Hi Adam,
I realy thanksful for your this "3DS MAX + UNREAL ENGINE 4: EASY REAL TIME FOR ARCH VIZ" tutorial, I very Curious about to learn Unreal Engine so You fulfill my wish by this tutorial :) .
I have always confused about in 3ds max units setup so please tell me what the units setup kept for max file in this tutorial
I use feet and inches in 3ds Max, but units in UE4 are centimeters. You can also do conversions and scale if you need to. In newer versions, UE4 figures out the conversion for me and everything is at the right size.
