Hi Armin, I’ve done a few more tests with 2.8 and have had some seen an elusive bug in the FBX exporter but for the most part it seems to behave the same as the 2.79 export. Rotation seems to be fine when opening the file in other 3d viewers (Sketchfab, Windows MR, etc…) but I still find the rotation in Unity to be weird like before. The Apply Transform hasn’t gotten any further love as far as I know. Are you using a rig? For whatever reason, applying an animation in Unity makes it behave a bit better than just the mesh by itself.
