Modifying the variables of a Child Node of object scenes instantiated in the stage scene in the editor

[gertkeno]

You could add your own export to the root node that propagates down, or check “Editable Children” in the instantiated scene.

There’s a plugin “Hoist” I haven’t tried but aims to help, it requires Editable Children to be on though so I’m unsure how much benefit that is to you.

Hoist: Editing properties of children on the root node

Hoist allows you to select which properties of a nodes children/grandchildren should be editable from the scene root. Essentially an augmentation to Editable Children. There is a blog-post, which covers how it works.
