How to make stock parts invisible?

[Farstar]

I know this usually gets asked the other way around but I want to attach two rockets to each other and make them look like two individual rockets. Therefore, I want to make Modular Girder Segment XL invisible and use it to attach the two spacecrafts. How can I make it look transparent in the game?

Should I delete its texture in KSP folder or should I change its config? Thanks in advance.

I think you should modify the texture

Like in Blender? What should I do?

Editor Extensions Redux (currently not 1.1.3 compatible but I'm sure it will be soon) allows you to do large offsets between parts. You could achieve the effect you want without the girder adding weight and drag, just by slapping the fuselages together then separating them

Yes, this.

If it was me, I would also use the Offset gizmo.

Instead of trying to change or create new parts.

Editor Extensions allows for near unlimited offset.

Yes, thank you! This is exactly what I wanted.
