FBX import using FBX2glTF not working

[stryker313]

Godot version

4.0 Alpha 6

System information

Windows 10 Nvidia GTX 1060 Intel i5 4690k

Issue description

FBX animations that I attempt to import do not import.
I have set the fbx2gltf path, and still nothing. The file will be in the editor, but it has a red x through it.
For reference, I put the fbx2gltf.exe that I used in the minimal repo project

modules/gltf/editor/editor_scene_importer_fbx.cpp:83 - FBX conversion to glTF failed with error: 105.
  editor/editor_file_system.cpp:1928 - Error importing 'res://smallMesh@Praying (1).fbx'.

This happens with animations of all FBX type, regardless of origin.

Steps to reproduce

1. Set you fbx2gltf filepath to the FBX2glTF.exe
2. Move an fbx file into your project directory using your file manager (not dragging directly into the editor)
3. The fbx file will not import (fbx file has a red x through it)

It's choking on the parentheses in the file name:

sh: -c: line 1: syntax error near unexpected token `('
sh: -c: line 1: `"/home/akien/Projects/godot/toolchains/FBX2glTF" "--pbr-metallic-roughness" "--input" ""/home/akien/tmp/godot/bug/FBXimportbug/smallMesh@Praying (1).fbx"" "--output" ""/home/akien/tmp/godot/bug/FBXimportbug/.godot/imported/smallMesh@Praying (1)-ffb1f0ad0b110cb34540e145f57fa585.glb"" "--binary" 2>&1'

Might be missing escaping / I might have removed the ones @fire put by mistake when reworking both FBX and Blender importers.

I renamed the file to "anim" and it still doesn't import.

[akien-mga]

It imports OK for me when renamed to anim.fbx:

Just to confirm, it IS the fbx2gltf.EXE from [V-Sekai fork] for windows 10 that I am suppose to be using? I don't really understand what the issue could be...

Yeah, I just tested with the latest version from https://github.com/V-Sekai/FBX2glTF/releases/tag/v0.12.9-p2 and it works fine for me on Linux.

It's worth noting that the V-Sekai readme mentions that on Windows it requires MSVC redistributable, maybe that's missing on your end? https://github.com/V-Sekai/FBX2glTF#platform-binaries

Can you try to run FBX2glTF.exe manually from the command line? With e.g. this command:

FBX2glTF.exe --pbr-metallic-roughness --input anim.fbx --output anim.glb --binary

I can reproduce the bug. I don't know why yet.

g .fbx fails to import. Also x y.fbx too.

Expected "broken" result.

#57895 can be resolved by disabling lods. @SaracenOne Also mentioned a way to apply scale to the mesh. @reduz mentioned applying the rest.

Will report back on the MSVC in a bit.

Will report back on the MSVC in a bit.

Your test above shows that running FBX2glTF.exe worked and generated a .glb. So it seems to work fine, you seem to have the required components.

It's weird if it still doesn't work in the Godot editor though, as it runs the same command.

Looks good akien-mga@d4b54e3 if it works on the test case with fbx2gltf on Windows.

[akien-mga]

@stryker313 Once the Windows CI builds finished for #59998, you should be able to find a Windows editor binary to download here: https://github.com/godotengine/godot/actions/runs/2111701311

Could you try it and confirm if it fixes the FBX import issue with a name that contains (? It might be that this bug was actually Unix specific though, and if so the bug you're experiencing even with anim.fbx might be different.

[stryker313]

@akien-mga yeah it works now 🍡

[akien-mga]

Great, so the double quoting was also a problem on Windows (would end up as "FBX2glTF.exe" "--input" ""anim.fbx"" ... which likely doesn't work on Windows).
