Always snap to grid
On UT, UZ files are used to store packages under compressed form on redirection sites. These redirection sites provide a faster means for a client to download packages a server needs and avoids hindering the overall performance of a server. They seem to use the Huffman codec which is also used by the WinZip standard.
For example to redirect a map on your own UT server:
- Take an UNR map.
- Optionally embed it with any media used, such as UAX sounds, UMX music or UTX textures.
- Use the Ucc tool to convert the map to a UZ package; "UCC compress mapname.unr". Use "UCC help" for more information.
- Place the file in a redirection location on the web (with preferably fast upstream).
- In the file "UnrealTournament.ini", under section "[IpDrv.HTTPDownLoad]", add this location behind "RedirectToURL=", for example: "RedirectToURL=http://www.domain.com/folder/" (and make sure "UseCompression" is set to "True" (default)).
