A quick tip - How you can make an interstage fairing

[samamstar]

It's an open secret at this point that KSP2 is having a rocky launch to say the least. One problem that many of you have likely noticed is the lack of inter-stage fairing support, at least not as strong as in KSP1. But fret not! I have found a way to accomplish this that is (mostly) free from jank and wobbling nodes

The secret lies in 1 part: the engine mount. This humble beast, despite his total lack of configuration options or multi-engine connections (srsly, what!?), still lets us attach parts in a manner that resembles the inter-stage fairings of yore

A simple example. Note the decoupler below

A slightly more interesting example. Note that the interstage *widens* to the medium fuel tank! Cool!

Nice guide!

Engine mounts can also be used to accomplish the job of supplying interstage nodes within an ordinary fairing, too. It works much like you’ve described here, except you need to flip the engine mounts over so that their interstage node is above them, not below. As with your design, you’ll need some decouplers (tiny ones will do), and possibly some Clamp-o-torn jr’s to help deploy your payloads.

The major downside to engine mounts is they’re 700kg each, no matter what size you need, but at least they can stand in and get the job done!

Engine plates work for multiple engines.  Simply look up that the engine plate, select the symmetry for the number of engines you want to mount, then attach the engines (while looking up to avoid auto-snap).  This does not work on just a fuel tank, so it seems this is the way engine plates work in KSP 2.

Following these instructions but still running into a bug that keeps the stages attached. Thoughts?

I posted a response to the same thread you linked to.  I think this should work for you.
