View Full Version : UNITS in runtime

Hello everybody, I have a simple question, what is the correspondance between unreal units and real units in cm or in inch.
For architectural projets, it will be really helpfull.

Thanks for your answers.

On wiki, you can find these approximations:
UU=Unreal unit

256 UU = 487.68 cm = 16 feet.
1 meter = 52.5 UU
1 foot = 16 UU
1 cm = 0.525 UU
1 UU = 0.75 inches

In max, if you make a 6.52x6.52x6.52 meters of a box, it will match exactly 256x256x256 of a basic unreal room.

However, it's not suggested to go crazy about precise dimensions. For instance, according to upper list, if you want to make a 2 meter room don't subtract a room of 105x105x105 as BSP needs powers of two. Even I'd not subtract a room of 106x106x106. I'd do 128x128x128, since it's much better for bsp. So in general, subtract room sizes by powers of 2 and then "add" static meshes to lower the dimensions on ceiling or floors. You will have less headache.

Actually, there is no real UU to real life conversion. The info on the wiki is just the values Epic used in most of their games.
