Both .blend and .fbx imported meshes correctly. Materials were of course missing, but they’ll be replaced by textures / can be recreated in Unity. Blens import used to be glitchy a while ago and I remember there were some .fbx issues as well (propriatery reasons I believe). So it depends. Other formats. Same. Just try and see. If it’s not working, go around with .obj or other “universal” format.
