Blender 3.0 Failure

Not sure if you guys are supporting Blender 3.0.0, but having installed from the Windows Store, Blender auto-updated on me and now I have 3.0.0 installed.

In any event, a scene that I was previously able to export is suddenly throwing an error:

The relevant bits are:

```
AttributeError: 'RenderSettings" object has no attribute 'tile_x'
```

This really feels like a change between 2.9.x and 3.0.0 in Blender, but please let me know if there's something that I'm likely to need to change in my scene to fix this.

Start by reproducing the export failure in Blender 3.0 and compare the RenderSettings API with Blender 2.9.x, focusing on the missing tile_x attribute. The issue names no files or tests; done means the previously exportable scene completes successfully without this AttributeError.
