Short description of error

When I am exporting the animations using the fbx exporter something strange is happening with scaling. When they are imported to unreal then it gets scaled-down to very small. This does not happen in the 2.83 version. In viewport it will look correctly but problem starts showing up animation editor is opened in the unreal.

Exact steps for others to reproduce the error

• • Export the animation as fbx file
• Import it to unreal engine
• Open the animation and play

Based on the default startup or an attached .blend file (as simple as possible).
