good - the testing in the videos was in the midst of a fleet of fishing boats, and none of them seemed to be getting damaged by the slightly higher wave heights involved, so hopefully this won't suffer from the problem of ships sinking from too-heavy seas that we've seen before.

If anybody knows how to increase the bow spray effect, please let me know and I can play around with that too while I'm doing this other testing.

#2 is my pick. In seas like that the waves should be crashing over the deck and the crew turning green from the motion.
