Map scales

Since I'm new to the whole map making side of Halo, I have a quick question about scales, since the last thing I want to do it make my map and find I've made it completely the wrong size.

I was wondering what world units are? Since MC runs at 2.25 'world units' a second, I was wondering how I can change these units into generic 3DS Max units so I can more accurately scale my maps (I've worked out how many world units some of the current maps must be, but that's not much use without knowing how many 3DS Max unitis a world unit is).

Secondly, are the .gbxmodel files scaled to ingame size, or should I not use those as a basis for scaling objects in my map?

Sorry if my questions aren't very clear, or if I've overlooked something, but the last thing I'd want is to mess my scales up (and I'm just getting to grips with everything).

Thanks in advance.

Somebody must know the answer so I can return to map making.

10 3ds max units = 1 foot

Chief's height is 7.5 feet. 3ds max he is 75

thats how you scale, you can probably update the grid somehow too.

Halo to Real World Scale
As a reference, the Master Chief is approximately 7 feet tall.

This makes the unit scale approximately 10 units = 1 foot or about 1 unit = 1.2 inches.

Player Speed (world units/second)

Forward Movement Speed (Running): 2.25
Backwards Movement Speed (Running): 2.0
Side Strafe Movement Speed (Running): 2.0

I understand how to scale the objects and that now, but the way I did the actual size of the map was based on the travel times of existing maps and turning that into 'world units'. While I can always estimate the travel distance based on the information provided (I guess it's around 70 generic units a second), I'd prefer to be more accurate.

For example, my map was going to be 190 world units in length, and 85 in width. So, I then need to change those units into generic 3DS Max units.

So while converting generic 3DS Max units into real world scale is easy enough, I still haven't spotted what 'world units' are supposed to be.

Can anyone shed further light on this? =)

Edit: Apparently 1 world unit is equal to 100 generic 3DS Max units.

I did a quick check on this using the non scientific method of using MC's corpse to check the scale, film myself running past and then cutting the footage so it started as he ran past the corpse's head, and ended it exactly one second on.

If we take the apparent more accurate MC height of 7.5 feet, then we land at 225 3DS Max units, which would make that distance 2.25 world units per second, just as listed.

Given a slight margin of error, I guess 1 world unit is indeed 100 generic 3DS Max units, unless there's something else I've overlooked.

Holy Crap, Do some research why don't you.

This would make a good tut for people who have a hard time scaling (me).

Edit: 1 World Unit = 100 3ds max units make sense. 3 feet in 1 meter. about 2 meters in 1 world unit. Thats just a foot off. So really, its 2.333333333- meters in one world unit. Also, 10 units is 1 foot. So it would be about 10 feet in 1 world unit.
