Upd. I use the blender and so I thought that he was to blame.I make a new model and tried to export the different versions of Blender (2.69 2.73 2.75 2.76) In a blender constantly changing scale, used the UE4 Tools. Nothing helped. If you change the scale when importing, the mesh changes the scale and the collision remains the same. Bug? or I do not understand anything.
Sorry for my bad English.
