Kethane is broke for me, just gives me a backdrop when I try to launch a rocket with a scanner on. No rocket, no pad, just space. As far as I can see I have no mods that would clash with it and KSP and Kethane are up to date. Help?
I think there already is everything possible listed there - if you look under the sections for each part of the CFG you can see the code, and for each specific piece of code there's a section at the bottom dependent on part. Also, spacep00se2, that's pretty much correct. However it can be finicky occasionally; sometimes nodes aren't quite in the right place, so you have to play around a little.
Blender can't import the .dae model, I usually eyeball it. :V Here's the wiki's info on CFG editing, I wrote it myself. http://kerbalspaceprogram.com/wiki/index.php?title=CFG_File_Documentation
Kudos to you, those look fantastic! I was trying something like this myself, but had major problems attempting to UV map it so gave up. As a suggestion, I think it may look better if the attachment pylons were slightly lower down and if the nacelles were a bit thinner, but otherwise, awesome.
