I recently reformatted my hard drive and lost all my bookmarks. But I remember a forum thread on UDK's website that had a general guideline I followed that told how tall and wide certain objects should be in unreal. (Windows should generally be X units above the ground and X units wide. Doors should be X units wide and x units tall etc.) I can't seem to find it again. Does anyone know what I'm referring to, if not does anyone have something similar?

A quick google search finds this:

That what your looking for?

YESS!!! THANK YOU!!! lol i searched an hour and couldn't find it lolol

I found that 1UU = 1 3DS Unit = 1,8cm

For example, standar guy (IronGuard) in UDK at 1UU=2cm is 1,96m tall, using 1UU=1,8cm is 1,76m tall (for me 1UU=1,8cm looks more real).

Keep in mind that Epic likes to make their characters all slightly larger than the average person, so you might not want to use IronGuard as a realistic example.

wooooooah no, people gotta stop quoting the UDK docs they are really outdated.

The defualt setting for UDK now is 1:1 with max, so 1 udk unit = 1 max unit = 1cm

Now the old scale that gsokol posted is still correct but you have to switch to DeathMatch in the world properties > default game type.
