Unit measurements? (3ds max/maya)

[Plastik]

Does anybody know units setup for UDK in XSI? I cant understand scale measurement

Aside from LightWave I assume since it doesn't use "units", it uses feet, inches, etc. I assume modo is the same too since it's based on LightWave.

Usually 1 Unreal unit = 1 or 2 cm, depending on your scale choice. It can be more, but isn't recommended by Epic.

Of course, in (say) 3ds Max, you might have it setup for units, that's fine, you can define it for cm, or just work with units.

Thank you, that's good to know. Now I just need a way to get LW objects into UDK and I'll be golden! lol

12 inches = 16 UU seems to be the common factor for general mapping purposes, but I have also found that simply building the object in real scale (I use feet+decimal inches) and then upscaling 192% before exporting as .ASE seems to work admirably.

1 UU = .75 in. = 1.905 cm

Instead of thinking units you could make a BSP mesh in Unreal as a reference size object, export it as obj and use it in your scene.

I posted this in a reply in docs sections :

I like to be able to look at a model in max that I make as being measured in feet . The basic unreal character is 96 unreal units tall for a 6 foot model so 96/6 = 16 units per foot.
To get that in max so that I never have to scale objects on import here is what you need to do.

Inside Max BEFORE you create anything in the scene, this is very important nothing is in the scene.

Open Customize then Units Setup
Set the Display units scale to Fractional Feet and 1/1 in the drop down menu
Click System Units Setup
Change the System Units Scale to read: 1 unit = .8 inches
Click OK

Now 1 unit in max equals 16 units in the UDK, so 1 foot in max = 16 units in UDK.

If you want the grid to snap to it, then set it to :
Grid Spacing 1 foot
Major Grid lines every 10 spaces.


You can change the Display Units scale to something like Fractional Feet and 1/2 in the drop down,but be careful when changing this as it can result in objects that will import fine but have odd measurements like 15 x 16 instead of 16 x 16 because of rounding errors in max. Max is good for a lot of things, but precision isn't one of them. If you want precision you will have to use Autocad
