When trying to extract https://assetstore.unity.com/packages/3d/props/low-poly-ultimate-pack-54733 in Windows 10: .\unitypackage_util.exe LowPolyUltimatePack.unitypackage dump

Got:

thread 'main' panicked at 'called `Result::unwrap()` on an
`Err` value: Error("content: duplicate entry with key \"m_Name\"", line: 23157, column: 3)', src\commands.rs:46:58

Any way that I can help debugging further?

I used your previous release/build version of FBX2glTF for Windows --> in conjunction with the Unidot importer from (https://github.com/V-Sekai/unidot_importer) for my game project and it worked like gangbusters. Recently I had to re-install my project and use your newest version of FBX2glTF -- now I'm getting errors and can't open my project.

Not sure if it's possible, but do you ever make your older/previous builds available for download?

Any help would be most appreciated.

Looks like any new unitypackages no longer work with this tool

Needs bit rate detection

System: Macbook Pro i5 Ventura 13.3.1
Godot: 4.0.3
Unity: 2020.3.48f1

1. Generated unity package of polygonFantasyKingdom by rightclick on the directory in unity
2. Tried loading the ...unitypackage in godot
3. Got the following error (import folder with catalog.json and location.txt is created but nothing else btw.)

It appears that the official https://github.com/godotengine/FBX2glTF has received some fixes that haven't been pulled into https://github.com/barcoderdev/FBX2glTF yet

According to V-Sekai/unidot_importer#19 they have reviewed and are supportive of your modifications

Could you please submit your changes upstream as a PR or update barcoderdev/FBX2glTF from upstream?

unitypackage_util not found

After setting the variables (through UPackGDConfig), the utils are not asserting. The same issue comes from FBX2glTF if I comment the unitypackage_util line. Using Godot v4.1.1-stable.

Specifically an error in unpackgd_base.gd.

Does this asset support Godot 3.x?

I was discussing with the Godot community and they suggest that Godot 4.x is not yet mature enough. Especially for us since we need C# on mobile and Godot 4.x does not yet have that. We are currently porting Blocky Ball:

https://store.steampowered.com/app/1343040/Blocky_Ball/

And we've got ~3 months to port from Unity so every tool to help is a massive win! With that said, if it does support 3.x, just reply with a celebratory emoji and close this issue! :)

If not, how difficult will it be to get that support in there and how can I help (assuming it will be the fastest course of action for me)?

I know not many people use Unity on Linux but can we make OS specific parts just a bit more inclusive?

Packages that require another package need a way to be handled.

See POLYGON - Dungeons Map requiring POLYGON - Dungeons Pack

Possibly require them to be manually extracted to the same location first?

Discussion topics to be tracked once the discussion feature is open

Why this project combines with existing Godot Proposals needs a separate discussion?
When porting Unity features to Godot, we have a chance to combine the talents of Unity and Godot to evaluate how the Godot proposals could be BETTER implemented in Godot!

Great Job!
Great contribution to Godot Community!

Some models come in with incorrect scales. The values are off by 1/100, 1/10, 10, 100, etc.

An example package of this is the POLYGON - SciFi City pack: Billboards, Cables, Papers, and Skybox. Also see POLY - Medieval Camp.

Might be related to this in Fbx2Raw.cpp:

  FbxSystemUnit sceneSystemUnit = pScene->GetGlobalSettings().GetSystemUnit();
  if (sceneSystemUnit != FbxSystemUnit::cm) {
    FbxSystemUnit::cm.ConvertScene(pScene);
  }

  // this is always 0.01, but let's opt for clarity.
  scaleFactor = FbxSystemUnit::m.GetConversionFactorFrom(FbxSystemUnit::cm);

FbxSystemUnit::cm.ConvertScene(pScene) changes the scale and needs to be applied to the yaml import values?

The artifacts at https://github.com/barcoderdev/FBX2glTF/actions/runs/5040011556 have expired, didn't know this could happen, next time I'll be sure to not delete my copy.

When importing a unity package, each prefab that is made up of multiple meshes has Node3D nodes created to store the transform of the mesh.

However, when I convert, I also see the mesh itself has the same offset, resulting in this:

Additional Information

• I've tried converting multiple unitypackages, the picture comes from a Synty package.
• I'm using this build of FBX2glTF but also tried the official release from June 2023.
• v4.2.stable.mono.official [46dc27791]
• Windows 10

Please let me know if anyone has any ideas or needs more information. I searched quite extensively before posting here, so apologies if this is a resolved issue somewhere.

im using latest godot mono stable with LTS so it should work for at last this
im getting that project is too old and wont be omported properly anyone have any idea ? i supose gd scripts will be out of date too

Other than that, the textures, materials are imported correctly.

Hello,
I made two packages of two games made with Unity 2023.1 and I'm unable to open it with the latest revision.

I only get this message

The catalog.json file contains only the null keyword in it. Any clue?

• Create the placeholder nodes
• Figure out which attributes can be easily mapped
• Store all attributes somewhere on disk & reference it in node meta, for manual updates
