Can stack separators create a fairing that matches diameter of the separator on engines?

[tater]

Say I have a 1.25m LV-T30 stuck to a 2.5m tank on my CSM. It would be awesome to put the 2.5m stack separator on there and have it make a 2.5m fairing, instead of a 1.25m one (which means I have to then also make an interstage, adding a bunch of parts to the rocket for something I am throwing away, anyway).

How many time did I wondered myself...

I think the subtlety is that the separators would have to also check the diameter of the "node" before the engine (and overide the previous size), the engine obviously already contain the data saying that it is a 1.25m or a 2.5m part, but I doubt every other fuel tank do.

Only work-around I know (since 1.0) is to add a fairing hiding the decoupler.

Technically, the decoupler doesn't create the shroud, it's created by the engine itself. Stack anything directly below an engine, attached node to node, and the shroud appears. While it would be nice to have something like this, I think the answer is likely to be that it's too complex to reliably figure out what should happen. The situation right now is at least 100% predictable and reliable â€â€.you'll always get a shroud which matches the size of the engine.

I know there are other cases where it might not be so simple, but in the OP's example the solution is just to use a Poodle, not a LV-T30, for roughly the same thrust and the correct size for the stack.

The poodle is so awful looking I almost never use it, honestly.

I think stack separators should also be fairing bases. The fairings themselves cost weight and funds to build anyhow. An engine should be able to remove its own autofairing interstage when building a fairing from an attached stack seperator.

Also:

Squad please make stock fairings act like a strut to whatever component you are closing an interstage fairing around. PLEASE!

100% agreed. I tried to do an Apollo mission yesterday, with a LEM extraction... the interstage fairings add no structural stability, so the whole thing started wobbling around... :/

Also, doing a LEM extraction revealed itself being very difficult with the stock interstage fairings. You are forced to use a decoupler between CM/LEM, wich will stay in the way when you want to turn around and dock...

The ideal would be to have only the interstage fairing to hold the two (firmly ) , so that ghere would be nothing between LM and LEM inside the rocket.

Anyone knows a workaround ?

I thought it would be more of a gameplay question, but I would actually like this. Adding fairning building ability to the decouplers shouldn't be complicated

Take a look at this tutorial, it may be useful for your situation.

PF does it better.

The simple solution would be to make engines check the size of the part below them instead of their own size when they create the fairing. It could then count some parts as not having a definitive size (odd-shaped parts, Mk. 2 sections, etc.) and in those cases use its own size instead.
