To reproduce:
1. Open users attached project "TextureMipStreamingRepro.zip"
2. Open "LoaderScene.unity" scene and enter Play mode
3. Observe as the loaded models have a very different level of details, the green object is exported from Maja using meter scale
4. Exit Play mode and open "ContentScene.unity" scene
5. Enter Play mode
6. Observe as both models have the same level of detail

Expected result: both objects have the same level of detail after the scene is loaded
Actual result: object that was exported from Maja using meter scale is really pixelated

Reproduces on:
2018.2.0a3 2018.2.0b1 2018.2.0f2 2018.3.0a5

Does not reproduce on:
2017.1.4p2 2017.4.7f1 2018.1.9f1 2018.2.0a2

Notes:
Tile_CM.fbx is exported from Maja using centimeters scale
Tile_M.fbx is exported from Maja using meters scale

When the scene is loaded from LoaderScene.unity scene observe in the Project window - albedo, normal maps, occlusion maps. The ones that are assigned to Meter exported .fbx file get pixelated.

Also: If you select
Project window > Tile_CM > Tile you can see that Mesh Metrics[0] - 7.109027
Project window > Tile_M > Tile you can see that Mesh Metrics[0] - 71997.6
