HOW TO INSTALL ON 1.0.5:
Since everyone's asking for it, here is the way I did it.
Download the version of Kerbal Konstructs from this post here: http://forum.kerbalspaceprogram.com/index.php?/topic/94863-104on-hold-kerbal-konstructs-v0950-105-broke-it-i-cant-fix-it/&do=findComment&comment=2329126
Delete the old version of KK, and replace it with that one.
Now, create a new file in your GameData folder. Name it kerbinside.cfg.
Paste this code into it:
@STATIC[*]
{
concaveColliders = all
}
That got everything working perfectly for me. Credit for these goes to Thomas P, you could have found all of this info by looking a couple pages back in this thread.
