Imported object exempted from lumen.

Hi all,

I am obviously doing something wrong, but for the love of the mystic guy with a big staff I cant figure out what. I have exported mesh with texture and normal information with triangulated faces from blender into FBX. And then imported it into content browser (both including and excluding nanite option). The rendering of the object is fairly said… broken. However, I noticed that the object does not appear in the Lumen visualizations. Why would it be excluded, and how would one make it included into lumen rendering?

I have just checked, and it also does not have lumen cards generated.
