Model is missing when Blender file is imported into Unity with Duplication method set to Group in Blender

Asset - Importers

-

How to reproduce:
1. Open the "SampleScene" Scene in the attached "case_1156259.zip" Unity project
2. Drag and drop the "cube-group" and "cube-nongroup" Assets from the Project tab into the Scene
3. Observe the GameObjects in the Scene view

Expected result: both GameObjects are visible
Actual result: the "cube-group" GameObject is invisible because its model is not imported

Reproducible with: 2018.4.1f1, 2019.1.5f1, 2019.2.0b4, 2019.3.0a4

Note: in Blender, Groups cannot be assigned to the Group Duplication method due to an issue with Blender only allowing the selection of deleted Groups. Manually exporting the Blender file as FBX seems to successfully import the model data to Unity. Reproducible on Unity versions 2018.3.13f1 and newer, 2019.1.0f1 and newer, 2019.2.0a11 and newer, and the entire 2019.3 stream due to Unity being able to convert files in the specified versions only. Not reproducible with models made on Blender 2.80, as the Group Duplication method is unavailable.

  1. Resolution Note:

    This is actually an exporter issue, Blender ( before 2.80 ) has two different FBX exporters ( binary and ASCII ). The ASCII one does not export meshes with group Duplication set to group. When importing .blend files in Unity, the file is converted to FBX under the hood using the ASCII exporter, so basically you'll get the same result by manually exporting the FBX from blender with the ASCII exporter.
