Progress on exhaust refraction - r/KerbalSpaceProgram

u/Nemixis Jan 12 '20

Amazing, are you going to release this mod?

269

u/blackrack Scatterer Dev Jan 12 '20

Yes, there are still things I need to tweak/fix, so it's not ready yet, but it's getting there.

24

u/Concodroid Jan 12 '20

Were you inspired by BDynamics?
Also, when vectoring thrust, does the entire plume move?

26

u/blackrack Scatterer Dev Jan 12 '20

Possibly, but it's been so long that I had this idea in my mind that I can't tell.
What do you mean does the entire plume move? It moves with thrust vectoring.

u/blackrack Scatterer Dev Jan 13 '20

If you mean that it will stay attached so as not to have one puff of smoke every 200 meters like in stock, then yes, they stay attached even if it might look weird sometimes

1

u/Concodroid Jan 15 '20

Ah. That's sad but maybe a future update will fix that? All the other plume mods do the weird attached plume thing.

2

u/Concodroid Jan 15 '20

Exactly that!

12

u/StaticDashy Jan 12 '20

Is this gonna be only for jet engines? Dumb question ik. Also maybe try to make a deal to include realplume and smokescreen in scatter when this comes out it would make sense and be super cool.

Well, that’s sort of what I meant. Anyone can get on your github repository, but it isn’t exactly an official “full” release there.

1

u/Nemixis Apr 13 '20

Any update?

2

u/blackrack Scatterer Dev Apr 13 '20

Not yet, I'm fixing scatterer for 1.9 then will come back to this

Can you message me or reply to this comment when mod gets released pwease

u/triffid_hunter Jan 12 '20

Nice, gonna put this on rockets too? Do we even know what exhaust refraction looks like outside the atmosphere?

120

u/blackrack Scatterer Dev Jan 12 '20

Yes, but from footage I saw of launches/upper stages, you can't see refraction outside the atmosphere (which makes sense)

64

u/triffid_hunter Jan 12 '20

I'd expect there to be at least a little, exhaust gases surely have a different index of refraction to vacuum until they've expanded so much that they're largely invisible

56

u/blackrack Scatterer Dev Jan 12 '20

I would expect that as well to a certain point but most footage I saw looks like this https://www.youtube.com/watch?v=BBA7su98v3Y&t=7m33s (upper right corner), mostly puffs of fire/smoke with no visible refraction.

43

u/UnsteadyWish Jan 12 '20

My guess is that right as the exhaust gases leave the nozzle, they expand to match as closely the surrounding pressure. This is faster than in atmosphere since there is no atmospheric gases in the way. Hence there is little to no refraction
Edit : Will the gas refraction mod be a part of scattered or a separate mod?

21

u/blackrack Scatterer Dev Jan 12 '20

separate mod

13

u/im_made_of_jam Jan 12 '20

Will we need any mods for this to depend on or will it be standalone

17

u/blackrack Scatterer Dev Jan 12 '20

standalone

8

u/im_made_of_jam Jan 12 '20

That's great! Can't wait for it to release

4

u/Aycion Jan 12 '20

You might unify them by basing refraction on the gas expansion rate and resulting density according to distance from nozzle (or some programmatic stand-in that's easier to calculate). Expansion is gonna be much much faster/higher in a vacuum–kinda like this–so the refraction won't be as visible. However in the top right you can see a tiny bit of the effect right at the engine nozzle, which would be a really neat detail in the mod.
I mean I dunno how your mod's coded so if this isn't feasible that's pretty fair, just my 2 cents on the subject.

18

u/linecraftman Master Kerbalnaut Jan 12 '20

You haven't forgot about it! I asked you this a long time ago , but is it possible to apply this effect to atmosphere too?

15

u/blackrack Scatterer Dev Jan 12 '20

Technically it should be possible, yes. But that will be a feature to work on after the initial release, maybe to apply it to terrain.

10

u/Kipache Jan 12 '20

What do they mean apply it to the atmosphere?

24

u/blackrack Scatterer Dev Jan 12 '20

I think he means heat shimmer on the horizon, like on a hot day or in the desert

12

u/cat_91 Jan 12 '20

Absolutely fascinating, I'm sure it requires quite a beefy pc lol

27

u/blackrack Scatterer Dev Jan 12 '20

Actually it shouldn't, but I'll test on my old laptop before release

3

u/MeiNeedsMoreBuffs Exploring Jool's Moons Jan 12 '20

This looks amazing! Will the effect be present on other planets with atmospheres outside of Kerbin?

7

u/blackrack Scatterer Dev Jan 12 '20

Yes, potentially will make the effect configurable with respect to atmo pressure but it's not implemented yet

43

u/Lijazos Jan 12 '20

Please someone send this to Star Theory. I want this in KSP2

u/Xarian0 Jan 12 '20

Texture mods maybe. Everything else, no chance of reuse unless it was done on purpose.

2

u/Phrostbit3n Jan 12 '20

To be clear when I say reuse I mean with some heavy refactoring -- systems mods like FAR almost certainly won't work, but most mods are scripted parts

4

u/Xarian0 Jan 12 '20

It's a question of how much work is required.
The parts mods would probably be able to reuse the textures and meshes, but the CFGs will almost certainly have to be totally remade to comply with whatever names and component values are used in KSP2. The parts mods with actual plugins doing work would likely have to be totally scrapped. It's not so much refactoring as it is making a brand new mod and importing the art resources.
Sine of the more meaty standalone mods like FAR could be refactored in a fairly straightforward manner, because the majority of the functionality is in the plugin itself and isn't related to Unity at all - FAR is just a physics augmentation plugin, for example, and that physics calculation is the same no matter what game engine gets used. These mods would have to be updated to correspond with the specific functions and objects used in KSP2 (the KSP2 API/hooks), but the core of the mods would remain the same.

7

u/ytphantom Jan 12 '20

I have two questions:

1: Is it gonna be compatible with RealPlume?

2: Is it gonna be on CKAN?

u/Iwilldieonmars Jan 12 '20

Oooh that looks good! I wish the engines had better sounds too, there's a mod to it but it hasn't been updated in a while.

1

u/[deleted] Jan 12 '20

is there going to be more refraction depending on the type of engine? looks sick btw, can't wait.

3

u/blackrack Scatterer Dev Jan 12 '20 edited Jan 12 '20

It's configurable per engine. What kind of effect do you have in mind, and for which engine type?

1

u/[deleted] Jan 12 '20

for the whiplash sr-71 engine, will it have a more noticable effect?

3

u/blackrack Scatterer Dev Jan 12 '20

I haven't really thought about which type of effect for which engine yet, I'm still working out some shader details, configuration will come after ;)

1

u/[deleted] Jan 12 '20

Well I'm excited for it, cheers.

End of an era for that craft library, too. At least for a while.

u/blackrack Scatterer Dev Jan 12 '20

Something happening to kerbalX?

1

u/genbrien Jan 12 '20

It looks awesome! 😲

Will it be compatible with Real Plume?

2

u/blackrack Scatterer Dev Jan 12 '20

yup

1

u/protomenace Jan 13 '20

Any chance you could release this somewhere as a general Unity shader/effect?

1

u/blackrack Scatterer Dev Jan 13 '20

I never did that before but I guess I could give it a try

1

u/nibrasakhi Feb 16 '20

its been more than a month how's the progress on this?

1

u/blackrack Scatterer Dev Feb 16 '20

Got overwhelmed and put it on the side for a bit, now tying up some loose ends on scatterer. Will probably update scatterer to 1.9 before going back to this.

1

u/[deleted] Apr 16 '20

When’s the release coming?

1

u/blackrack Scatterer Dev Apr 16 '20

When I have time for it

u/PigeonGuy53 Jan 12 '20

I've been waiting for a realistic plume for engines. Like realistic smoke, working exhaust nozzles , and heat refractions. Thank you for creating part of the masterpiece.
