No scene JSON file when exporting from Unity, Can't import in Unreal. #58

Open BrayanMinkov opened 2 years ago

BrayanMinkov commented 2 years ago

Hey,

I've been trying to migrate a scene from Unity to Unreal. I am using the recommended versions for both engines and following along with the tutorial videos you posted. When exporting from Unity I only get a folder with JSON files of the meshes and no scene JSON file like in the video. I do have a scene file inside the folder with the meshes, but upon attempting to import the scene JSON file into Unreal - Nothing happens. All I can see is that I get an error that states :

"JsonLog: Warning Prefab import is currently disabled"

Please let me know if there is any possible fixes. Thanks in advance

@BrayanMinkov Hi. I need to know more information. Unity version, unreal version, your operating system. If you can share test data, that would be even better, as I'd be able to take a look at it.

I have the same issue, unity version is 2018.3.0f2... I don't think the UE4 version matters as the problem is with the exporter(Unity), but UE version is UE4.26.2 or UE4.24.3... The JSON, doesn't appear... only the folder with json files in it... Please help, I'll be active until issue resolved.

When I click "Begin Export" in Unity, it exports the Folder only, however when I go to windows "Quick Access" Panel I see the json file with the same name, but when I open it... It says "Theses files could not be found and will not be loaded"... then I click "Open File location" on the json and it goes to the folder with json files, but no json there... So maybe it's being created but removed/deleted after... please help

Forgot I opened this problem, sorry about that.

So what I managed to figure out is that having game objects with scripts or other code/logic attached to them can mess up the export and give you an empty folder. After I removed all those I got a good export but couldn't get it imported into Unreal 5 (don't remember the exact reason for that).

What I ended up using is Unity's option to export a scene as an FBX (I believe it's in the "file" tab). Which I later imported into Unreal 5. It's a pretty messy alternative, but it works for migrating meshes.

Hopefully, that helps.

Thanks for reaching back to me! I was too deep into the project and completely missed this. I managed to find an alternative, I posted a comment on it.

Thanks again <3
