Assets that are imported using File < Import to Level, import at a different scale than when importing through the Content Browser
Screenshot attached to show difference in scale
Meshes were both set to 256 x 256 x 256 cm in 3Ds Max 2016
One pivot offcentered intentionally
Results: The assets imported using Import into Level are significantly smaller than the assets imported using Import to Game
Expected: Assets imported using either of the methods mentioned above will be the same scale when imported
