[Solved] Unity and PartTools problem.

[Enceos]

For some bizarre reason PartTools stopped working in my Unity.

I spent 3 hours at least trying to figure out why and what happened, even reinstalled unity, no result. My work on modelling is stalled.

Simple process, I'm creating an empty project, dragging PartTools folder under assets, after everything is imported I'm going to either Tools>KSP Part Tools or a Part Tools component under an empty GameObject. When I'm setting the GameData directory unity throws two errors and hangs.

Can anybody decode what's happening here?

Try pointing it to a fresh KSP install? Looks like it might be freaking out over a corrupt or incomplete config somewhere as it tries to pick up stuff in the database.

lo-fi, you're my hero ) I didn't even suspect KSP install was bad

You're very welcome with the logs complaining about config nodes, it had to be KSP related. Happy to help!

If you look through KSP's log after it's loaded the parts you may even find the specfic culprit in that install. Part Tools' error handling isn't all that, so doesn't take much to make it say "no". Might just be an incorrectly formatted config file.

Steam made a mistake somewhere while updating to 1.0.4. Checking file integrity didn't solve the issue, had to make a fresh install.

OMFG Thank you!

I just spent 2 hours pulling my hair out and yelling at my computer! Then I found this post.

May the RNG Gods bless you and give you some of that sweet sweet internet karma!
