Godot 3.1
If I export my model in gltf, glb or dae inside Godot and add it in the viewport, it will instance it as a scene and the model will be displayed correctly. But if I edit the model in Blender and overwrite the file, the model won't be refreshed until I open it as new inherited scene.
If I keep the tab open the model is always updated when I overwrite the file.
For example if I export Suzanne in .gltf in Godot the model is displayed:

Then if I edit the model in Blender and export it, the texture are updated and loaded but not the model and UVs, I get that:

I need to open the model in an inherited scene to update it. I keep a tab open to update the model or to close Godot and relaunch it to update everything.

Is a duplicate of issue https://github.com/godotengine/godot/issues/25243
I'm reporting this so far unsuccessfully since January :-/
And additionally the .escn exported models (from the godot blender exporter
https://github.com/godotengine/godot-blender-exporter/tree/blender2.8)
do not update until you delete the .import folder and restart Godot …
Could you also try to confirm that? Thanks.
Close as a duplicate of https://github.com/godotengine/godot/issues/27409. Keeping the older issue.
@fire you linked the same issue number, couldn't follow it :b
Sorry this is the older issue. Reopening.
I'm also having the same issue. Exporting and overwriting a gltf from Blender does not yield an update in the Godot editor after the re-import happens.
