Can't import specific .blend file.

I have been using blender to create and import 3d models for a long time now. But today when i tried to import .blend file it keeps getting stuck at importing. I use Unity 2019.4.20f1 and Blender 2.91.2

It is a file of 266 mb and after 30 minutes of waiting without any progress I shut Unity down and looked at the files in the explorer. And the .meta file is always 1 kb. I have tried to export it as a .fbx and .obj but nothing works. I even tried importing it in a new project and that doesn’t work either.

Are there any requirements for a .blend file that I don’t know about?

Help would be really appreciated. (Sorry for my bad english)

Edit: Updated Unity to 2020.3.20f1 and Blender to 2.93.5 and it still freezes while importing my .blend file

Importing a blender file will just convert it to fbx behind the scene.
I would try to export a fbx directly from blender and then importing that into unity.

Did you ever sort this out? I just ran into the same issue. In my case it’s a duplicate of a .blend that is already in the scene.

My solution was setting compression to very high in the import settings because the model had far too much polygons. That fixed it and made my game run really smooth

Hey BCC_,

Sorry that we missed this. If you still have the file, does Blender export it to FBX OK?

If so, then could you look at filing a bug with the .blend file attached?

We’d be happy to look into it for you.
