I can not reproduce this on Godot v4.2.1 with the steps you provided. I tried both a Node3D root, and a MeshInstance3D root node for the first scene. In both cases, I used a BoxMesh with StandardMaterial3D.

Either way, there's a fix for local_to_scene coming in 4.3 (#71578) which will likely fix this issue as well. Just not sure why I don't get the error myself... Can you try reproducing it again on a 4.3 dev build?

ok,tried the same in 4.3 dev3.
To those errors that were, one warning has been added :

drag n drop scene node_3d.tscn to node.tscn cause error, even if you didnt place it, just hold

Can confirm now, it only happens when doing drag&drop into the 3d view - it does not error when you drag into the scene tree. It also doesn't error when disabling resource_local_to_scene

yeah, exactly, also doesn't error when add_child()

The warning is another issue, see #88125.
