Import Errors

[mrlinds]

When upgrading unity, or opening the project for the first time, tiltbrush models always fail to import properly. After initial import has completed, we then need to reimport all the tiltbrush assets again.
I assume it's an order of import with the models importing before the brush definitions are available.

Yeah; editor extensions are really supposed to be distributed as dlls. On initial import, the C#, the models, the ScriptableObjects, etc are all getting imported at the same time and Unity doesn't know anything about dependencies. IIRC there are also restrictions on when you can import new assets.

In this case, I am not sure that compiling into a .dll would fix it since it's a dependency from the C# code to a ScriptableObject. It's quite irritating, I agree; and I haven't thought of a reasonable fix.

Hi, I am running into this issue. Any ideas for work arounds / fixes?

Edit: After better understanding above messages I realize re-importing tiltbrush assets is an ok workaround. If anyone else finds this thread:

• to make your life easier, in your Unity project keep all of your .glb / tiltbrush files in folders dedicated to tiltbrush files.
• For this example steps to fix, I assume all of your .glb files are stored in Assets/3dModels/TiltBrush
• Steps to fix:
• Copy the contents of Assets/3dModels/TiltBrush to somewhere on your PC outside of your Unity project
• In Unity, delete the contents of Assets/3dModels/TiltBrush
• Drag and drop the contents from Windows File Explorer back into Assets/3dModels/TiltBrush
• You should not see any .meta files changes and your local install of the unity project should not have this issue anymore.
