@Gummy, I had the same issue and I managed to export using the Convert as Wavefront OBJ format. You must select all the mesh files and the fbx file of type GameObject of the same name as well.

@Rhod Briar I do believe you're onto something, and I'm not sure what's causing it- Textures and other stuff seem to be exporting properly... But I can't seem to get models to export right- I've checked multiple sources and they are being exported with the fbx filename but the data seems to be corrupt or something?
I really don't understand it

@Gumball can try to compar3 dile metadata to see if your wxport changes anything?

So, I finally have had time to set aside and try ripping models from the game using Hades, but I'm having this issue with Blender where I can't import the models, Binary or ASCII. I keep getting an "invalid header" error.

@gumball Jon
Yes it is rippable. Almost every model can be ripped with Hades Workshop (the world map is a bit more complicated but that's about the only exception).
However, I don't have that model exported and I cannot do things like that myself at the moment.

Hey, this is a long shot but models-resource.. com is actually garbo and I've been hunting for days-
Is the Friendly Yan in the models that are rippable/ do you have a copy of of the model?

Thanks a bunch i will try that and let you know!

You can try:

- In Hades Workshop, open "Tools -> Unity Assets Viewer", then "File -> Open -> FF9_Launcher.exe", then "Archives -> p0data4" and then you'll have almost all the 3D model assets listed.
- If you select one, right-click and "Export selection" will generate the FBX in your game's folder (somewhere in a sub-folder of "FINAL FANTASY IX/HadesWorkshopAssets"). You can also try to export the model into another format but it doesn't work well: better export these models into either FBX Binary or FBX ASCII. That's for the export part.

- I think that Blender can import well the FBX ASCII files generated by Hades Workshop this way. Last time I checked, it couldn't import the FBX Binary because the format version was not supported. Maybe it was the other way around though.
- On the same line, I'm not sure if Blender is able to export a modified model into the FBX format. Hopefully it does. AutoCAD, on top of supporting terrible antisocial land destructions, is bad at sharing the FBX format specifications. Let's say for the sake of the argument that you managed to get a properly modified 3D model in FBX. Replace the FBX originally exported by the Unity Assets Viewer by that one.

- Back to the Unity Assets Viewer, right-click on the model you exported and use "Import selection": it will pick the file exported and updated in the folder where it was previously exported. Hopefully, it will (1) show a success message and (2) work properly in-game. It could be that it gives a success message but it bugs in-game.

You should better try the last step with the following options in "Automatically Convert 3D Models": "Only update existing nodes" + "Import meshes/materials" but without "Import animations". I think those are the safest.
It's still a very buggy feature, so I don't guarantee any success, unfortunatly.

Last time I've checked, it worked to export/reimport the model without modifying it. But it was very complicated to reimport it after any modification (because 3D tools tend to change the model formats).
