What is mapsize?

If you look at the *.def file for a Quake 4 multi player map it has a section similar to the text below;

"size0"  "130932507"
"size1"  "130932507"
"size2"  "130970639"
"size3"  "444323314"

This is the mapsize data. The game uses this information so it knows how much memory the map and it's assets take up when loaded into Quake 4. Although for the most part it doesn't appear to be uber necessary for custom maps it's always a good idea (and good practice) to generate the data whenever possible.

How do I create mapsize data?

To create the mapsize data you need to use a special *.bat file (a file that can be 'executed' in a similar wat to the Quake 4 short cut icon) that contains a number of cvar commands and the path/name of the map the data needs to be generated for. The file is saved to the games asset folder; q4base/ and then executed from there (double click on the file).

Creating mapsize.bat

Copy, paste and amend the following text so it points to your Quake 4 map; change the name and folder location where appropriate (make sure you use the correct file path),

@echo off
cd..
quake4.exe +com_updateloadSize 1 +si_map mp/kat_q4dm1.map +si_pure 0 +spawnserver +wait

Then save the file as mapsize.bat to the q4base (or your mod) folder. You should end up with a path to the bat file similar to this;

Quake 4/q4base/mapsize.bat

Once in place double click the file to execute it. Quake 4 should open and the map being referenced should load. Close Quake 4. If you then find the maps *.def file (in the def folder) you should have a new or ammended entry there; size0 to 4 will have been updated or changed depending on what quality settings you were just running the game at.

Rinse and repeat for each quality setting

You can download mapsize_bat.zip from here if you have problems copy/pasting the text above. Simply extract or drag and drop the file to your q4base folder and use as described above.
