Can geometry nodes output a vertex group other/next modifier could see and use?

[Okidoki]

If i hadn’t read your other thread:

Vertex normals transfer in geo nodes?

Is it possible? Like what data transfer modifier does? What is vertex normal reader in GN for the start?

i properly would not even in the slightst know what you might thinging of… but TBH i don’t understand this anyway…

Especially:

@Ivagr

The way they would be exportable in fbx.

You may have to elaborate this to get a more suited answer.
