    Hello all,
    With blender 2.8 beta
    Create a new project (File > new > general)

    Select the default grey cube on the scene and export it in fbx (File > export > FBX(.fbx))
    Export FBX > Selected Objects

    save it in directory "Assets" of a new unity project
    In unity 3D, the cube is well exported but the rendering mode in unity 3D of the material shader is Transparent !!!

    Return in blender 3D and change the Base Color of the material that is white grey (R:0.8 G:0.8 B:0.8 A:1) to yellow (R:1 G:1 B:0.0 A:1)
    repeat export and replace the new file in directory "Assets".

    In unity 3D, the new cube is well exported but the rendering mode of the material shader is now "Opaque".

    It is not a problem of geometry but a problem of color.
    Have you a solution ??
    Thanks a lot

    I'm experiencing the same issue. Additionally, I can import into Unity if I export to FBS from within Blender, but if I attempt to load the newer (Blender Version 2.8 Beta) .blend file, Unity gives me the following error: "Blender could not convert the .blend file to FBX file.

    (note: I know that 2.8 is currently in beta and thus unsupported, but since the purpose of releasing beta version is for generating bug reports like this one, I thought it'd be useful to document the issue)

    Same problem here, I think it's a bug in the Blender 2.8 FBX exporter. If you set the material's color in Blender to pure white (1,1,1,1) and then export to FBX, the material in Unity becomes opaque as the alpha is read correctly as 1.
    A task for this bug has been opened.

    For now, override (remap) the material in Unity with your own as a workaround or go back to using Blender 2.79 until the bug gets fixed.
