[Unity] Import skeletondata.asset files error in Unity Editor for OSX

[tuzihao]

Unity(Latest version 5.6.0f3 - iOS platform) would freeze when import SkeletonData.asset file generated by spine

Are you saying the Unity Editor freezes? Or it freezes when testing on the device?

Were there any errors logged?

[tuzihao]

Unity freezes when I open project. There is Unity crashlog in the /Library/CrashedAssetImports.txt. It freezes when import skeletondata.asset. But import this data after project opened, it would succeed.

[pharan]

So Unity editor freezes.
Are you using Unity for macOS/OS X?
We have not seen this problem yet but thanks for reporting. We still need to investigate the cause on a test machine.

[tuzihao]

Yes MacOS Sierra Unity 5.6.0

I met same issue here, with Mac Unity, 5.6.1f1, editor freezes when "importing small assets". after open log, it stops at importing SkeletonData.asset

Edit: It turns out after disabling "Metal API in Editor" will fix the problem.

Thanks for sharing, @ownself!

That doesn't quite make sense, but we'll try to see what's up.

I wasn't able to reproduce this crash.
Unity 5.6.1 in OSX, I had Metal enabled and tried to import a raw set of json, atlas.txt and png. I separately tested importing a set with SkeletonDataAsset and AtlasAsset. No crashes.
So this might may not be happening to all setups.

In any case, disabling "Metal API in Editor" seems to have helped people who have run into this problem.

Having the same issue when I checkout my project on a Mac. According to this issue (link) it would start after deleting your Library Folder. In my case, the workstation never had a Library folder to begin with, so it was never populated beforehand, therefore the issue might be related in this fashion...

We are experiencing this problem on macOS 10.12.6 with Unity 5.6.3p1. Can someone explain how to disable the "Metal API in Editor" please?

*Update: for anyone curious the answer is to change {project root folder}/ProjectSettings/ProjectSettings.asset
from:
metalEditorSupport: 1
to:
metalEditorSupport: 0

You could have also accessed it in one of the preferences menu inspectors. I forget which one, I'm currently not on a mac.

Unfortunately, using the editor was not an option as the project could not be opened using the metal API without significant changes to the Assets/ data. A 1 character change in a single text file seemed the less invasive workaround.

try this.

spine-unity/Asset Types/Editor/SkeletonDataAssetInspector.cs

#if UNITY_EDITOR_WIN
[CustomEditor(typeof(SkeletonDataAsset)), CanEditMultipleObjects]
#endif
public class SkeletonDataAssetInspector : UnityEditor.Editor

If someone is still having this issue in the latest versions of Unity, please post a comment.
