How do you add custom parts to the tech tree?

[SergeantBlueforce]

I have a parts addon that works fine in 0.22 but it's not on the tech tree (for obvious reasons), so I want to know how to add parts to the tech tree (I assume it can be edited through something like notepad++)

Install the mod as normal. For each part involved, you need to crack open the configuration file and add these lines to the parameters:

TechRequired = start

entryCost = 0

Put these just above the "cost" parameter - I'm not sure the exact placement is necessary, but it at least keeps things cleaned up.

Once that's done, fire up KSP, go into the tech tree and activate the part (click on Starting Tech and then click on the part's icon). That should do it.

That reminds me - I installed Protractor the other day and still need to update the parts so I can use them in career mode.

Incidentally, if you want to set it up to where it's available later on down the road, find a part that becomes available with the unlocking of the desired technology, open up its .cfg file and take a look at its TechRequired parameter. Then for the part you want to add, instead of adding TechRequired = start, you say TechRequired = {same as the other part.}
