Nertea

Lots of opinions here to unpack! We have to walk a fairly fine tightrope when choosing to represent the complex reality of real rocketry. For a lot of historical space applications, a specific need was often defined (go to the moon), which drove the selection and development of all components of the spacecraft, including choice of fuel(s) and development of the engines (from scratch, from a study, or upgraded from a previous vehicle). With KSP, we're kinda working backwards - we get to make guesses like "here are the missions we think a player will want to do" and strive to provide a set of engine options that let them do that. That's a pretty big space - players want launch engines, space engines, efficient engines and such for their missions. Filling that need for even a single fuel type requires a lot of engine parts. There's 20 in KSP1 and there's sill frustrating gaps to me. I do like playing Engine Selection Simulator myself, but providing enough options for player flexiblity with several liquid fuel types causes the number of engines to go up fast. I should know, I made at least one KSP1 mod for that. Approachability in this space is a huge problem too. New players end up with a lot of confusion over parsing through even the basic set of engines. More engines that use different fuels create more approachability challenges, particularly when trying to match them with their fuels and understand when to and when not to use them. That's a teaching challenge we have to bite off with our later, fancier engines, but there we have the advantage of being able to use fairly unique models and well-defined, different performance envelopes to do that. All this is why we are effectively sticking with a single liquid bipropellant engine resource, at least at the beginning of Early Access. There's a long road ahead of us though, and room for a lot more things! Of course - like Nate indicated, you will see hydrogen for use in nuclear engines at EA launch as a new fuel as well as the old standards like Xenon. There's lots of good discussion about methane as a base fuel in this thread, with some strong pros and cons. I'm always encouraged to see that these matched our internal design debates and I believe that we've made the right choice. Think of it as Kerbals taking a slightly different technical path to rocketry than humans. To quickly reiterate, we're not rebalancing our engines to be considerably different just because they use methalox or anything - you'll see craft with the same engines behave more or less the same in KSP1. All the above being said I immediately expect modders to do what modders do, and show up very quickly with mods that add, for example, the 150-odd resources in the Community Resource Pack into KSP2. And mods that change the engines that look something like hydrolox engines to use hydrolox . Modding is great!

I haven't changed that code in years, you'd have to ask the other poster and compare conditions.

You can see what I'm doing here: https://github.com/post-kerbin-mining-corporation/StationPartsExpansionRedux/blob/f0c03675c817782d99c3e919c1e30d070f8a360b/Source/HabUtils/ModuleAdjustableLeg.cs#L156 It's not very groundbreaking and I'm honestly surprised it works as well as it does.

The two mods are fundamentally different in how they handle everything. A compatibility patch is changing all of one mod to fit the other and that's not something I'll ever make BDB team asked for some features and I have a good relationship with the devs .

It's really hard to maintain such a list so no. I know BDB has good support I guess? I have no idea what I'm supposed to be looking at. This seems unlikely because I manage that myself and there's no issues

Probably scatterer TAA.

System Heat 0.6.0 Most UI fields now report in SI-prefixed units for flux (W, kW, MW, etc). This is not (yet) true for all modules though. Added new functionality to cool fuel tanks with radiators and the SH system Added optional patch to apply this to CryoTanks Added some guardrails around the handling of Kopernicus planets that might have inconsistently configured atmospheres Added ingame settings. The following things can be customized per game Boiloff: enabled and scale Nuclear fuel transfer: require engineers, what level Fission reactor damage: allowed, various tuning variables Fixed engine heat for VASIMR argon modes Support USI reactors Fixes to universal harvester patch

You don't have to do anything, as far as I know. Every tank that is touched by the mod is allowed to have cooling, the non-ZBO ones are just disabled by default. Click the PAW option to turn them on.

I'm retired, I work on what I want when I want.

I managed to cook my modding computer but it's back now. Some pictures of the process for the 2.5m reactor. Looking at the old one, going to try to preserve some of the silhouette because it is dear to me Gotta keep the look unique compared to the 1.875m one. Components blocked out. Getting to a coherent external detail level. Rolling in the machinery and pipes, nice lineage with the 1.875m reactors, but showing off some size optimizations and more turbines.

Something put a badly configured DischargeCapacitor module (part of Near Future Electrical) in those parts, which broke them, which in turn broke this mod. Likely it is ODFC. I seem to recall some kind of similar bug ages ago with it.

Another option is to open up the debug panel and turn the heat generation slider to 0. This should affect SH parts and make them produce no heat. Thus invalidating a TON of development and balance work :).

This is an intentional 'bug'. You have command all the time because it is a probe core. Also because it's a probe core, it has to be powered. There are no radiators with NFE. Reactors are totally compatible with existing radiators out of the box, it won't even take a ton. They just will not be very efficient. Missing implies I ever did any. Never got around to it.

I think you're missing a pair of curly boys there.

There is a patch in Extras that switches the fuel types but it isn't dynamic.

Adding the 1.875m reactor to the list.

Waterfall 0.9.0 Significant stack of performance updates that should increase performane significantly on ships/templates with lots of effects (big thanks to @Al2Me6, @DRVeyl, @JonnyOThan) Fixes to Additive Volumetric shader including fix for atmosphere sorting at night sans scatterer

I can neither confirm nor deny the presence of an internal betting pool for ranking speculation posts. Glad you all like the part! As many of your have remarked, there's a lot of F-1 heritage here in tribute to one of the most famous rocket engines of all time (I'm sorry RL-10, you came in a close second ). This is mixed with some detail inspired from newer F-1 development and surface treatments that draw from modern booster engines that Jonathan has really used to great effect. I'm glad to see people commenting on the beefy, powerful feel - we want our booster class engines to reflect their stats and are developing a distinct visual look for them.

Need a test case.

I mean to be really clear I'm not coming back. I'm just trying to clean up this half finished project. The exact shape of the release is yet to be determined. I haven't decided whether it is best to actually release this as a 'new' mod and keep the legacy one around separately, or deprecate and retire the old parts. Regardless, there will be some pathway to updating with an in-flight save.

You get it by downloading the dev branch from github - there's no specific release package. Slowly polishing the tiny reactors up.

Evaluating the dev version is fairly useful to me.

Huh. No that looks right... I'm kinda confused though - did you solve it?

Honestly in fact I would really love to release the reactor stuff eventually so we'll see if I can summon the motivation to complete it eventually.

I'll look into it when I have some time.
