Hello everyone, I have heard something that if I want to model something in 3ds max I need to change the scale unit to 16 Unit per foot.The question is how I am going to change it?Anyone can help with the detail explaination?

Units per foot? That sounds odd... where did you hear that?

Anyway, I'll assume you don't need to change any scales, just as long as you model the model in the right sizes... that scaling is probably just for easier reference.

Well, if you have a person who you want to be 6 feet tall, you make sure he is 6 * 16 = 96 units high in 3ds max. By default, UnrealED and 3ds max use the same unit scale.
