[1.8.1] ETT - Engineering Tech Tree - May 4, 2020


Recommended Posts

ETT is a pinwheel design that is grouped into branches of related engineering disciplines.

TechTree.png?dl=1

Premise

Do the Kerbals discover rocketry before winged flight? You decide. Both winged flight and rockets first options.  ETT also has an "End Game" so you can play the campaign game with a built in goal.

I love to hear new ideas and don't be afraid to let me know if I have a part or two out of place.

Listed on CKAN or Download at SpaceDock - May break saved games.

(May 5, 2020, 02:12 PM CST - SpaceDock may be having problems so here is a temporary link: https://www.dropbox.com/s/m7c1pw83jqssmki/ETT20200504.zip?dl=1)

REQUIRES:

Scope

A tech tree based on engineering/scientific principles... mostly, that is challenging to unlock yet fun to play through.

Goals & Requirements

1. Branches of the tech tree based on engineering disciplines.

2. The Kerbals discover rocket powered flight before they figure out winged flight. (or vice-versa)

3. Unlocking the entire tech tree is not required but must involve flights to nearby planets.

4. Parts that generate science are spread throughout the disciplines and are not based on which branch you focus on (e.g. Flight, Liquid fueled, Solid, Exotic).

5. The player may unlock just the branches that they are interested in.

6. "End Game", so you can play the campaign game with a built in goal.

Highly Recommended for FLIGHT FIRST option:

  • Breaking Ground, Firespitter, SXT and/or KAX for propeller parts.
  • Take Command to use the external command seat for barnstorming... I mean science.

Highly Recommended for ROCKETS first:

  • Interstellar
  • KW Rocketry
  • MRS
  • SpaceY
  • BDB
  • FASA

Recommended for the tree overall:

  • Kerbal Engineer or MechJeb for delta V calculations.
  • DMagic Orbital Science to boost your science output. @DMagic

You can play this tree completely stock, but I wouldn't recommend it.  I believe it is the most fun with several part packs. The many nodes of the tree limits the amount of parts that show up in the editor which makes it easier to find the part you are looking for.

There is a lot to be updated.  Hopefully most legacy parts in a part pack won't need to be moved.  I will start with the part packs that are updated for the latest KSP rev.

Next Revision:

  • Update to 1.9.1
  • Enable Part Upgrades
  • Better stock part placement depending on which mods are installed.
  • Re-integrate Interstellar, KW Rocketry, SpaceY, Luciole, and the remaining Near Future part packs.
  • If someone re-releases LLL (Lack Luster Labs) I will re-integrate it also.

Thank you @linuxgurugamer for fixing the YongeTech software I was using.  Also, shout out to @GrubbyZebra and all those who helped keep ETTR alive while I was away.

There is still a lot of work to do, but I thought I would release what has been done so far.  Part upgrades still require integration.  A version for 1.9.1 should be out soon.

Thanks to all those who have helped me get this far, @yongedevil@troyfawkes, @NathanKell, @Artfact, @Bahamut@inigma

@odya-kun, @SpaceNomad, @GrubbyZebra@linuxgurugamer

Kerbalstuff says this is on CKAN but i cant spot it??

I just finished the CKAN process. It should show up there shortly.

Is there also a branch to start with unmanned rather than manned for rocketry?

Yes. You have your choice. Rocketry starts unmanned and can stay unmanned or you can also do manned missions by unlocking that node and progressing down that branch.

Okay, took me a while to realize (actually until I had unlocked Electrics and wondered where the solar power node is) that this mod needs Module Manager 2.6.2 or newer. Works like a charm now. Thanks for all this work you've put into it.

I had a really good question this morning and I thought I would share it here:

I was wondering if you had a list of all the mods required to have as few empty nodes as possible?

Good question. I play with a 64bit version of Linux so I don't have to worry about memory problems. You might want to be careful though.

Here is a good start:

Interstellar (which prompted me to build this tree in the first place)

FASA/FASA launch clamps

Infernal Robotics (and additions)

Dmagic Orbital Science

Near Future Solar

AIES (patched) - I trim this one down just to the parts I want. Same goes for my FASA parts.

MRS, SpaceY Heavy Lifters, KW Rocketry and/or Behemoth Aerospace Engineering (I usually play with only MRS and SpaceY because BAE is pretty new)

Station Parts Expansion

On the aircraft side:

Firespitter

(soon to include KAX)

Right now I am working with another modder on the Aviation side. I had to rearrange it due to the 30 part limitation of the SPH and we are not happy with it yet. So look for changes there.

Right now I am working with another modder.

So yeah, I'm the other modder. \o/ We have started working on reorganizing the file into seperate files based on tech branch, ie: rocketry, aviation, etc. I've also begun integrating a few smaller mods unto the tree.

Wow, this looks fantastic, and I really want to try it with KSPI. I'm using CKAN, and already have KSPI Extended, and the CTT. However, CKAN won't let me install the Engineering Tech Tree because it says it's incompatible with the Community Tech Tree. Any way around this?

CTT is an option for KSPI. When you go to install KSPI just leave CTT unchecked. Or just download ETT from KerbalStuff. ETT was originally created for KSPI and is designed so that it will over-ride CTT's setting making it redundant.

Thanks for letting me know. I will check CKAN's settings.

That seems to have worked. thanks. Am starting it up now. What about the interstellar upgrade nodes, will they still work?

They should, if I did my module manager files correctly. I moved them about and tested one of the upgrades and it worked. I need to create a small wiki that shows the upgrade nodes for interstellar and Mechjeb. Currently Mechjeb functions fully when it is unlocked. That is going to change though.

I gotta say I love this tech tree. I used to use the adios tech tree but it wasn't updated. I do have a problem unlocking atomic power it says I need electrics but I have that already. I looked through the cfg file and it seems to ok. any ideas?

May I suggest starting from the left, then organizing different paths by sorting them by line? This three is nice but the layout is confusing :)

I agree altrue, unfortunately the original tree was built using an old old mod called tree edit. Which means that every node I want to move now, I have to manually type in the x,y coordinates. If I have time I will try to convert the node portion of the tree to a database so I can automate the process a little more.

Ah. You probably need to spend some funds upgrading the Tech Center. You start campaign able to unlock nodes less than 100 tech point nodes. 100+ Tech point nodes for the first upgrade. 500+ Tech point nodes for the second upgrade. I made the Modern Physics technology branch difficult and expensive on purpose, like it was/is in real life.

ok makes sense why there are a lot of nodes that need only 95 but lvl1 RnD says research limit 100. shouldnt that mean that it can be up to 100 not anything under 100? anyway thanks for the help. now i gotta save up that 902,000 to upgrade lol (hard mode)

Intresting, does that mean your mod includes all technodes used by KSPI? This is important a lot of KSPI-E balance depends on it. For Example, the plasma thruster is affected by 3 techs. One tech to unlock the Basic plasma thruster, one tech to unlock Variable Isp and the last tech to unlock Quantum Vacuum.

That is gonna be quite challenging. Make sure you hold out for some long term, high initial payout contracts, that way you won't have to grind for the funds.

It should unless I missed something FreeThinker. I have changed the unlock upgrade tech nodes to align with the engineering tree, but its all in there. I will make a chart to show the ETT equivalent unlock upgrade tech nodes.

I have found an issue - for some reason after researching the prerequisite tech for nuclear power - nuclear power is still unavailable for being researched

You may need to unlock the Research and Development Center an additional level. I made the Modern Physics branch quite tough as it is in real life.

ok thanks for the feedback - now that i think about it that is kinda logical as it is also on the level 1 r&d's research max limit.
