hmm, seems it's not just Venus that's a moiréed yellow blob, most of the planets are like that :(
<soundnfury>
and the one that's fine, Vesta, has all .png and no .dds, suspicious...
<awang>
Apparently random loading errors due to ModuleRCS throwing exceptions can cause satellites to vanish permanently :(
<soundnfury>
Pap: is there anything I can do to help debug this planet rendering bug?

damn, had FAR's assistants on in vacuum, that was messing shit up
<UmbralRaptor>
a few atoms per ml at best tends to make for annoying aerodynamics.
Rokker is now known as RokkerSleep
<xShadowx>
ml? ul
<UmbralRaptor>
ul?
<UmbralRaptor>
ml as in cm³
<awang>
Hmm
<awang>
Because FAR abstracts away airfoil shape
<awang>
Does that mean that a plane's vertical stabilizer would actually produce a net sideways force?
<awang>
Since it would be treated as a sideways wing?
<awang>
ferram4: ^?
<ferram4>
No, because FAR abstracts away airfoil shape.
<ferram4>
Zero-AoA lift is a factor of airfoil shape.
<awang>
But aren't wings treated as if they were airfoils even though they look flat in-game?
<awang>
So shouldn't a vertical stabilizer produce lift still?
<ferram4>
If at an AoA, yeah.
<ferram4>
That's how vertical stabilizers work.
<awang>
Right
<awang>
But would a vertical stabilizer in FAR still produce lift at 0 AoA?
Orkeren has quit [Quit: No Ping reply in 180 seconds.]
<awang>
The way I'm thinking of it is as if I took just the left wing of a normal airplane and rotated it so it pointed upright
<awang>
Er, and changed the dimensions so it made sense
<ferram4>
No, because FAR does [i]not[/i] model zero AoA lift because that is purely due to airfoil shape.
<awang>
.....Uh
Orkeren has joined #RO
<ferram4>
Remember that AoA is measured for any wing relative to its plane, not to the vehicle as a whole.
<awang>
I thought FAR treated wings as a NACA 6a series airfoil or something?
<ferram4>
Symmetrical ones.
<awang>
Oh
<awang>
That'd explain it
<awang>
My bad then
<awang>
I'm just seeing a non-zero SideForce reading in the FAR flight data window when flying with 0 sideslip and was wondering where it was coming from
<awang>
Thought a nonsymmetrical vertical stabilizer might explain it
<blowfish>
apparently KSP has some weirdness as to how it calculates joint strength for surface attached parts which results in asymmetric joints on parts attached with symmetry
<awang>
wut
<awang>
That's certainly unexpected
<blowfish>
wut indeed
<awang>
Only KSP could make symmetry nonsymmetrical
<UmbralRaptor>
That's still not fixed?
<blowfish>
I haven't heard anything about it being fixed
<UmbralRaptor>
stabbity
<awang>
Didn't know that was a long-standing bug
<xShadowx>
how many of squad are still squad that have been squad since like the start? :|
<taniwha>
I thought it was fixed for 1.2
blowfish has quit [Quit: Leaving]
<awang>
Uh
<awang>
I'm not sure how to word this
<awang>
Do planes trim up or down?
<awang>
So like in KSP, when setting trim
<awang>
Do planes normally trim as if they were constantly pulling up or nosing down?
<awang>
In level flight and/or cruise, that is
<taniwha>
depends on the plane, I imagine
<taniwha>
and conditions
<awang>
Do engineers try to aim one way or another?
<awang>
It may vary by plane, but I'd guess that that would be a parameter that engineers would at least experiment with?
<awang>
How uniform are conditions during cruise anyways?
<awang>
Barring flight into areas of really heavy turbulence
<taniwha>
cruise? fairly uniform

How much does the vertical location of the center of lift (center of pressure?) relative to the center of mass matter?
<awang>
I know for sure it needs to be behind the CoM
<awang>
But how bad is it for it to be slightly below the CoM vs above?
<awang>
Also, what distance between the two should I be aiming for?
<awang>
Approximately?
<taniwha>
awang: CoL above CoM gives roll stability (for subsonic, at least)
<taniwha>
awang: think of it as grabbing the plane by the CoL and how the plane wants to dangle from a pinch-hold (ie, one where the hold itself induces no torque)
<taniwha>
CoT affects it too, of course
<taniwha>
but once you know how your plane wants to pitch based on those three, you know which direction you need to trim to maintain level flight

is there any way to debug contracts from sandbox mode?
<lamont>
or is the general method used to create a career save with piles of money and science up front and all the sliders on maximum easy mode and then just unlock the tech and contracts you need?
<Bornholio>
you can cheat complete active contracts until you get to the one you want to run
TM1978m has quit [Remote host closed the connection]
<schnobs>
lamont: the cheat menu provides convenient and quick means to provide you with all tech, all facilites and so on.
<schnobs>
If you only want a subset it becomes busywork, though.
<lamont>
yeah the debug menu for contracts seems to be disabled in sandbox though which was really what my question was about…
<lamont>
so just start a new career save and cheat your wat up to the point you want to test then...
<schnobs>
ah... now, won't work. You can turn career into a defacto sandbox, but that's it.
<Bornholio>
I din't see a way to enable contracts in any form in catbox when i tried
<lamont>
cool
<lamont>
ah, and i’ll have to look for those buttons schnobs...
<lamont>
because, yeah, i don’t need a subset of tech...
<Maxsimal>
if you're just trying to debug something besides contract criteria, you could temporarily comment those out
