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

[Starseeker]

Alrighty, lemme generate a new log (since I loaded up a different install since).

Here it is: https://drive.google.com/file/d/10NV7QINpaK8wkVDUSPEsmDOpklLnoM1v/view?usp=sharing

Hello all. Nertea, I would like to highly commend your art work and thank you and your team of fantastic contributors for maintaining a series of mods I have used since I started playing KSP a few years ago. If I had a background beyond SOLIDWORKS and PLC programming I would want to know how I could contribute, however, I digress. I was re-entering Kerbin earlier today at a fairly high velocity (restock inflatable heatsheild deployed) feeling a pang of disappointment not only in the performance hit I was experiencing given my fairly beefy laptop, but also the quality of the reentry particle effects themselves (I do have “5reentry particle effect” mod installed that does help visually and it is worth noting my visual mods list surely contributed to the performance hit). As I am a regular reader of these forums (have not posted much as I have nothing of value to contribute) I became aware of waterfall and was quite impressed. I am not sure how heatsheild particle effects are generated in comparison to engine effects, however, if they are similar would it be possible to use waterfall to fill this roll? In your opinion, are the  capabilities of waterfall (assuming it could even be used for these effects) adequate for replicating  reentry heating / plasma trail? If so, what resources are available so that I could possibly explore this and potentially  contribute? 
  Of course, if it is not possible then please disregard, apologies for the long winded and off-topic question, and thank you again for truly enhancing what I already consider my personal favorite game. Cheers.

I couldn't work it out from the log so it'll have to wait until the modding computer gets back. It's weird that the template doesn't work on one particular engine but works on others (that was implied from your statements).

Hey that would be pretty cool, but it's a completely different problem. The re-entry flames involve procedural generation of trail meshes that conform to the craft shape, which is pretty performance intensive. I'm sure it could be done better (most things in KSP can be), but it's not something that this solution would help with.

Ah yeah, sorry, should probably have been more explicit on that: it's working perfectly fine on all other engines I've applied it to.

Is there another engine in the stock/ReStock+/CryoEngines that has multiple independent thrust points like the Tharsis? I could try applying the template to that engine, see if it has the same error.

Well, I'm pretty sure it's not the multiple thrust points, considering that the templated FX works for the Poodle, Twin Boar and the Ursa. It really seems like something more subtle. 

Can you post your template and your template application patch maybe?

Yeah, here's a Google Drive folder with the two:

https://drive.google.com/drive/folders/10rV3hyrE-wntLpCKaMBn6GjlS2Wouubk?usp=sharing

cryoEngineTharsisWaterfallFX.cfg is the application patch, and starseeker-hydrolox-rl10.cfg is the template. I also added the application patch for the Hecate (cryoEngineHecateWaterfallFX.cfg) to use as a comparison.

Nothing immediately obvious but I'll keep these to look when I get a chance. 

[Starseeker]

Oh, one thing that might have to do with it: should the engineID = basicEngine line instead be engineID = Tharsis?

Nope, that should map to the EngineID in the ModuleEnginesFX. If it doesn't match, it will fall back to 'first engine' without any issues (and the log will definitely tell me if that is failing).

Laptop's back, I found the bug related to this, I will be issuing a new release soon. 

[Souptime]

Question: Do i need to make custom plumes or does this remake current stock plumes?

It redoes a handful, but for the most part it needs to be configured

[Souptime]

So i need to make then configs for it to work?

For most engines (at least outside of a couple external mods that may have updated to use it), yeah. There is an ingame editor though, so you only need to set up the basic frame of a config, then you can go ingame and edit it visually.

Gotcha! Hopefully it's an easy fix!

Darn, i dont know how to write configs for poopoo. Guess i gotta wait for the mod to update

[Nertea]

Small updates

•  Fixed a number of bugs related to the Material Editor and new effect creation
•  Fixed Color Modifiers not working on multi-engine setups
•  Improved behaviour of Transform effect blending modes (still not perfect but eh)

[WarriorSabe]

I was going to start making some configs of my own for the engines I was using, and I noticed something: your Mainsail patch modifies liquidEngineMainsail_v2, but the actual Mainsail engine seems to be liquidEngine1-2. That's the only one I can find in the Squad folder, and only the latter shows up in my .craft files.

Edit: I just realized I'm on 1.8 and v2 is probably the 1.9 (or was it 1.10?) one, never mind

Alright, I'm actually going to start making some configs now, but there's some stuff I can't find on the wiki. What are each of the models and materials, and what do I use for what? e.g., which one do I use if I want mach diamonds or what have you?

Also, how do I remove the particles from the Cheetah? It has no EFFECTS node

Edited September 4, 2020 by WarriorSabe

[Starseeker]

Alrighty, can confirm that the update fixed the issue on the Tharsis! (It's on the very right, behind the Pavonis)

Now I have configs for everything from CryoEngines except for the Etna, which I can now go ahead with making!

The material and shader list has been evolving too rapidly for me to keep the wiki up to date, apologies. The best way is to look at example configs.

To remove effects from engines, best to look at the restock patch configs, lots of examples there as they strip them and replace them with EFFECTS based fx.

Alright, I can check those for the materials and shaders.

I had already gathered how you removed EFFECTS{} node and added a new one sans engine plume, my problem was with the Cheetah (as in, the Making History engine): it has no EFFECTS{} node to remove, looking at its config, but it still makes particles somehow.

There here

its using the old ModuleEngines you have to change it to ModuleEnginesFX

Indeed, this gets done a number of times by restock, so that's why I suggested looking there. Reliant, swivel, etc all have their old style plumes removed in patches.

Ohhh, ok. I misunderstood and thought you meant the Restock+ patch in Waterfall
