"The path to the Blender executable" is unclear

[andreymal]

"Importing .blend files directly within Godot" says:

configure the path to the Blender executable in the Editor Settings (Filesystem > Import > Blender > Blender 3 Path).

"the path to the Blender executable" means that I should set /usr/bin/blender. However, when I set it, Godot 4.0.2 prints a warning:

modules/gltf/register_types.cpp:72 - Blend file import is enabled, but the Blender path doesn't point to an accessible directory. Blend files will not be imported.

"directory"??? The documentation doesn't say anything about directories!

But okay, when I set /usr/bin, importing .blend files works.

I think the documentation should say something like:

configure the path to the directory containing the Blender executable in the Editor Settings (Filesystem > Import > Blender > Blender 3 Path).

(By the way [1], I don't understand why Godot requires a directory instead of an executable file, but that's probably a topic for another issue)

(By the way [2], autodetecting doesn't work for some reason, but that's probably a topic for yet another issue)

This also occurs on the current source-compiled build of Godot. I get this outputted as part of the console (KDE Konsole) output.

This is the part that does automatic detection: https://github.com/godotengine/godot/blob/f8dbed4d0aef09ae7f4e3d66213268dba23a31d6/modules/gltf/editor/editor_scene_importer_blend.cpp#L270-L276

It only works if blender is in the system PATH, and it does not work if either Godot or Blender are installed using a Flatpak.

Since godotengine/godot#85448 is merged, this change should be reverted now 🙃

As of v4.2.2.stable.arch_linux this is still the case, /usr/bin/blender errors but /usr/bin/ works.
