As for the disappearance of objects below the water line, each object has a trigger in the *.dat file that may be set to 1 (visible under water) or 0 (not visible under water). I didn´t check out the smoke, but it should be the same there. Best example is the loop antenna used by GWX. Dive to periscope depth slowly and switch to external view. When the bridge is flooded partly the antenna is visible above the water line. If you move the cam below the antenna disappears, moving the cam back to surface makes the antenna "re-"appear.

Regards,
DD

I didn't mean to imply that privateer was withholding info, far from it. I was just curious as to how things work in general. :) Looking forward to the mod. I suspect it will be the second SH4 mod I install.

Excellent, thanks Captain!

@DD, Thanks my friend. Been busy in RL so I'm slow to get in here at times.

What I did to start with on adding smoke was "borrow" a section from the particals.dat
I adjusted placeing and adjusted several other areas.
This can then be placed in the dat or the sim file of each sub.
For helm control, I'll be looking at attaching this to the bow wake.
that would allow the smoke to start and stop in a more realistic way.
This type of control lies in the val file.
Again, this is all done through hex editing, as no 3d work nor image work
was done.
In the section I "borrowed", I added the visible under water tag,
as the original chunk did not have it.

Not wanting to rain on anyone's parade but smoking diesels was an absolute NO-NO. The only thing that was expected to be seen exiting the exhaust port(s) was water spume associated with water cooling. However, bluish smoke was noticable immediately upon starting of the diesels but would quickly clear. Smoking diesels indicated an engine who's injectors and crankshafts where out of synch.

But that would make a nice mod if someone could accurately duplicate the the water coolent effect.

Well, i know what i have read in"Buchheim's" book + what I have seen so far from Privateer does look awesome. If it was 100% like that or not...well for me its also the excitement of actually getting it to work (in this case Privateer) that's sooo cool when you set out to do something and you actually get it to do what you want, that's the modding/motivation drug for ya, can't give it up!

I do believe there was some exhaust smoke at high speeds. I could have sworn ive read of skippers being concerned about exhuast smoke, even during night surface runs as they skimmed past escorts.

Yes, under typical cruise conditions visible smoke was undesirable and frowned upon, but even a gasoline car from the 70s would belch out visible exhaust at high throttle settings(passing while at freeway speeds)...or even a late 90s/early 00s city bus will belch smoke at high throttle(even here in environmentally conscious California).

I'd expect a low-ball government contracted diesel from the 40s to put out a little bit of smoke at high power settings.

I don't expect the Smoke to ever satisfy everyone, all the time.
And that's cool with me.
I expect people to adjust it to suit thier tastes and actually look forward
to that happening!
Once I get a bit more work done on it, I'll include a tweak file(s) for that very
reason.

Hi Privateer,

Sorry to resurrect this one, but I was wondering if this ever got off the ground. It was looking promising...

Perhaps a more white smoke could be better, this can simulate better the mixture of sea water and fumes
