How to fix Flickering Skeletal Mesh in Unreal Engine 4

Importing a Skeletal Mesh into UE4 is simple, just a matter of a .fbx drag and drop, but in some cases this simple operation leads to a very annoying problem: mesh flickering in viewport.

It turns out that adding the Skeletal Mesh to a Skeletal Mesh Component inside a Blueprint and checking the "Component Use Fixed Skel Bounds" options fixes the problem!

In some cases checking also "Use Bounds from Master Pose" does help too.
