Map dimensions question - need a Devs input

(Hakuryu) #1

I’m working on a Maya tutorial for creating terrain, and trying to put alot of information in it, but I found a problem while trying to explain sizes. After combing interviews I could only find a reference to ‘a square mile’ when describing the map dimensions, but this doesnt seem to match other facts I have.

We know that terrains start out as a 32768 square plane, and since 1 unit == 1 inch, this ends up being only 1/2 square mile ((32768/12)/5280 = 0.52).

Could any dev please enlighten me as to actual map sizes, and if they are bigger than 1/2 mile, then does this mean some maps start out as 65536 square or are multiple terrain meshes used in a single map? I’m trying to make a good tutorial, and really could use this information.

As far as i know it’s not 32K units / inches.
It’s 32K pixels.
It has been mentioned in one of the latest videos (again?).
And I think I’ve read it in one of the posts here in the forum before.
Not sure how pixels are related to gameunits.

The 32k pixels is only for the megatexture.

It’s been stated many times that 1 game unit equals 1 inch or 2.5 cm in Radiant editors by ID. I’ve seen people say SD has said the same thing, which makes sense since its basically the same engine, but havent found direct quotes of this.

After more searching, I’ve found Paul Wedgewood saying ‘1 square kilometer’ which is 0.62 miles, which about equals my math in figuring out the size of a 32k plane. The ‘square mile’ references I have found have been in interviews, and the interviewer may have interpreted km as miles for some reason.
