Steps for reproduction:
- Create a new project
- Add a few placeholder meshes to the default level, save everything
- Go to file → export all
- Import the FBX in Maya
- (in Maya) Create a new camera, animate and export it as an FBX
- Back in UE4, create a matinee
- (In matinee) go to file → import, import the camera FBX
- You should see the camera animation is all wrong (flipped axis etc.)
