[1.12.x] Waterfall - a framework for continuous, mesh-driven engine effects (October 9)

[Nertea]

KSP 1.12.x   Waterfall [0.10.3]  Last Updated October 13, 2024

I make a lot of engine effects, particularly for vacuum engines, which are really poorly handled by a traditional particle system, much less the gnarly butchered version of that system that KSP provides. Smokescreen helps, but when we're talking about really large, fast moving plumes, the number of particles you need to create high fidelity effects is really high. Performance gets low. To that end, I and some others (primarily @Nessus_ and some porcine aviator dude who shall not be named) have created a cool new way to create and drive engine effects. 

Project Goals

• Design a framework to create mesh-driven engine effects for smooth rocket plumes
• Support for atmospheric expansion and all kinds of dynamic effects
• Cross-compatible with SmokeScreen for adding smoke effects
• Ingame editor to create and drive effects. 
• Provide a set of template effects for modders to use on their engines. 

Please note that this mod is a framework  it doesn't change anything or provide anything by itself, but provides the ability for you to do things.

Screenshots/Videos

Here's a few screenshots and videos from development over the last few months (credits to @Nessus_ and @DylanSemrau )

Templates

A lot of preconfigured templates are available for anyone to use. These should cover most chemical engines in most mods. 

How to Use

Documentation

I wrote documentation. Read it! This is a work in progress and I have a bit of trouble keeping it up to date with new features that are added weekly. If you're having issues please review the thread and ask here.

Ingame Editor

To design plumes, you'll have a pretty fully featured editor to work with. It exists in the game.

Supported Mods

You need configuration packs for this to do anything. Currently there are only one; other mods will likely ship configs for this. If you release a mod that supports Waterfall you can let me know and I'll add it here. 

• WaterfallRestock: Provides patches for most Restock and Restock+ engines. This requires Restock. 
• Near Future Technologies: Near Future Propulsion, Spacecraft and Launch Vehicles provide Waterfall configs
• Kerbal Atomics: Full support
• CryoEngines: Full support
• Far Future Technologies: Full support
• Stock Waterfall Effects: Provides support for stock

This looks insane! You've genuinely just reinvented KSP's plumes

Plumes will never be the same again, thats for sure.

[KeaKaka]

This is absolutely INCREDIBLE! 

[Starseeker]

This looks incredible!! Are you planning to add this functionality to Cryo Engines, Kerbal Atomics, and/or Near Future series engines?

[HB Stratos]

This is crazy! Will we also get integration for jet engines and their afterburners? This would be so damm cool, what an awesome mod!

so are we going to make every plume ourselves or are there going to be dev made plumes but we can change them. or like EVE with different configs

there can be pre-made templates that can be easily applied to engines via patch

Cool, I don’t want to make custom patches for each and every engine

Oh, quick question: how does this interact with timewarp? With realplume, the plumes "stretch" back during physics timewarp; I'm assuming that the methods used here prevent that?

Correct, there's no difference in time warp

I can't wait to see this in restock

Jesus christ this looks amazing

try it!

question: what if you have both realplume and waterfall installed? Since waterfall is very new and need some time for adoption, can part dev use waterfall instead of realplume when both detected with mm patch?

Porcine aviator dudes are the best! Man, there's so many good people who've had such a good influence on this game.

That is up to the developer, I'm sure clever MM can account for both.

Zorg helped define the spec, he's involved in the project.

Eventually, there's a really large amount of work to do that though. I can say that this runs all the plumes in FFT. 

[Rodger]

I made a Hall Effect plume with a custom mesh too:

this is certainly nice  

 

 

[moar ssto]

Can it support plume-plume interaction for multi nozzle engines? I realy hope it can.

Oh, is it actually ready for use? Even better

[WarriorSabe]

Is there no Waterfall for the Kickback or did I miss something on installation?

only 5 engines atm, vector, ion, nuke, mainsail and poodle

Ah, I see. Well, my Moraine II and to a lesser extent the Precipice II should notice, I've got a couple launches of the latter planned for my current mission

[HB Stratos]

I'm trying to make a MM patch to generate effects for the panther engine, but that's making troubles as it is a engine that can switch between two modes. Could someone help me write a MM patch that allows me to make effects for both dry and wet mode of the engine?
