The new scaling within the Unreal Engine 4 is that 1 Maya Unit is equivalent to 1 centimeter in the real world. Due to this change in scaling we will need to make some adjustments to our grid. The good thing is that due to this change in scaling the grid settings are very easy to figure out.

There are 30.48 centimeters in 1 foot. What we can do is set our subdivisions to 16 and then multiply the number we want our grid snapping to by that subdivision setting. For instance, since we want our grid to snap every 30.48 centimeters all we have to do is multiply 30.48 by 16. The result would be 487.68 which we would place in the “Length and width” as well as the “Grid lines every” options. This would make our grid set so that at each grid line would be separated by 30.48 Maya Units or 1 Foot.

While setting our grid to represent 1 square foot is a good thing for quickly setting the height of an organic model or prop, it is not good for developing objects that need to use the Snap To Grid inside of the Unreal Engine. The Unreal Engine’s Snap to Grid options only allow the object to snap at a complete integer. So any point numbers will not snap correctly. For instance you can snap to the number 1 but you cannot snap to the number 1.48. As a result you will want to adjust your grid when developing scene building models such as walls. Again, if I wanted to make the grid setup so that each line was only 10 Maya Units apart, which is a whole number; all I would have to do is multiply 10 by 16 and add the result to the “Length and width” as well as the “Grid lines every” grid options.
