3 DMAX unit management & udk import Conversion

3 DMAX unit management & udk import conversion 1) display unit settings determine how many attribute panels display the length and width of objects. As follows:
 
The height of the old white is 176 cm. If the cube is used for modeling, the parameter panel is shown as follows:

2) The system unit setting of 3dmax determines the actual height of the modeling object. As follows:
 
The old white height is 176/2. 54 = 69.29 inch. The number 69.29 is stored in the model file. When someone else imports an old-white model file, 3dmax reads the number and sets the conversion according to the system unit of others.

3) When you export 3dmax to fbx, you can set a unit conversion.

If it is automatically checked, the current system unit is used. In this way, the height of the old white model is still 69.29 in the fbx file.
If you deselect the check box and convert the value to centimeter, the height of the old white model is 176 in the fbx file.

4) by default, udk uses the number in fbx directly as the model unit without conversion and rounding.

If it is automatically checked, press "Inch", as shown in 69.

If the tick is removed, the value is 176 in centimeters. Of course, 176 of the old white in udk is much taller than 69.

5) The measurement conversion of one unit in a udk corresponding to the real world is explained as follows in the official document:

In all of the unreal
Tournament games, 1 unreal unit is equal to 2 cm.

In Gears
Of War approximately 2 unreal units equal 1 inch, because the characters are 156 units tall and a floor of a building is 256 units tall. this was decided on for grid purposes and so our cover height worked out well.

Most licensees use a scale of 1 unreal unit to 1 cm.

So the old white height, whether it is 176 or 69, as long as other models are converted according to the same measurement, the remaining problem is to adjust the camera zoom to adapt to the feeling of players. If Unreal Tournament is used as the game base (gametype = utgame/udkgame), camera scaling is not adjusted, and some ut mesh files are also used directly to get the same size, then 3dmax should set the system unit 1 = 2 cm. In this way, the height of the old white is 176/2 = 88 in the udk. If sk_crowd_robot and la are put together, la is solid.
