MechJeb in Career Mode - Out of Date, Use as Rough Guide Only
By Bajeej {R}
This is a short guide outlining where aspects of MechJeb are unlocked in the tech tree of career mode as of Version 0.22. It should continue to be accurate beyond 0.22 as long as
a) the file structure of the game doesn't change and
b) mechjeb doesn't switch the positions around in an update.

Please rate this guide if it was helpful, and check the comments for additional info.

The Tech Tree
MechJeb controls are split up among multiple parts of the the tech tree.


Important information: If you have been playing the game and have already researched these techs before installing mechjeb, you won't experience the benefits of mechjeb. It's weird, but the solution is simple - just research the previously researched techs again, it may indicate a cost, but it will be free and then mechjeb will be enabled.

  • Custom Window Editor

Troubleshooting
This section contains fixes and and answers to questions I found in the comments. Be smart about which solution is best for you, and if you find a better way please post it in the comments.


  • I've re-researched the parts, but MechJeb still won't show:

    Try deleting 'Mechjebs settings global in C:\Program Files (x86)\Steam\steamapps\common\Kerbal Space Program\GameData\MechJeb2\Plugins\PluginData\MechJeb.

    if this doesn't help, you may have incorrectly installed mechJeb.
    (Navigate from your gamedata => MechJeb folder => "Plugins" => "PluginData" => 'mechjeb_settings_global')

  • I clicked on the research group but I still don't have the Mechjeb tech:

    Click on the Tech Group icon, then go click on the individual mechjeb tech that appears in the right-hand window. Click the research button.

  • Do I have to unlock Mechjeb in Sandbox mode?

    No.

  • I unlocked the Mechjeb part, but many of the options are greyed out in-flight:

    You unlock the Mechjeb part early on and the part never changes, but the features will get unlocked (not greyed out) as you research the new mechjeb technologies, they're not all immediately available.

Installing MechJeb 2.12 a fair bit into a KSP 1.11.1 play-through: I got the MechJeb parts without me having to re-research any of the old tech. :KSmiley: :steamthumbsup:

A LITTLE SPOILER!)

Want to use ascend module before research in tech tree? Use it from script module!

@CaraRota Glad you found a solution and thanks very much for posting it here in the comments so others can find it if they run into trouble.

Well Thinkpadius, i really appreciate your quick response. But im happy to say that i found out the issue; you need to upgrade your mission control and the tracking station, and et voila! Problem solved!

Thanks again for your time!

@CaraRota - at this point I'd say that this guide may be very out of date. I haven't updated the guide since version 0.22 which came out a couple of versions before version 1.0. So I'd use this guide with a grain of salt from now on.

Got a question here please
it says

" It's weird, but the solution is simple - just research the previously researched techs again, it may indicate a cost, but it will be free and then mechjeb will be enabled."

how do you " just research the previously researched techs again"?
