Community Tech Tree

he Community Tech Tree is a mod designed to extend the stock technology tree to accommodate many community mods in an inclusive and extensible manner. This takes the form of expansions to the current tech tree. It provides new and extended branches for command pods, thermal management, ion engines, nuclear power and propulsion, and many more useful nodes.

 

You can check out the layout and added nodes on Gliffy, though it's not always perfectly up to date.

 

You'll need to install ModuleManager version 2.6.2 or higher, if you don't already have it, in order to extend the tree.

 

The Community Tech Tree will not assign parts to mods itself, instead, it is up to mods to support it themselves. Any mod that does not support the CTT will still work just fine, it will just not take advantage of new tech nodes that are added. 

 

If a mod you like doesn't support the tree, let the author know, or produce your own patch to add support. The best way to to do this is via ModuleManager patches. Simply create an empty .cfg file to be packaged with your mod (call it anything you like, I use ModNameCommunityTechTree.cfg), and include entries as follows:

@PART[panel-static01]:NEEDS[CommunityTechTree]
{
@TechRequired = advSolarTech
}

This assigns the part "panel-static01" to the Advanced Solar Tech (advSolarTech) node, and will only run in the presence of the Community Tech Tree. A list of new nodes and additional details can be found in ForModders.txt, which is included in the download.

If you are a modder, you can link to this little icon if your mod supports or bundles the CTT:

ABOUT THIS LISTING

This page describes Community Tech Tree by Nertea_01. The description and screenshots are the author's own, imported from their listing on CurseForge on 25 October 2026: https://www.curseforge.com/kerbal/ksp-mods/community-tech-tree

Mythiq.net hosts no files for it. The download button goes straight to the release file on edge.forgecdn.net, so you are downloading from the author's own host, not from a copy of ours.

The download count, rating and comments on this page start at zero and count Mythiq.net only. The source's own figures are not copied here — they measure a different site, and a number that cannot be checked against our own ledger is not worth printing.

GAME VERSION

Built against KSP 1.12.5. Parts and plugins compiled for one major version routinely misbehave on another — a plugin for 1.8 can fail silently on 1.12.

DEPENDENCIES

Many part packs and plugins depend on ModuleManager, and some on each other. KSP's loading log (KSP.log in the game folder) names the missing dependency when a part does not appear; the author's page lists the usual set.

1. Download the archive with the button on this page and unzip it.

2. Move the mod's folder — the one containing the .version file or the part folders — into:

Kerbal Space Program\GameData

The path in game must read GameData\\…, not GameData\\\…

3. Start the game. Parts appear in their categories in the VAB; plugins show their own toolbars or settings screens.

4. If the mod ships a CraftNote or extras folder, leave it — some packs store example ships and textures there.

UPDATING

Delete the old folder in GameData first. Two versions of one plugin loaded together is the usual cause of duplicate parts and toolbar errors.
