Unit snapping in Unreal Engine 4

If you open a blank map in Unreal Engine 4 or the different viewports in the editor, you will notice a grid. This grid can change dynamically depending on the current unit snapping measurement applied in the editor. The spacing between each grid square will determine the number of units an object will move when you place or transform objects in the editor. Back in Unreal Engine 3 or the UDK, the grid snapping would follow the power of 2 (2/4/8/16/32/64/128/256/512/1024/2048), but in Unreal Engine 4, the grid snapping follows these values (1/5/10/50/100/500/1000/5000/10000). The main reason for this change is due to the fact that Unreal Engine 4 uses the value of an Unreal Unit equaling 1 cm instead of 1 uu equaling ...
