Hey guys, I've been playing a while with Proceedural Fairings, but I've honestly only just started to try to use interstage fairings. With proceedural parts, it is often more efficient to have a rockeet with a diameter that isn't 1.25 or 2.5, and with the 'Thrust Plate', I've been using a lot of engine clusters too.
But I can't exactly figure out the interstage fairing. I've gotten it to the point where I can make it look good, but it still claims it's shielding 0 parts. Also, I don't understand what the decoupling stage is for, since it doesn't seem to be a regular stack decoupler.
I'm trying to make more realistic looking rockets that still perform well. Interstage rings/fairings are a very common part of real rockets, but KSP (even with mods) seems to not consider them very important.
