File Description

Here is the GTA Garage Mod Manager, a program that is capable of installing Car packages for easy distribution and ease of use for GTA III, GTA Vice City and GTA San Andreas. With this program you can preview any cars before you install with a fully controllable 3d view and, you can also view different colors, damage textures, low detail amongst other views.

This program requires GGM files to install cars however as these contain all of the important information to be installed.

Please Note: This Modification is not hosted on FileFront servers.

extract the archive files into your gta installation directory (gta3, vice city or san andreas), this enables you to use the program with several games at once.

the ggmm.exe, gtainterface.dll and ggmm.txt should be IN exact same folder as gta3.exe, gta-vc.exe or gta_sa.exe

after you install it, click the help "?" button on program and set file association for .GGM files

important note !!
!!!!!!! only one program can control the file asociation at once !!!!!!!

program requirements:
- this program requires at least geforce3 class graphical card (but older may still work)
- a decent graphical card with DXT/S3TC support for gta-vc and gta-sa
- GL_EXT_texture_env_combine driver extension for displaying reflection maps correctly in opengl graphical driver
- gfx card should have at least 4 texture units for multitexturing
- one MB of disk space per installation
- windows 2000 or xp or 2003, win98 untested (may work, maybe not..)
- currently no testing was made on windows vista, if it doesn't work don't use vista.
- should run under linux / wine
- reactos is not yet at a stage for ggmm to work ;)



Version 1.7 build: 270805:

- added: some work was done on internal data editor, but it is not availible in this release.

- fixed: SA BMX now renders properly
- fixed: VC Flatbed now renders properly
- fixed: changed tractor and combine big wheel hack so now only tractor and combine have big wheels
- fixed: carmods.dat issuse should be fixed altrough i was unable to reproduce this error.

Version 1.5 build: 140805:

- added: additional handling lines like for helicopters and bikes are now supported in GGMM packages and manual car installer
- added: hirerarchy items now have checkboxes which you can uncheck and ggmm won't draw that object branch, this works with dummies too, also a note that this won't work right always, sometimes special rules apply on how gta draws things (like san andreas wheels) and so for some objects it might not work
- added: you can now control orientation of misc_a and misc_b objects
- added: you can now package weapons, but the packages don't contain weapon.dat information
- added: you can make backups of weapons
- added: the program checks if it is installed properly, if not it gives you hints on how to install it.
- added: if you on manual car installer enter colors data for car that has no color information the color information will be ADDED to colors file.

- fixed: vicecity helicopters no longer have wheels on them
- fixed: vicecity bikes now have proper wheel sizes
- fixed: you can no longer "edit" text displayed when installing ggm mods
- fixed: if you left some data to the manual car installer empty the validation mistakenly cleared some fields, now it doesn't do this anymore.

Version 1.4b (080805):
- added: option to show dummies (best viewed in wireframe mode because dummies are always drawn solid)
- added: option to disable reflections completely (sometimes the chrome is too shiny, and sometimes ATI cards couldn't handle it properly)

- fixed: solid faces no longer cut through transparent faces (and opposite). the program now draws model in 2 passes, there could be still glitches if your car happens to have transparent wheels..
- fixed: in gta3 some cars had a dummy named "steeringwheel_dummy" and GGMM accidently drawn a wheel on the dummy because it thought it is a wheel dummy, now it doesn't do that anymore.

Version 1.4a (070805):
- added: refreshes data after manual car installing
- added: propeller blades and bike wheels now also animate
- added: you can now do a little car "show-off" using object rotations in model information window (open doors, etc..)

Version 1.4 (060805):
- added: new improved program look / skin by Tank
- added: manual car installer has a validate button, the configuration is also validated when you click install button.
- added: in san andreas now shows chrome reflections (used by Linerunner, some cars and some boats) (requires GL_EXT_texture_env_combine opengl extension to look properly)
- added: in san andreas mode you can now view second uv map (may be little glitchy) (requires GL_EXT_texture_env_combine opengl extension to look properly)
- added: shininess specular sphere-maps are now displayed (in san andreas) but not in vice city yet (requires GL_EXT_texture_env_combine opengl extension to look properly)

- fixed: zmodeler 1.x cars show their normals correctly now.

Version 1.3a (050805):
- added: icons to menus and hirerarchy viewer (blue things are dummies, silver are geometry objects)
- added: model details window now shows amout of triangles and vertices rendered
- added: right clicking on car list now selects the car before showing popup menu
- added: car popup menu has a item for instant backup creation for any car

- fixed: zmodeler2 dffs now load properly
- fixed: if san andreas wheel object was not named wheel or wheel2 then it was not rendered, now the program uses object under wheel_rf_dummy for san andreas wheels just like the game does.

Version 1.3 (040805):
- added: gta3 and vice city cars now show with wheels
- added: cars are shown shiny using normals from the cars themseles
- added: program can read gta-vc speca and san andreas reflection maps (altrough i don't know how to use them properly so they would look like ingame)

- fixed: no more missing cars and wierd objects, cars are displayed the way they should without need for reloading
- fixed: every time you reloaded the car list was filled with doubles, now it doesn't do that anymore
- fixed: gta3 car rendering now works properly
- fixed: sometimes you could see thru cars where transparent objects were, now in those cases the transparency is not displayed so the view is better altrough this needs a proper object sorting fix

opposite of the features added & fixed this version of program is now actually smaller than before!

Version 1.2 (030805):
- added: backup system, when you first time install a package the original car will be packaged and put into CarBackups folder which will be created - note that when using manual car installer no backups are made because program doesn't know which car you are installing (because you can for example install data line for landstalker, dff file for infernus and txd for tank..)
- added: carmods.dat file packaging support, packages and program are ofcourse backwards compatible just that older versions will not know how to handle carmods line and will skip that data when installing ggm files
- added: more safety checking when installing .ggm mods

- fixed: sometimes if you didn't enter IDE line into manual car installer the san andreas game wasn't properly detected

Version 1.1 (020805):
- added: search box, while you type text the text the program automaticly searches the list and selects first item that contains the searched text
- added: several checks for detecting if gta game is running in background which may cause problems
- added: more checking when installing .ggm mods
- added: drag & drop on main window, you can drag & drop a ggm file into main window to install it.

- fixed: window flickering while resizing has been eliminated
- fixed: cars with 4 colors in carcols.dat now show 3 colors correctly (prim, sec, ter..), color 4 is never used afaik so i don't know how to use it



- you can specify coll file in manual car installer for san andreas too, if you do that it will be merged with dff model, if dff already has a coll chunk it will replace it.
- altrough main window is oddly-shaped it is resizable
- you can also view weapon models (no packaging availible yet)
- mods are packaged together with description / readme text
- the browser doesn't work yet but it will download and install mods one day
- the program works for gta3, vice city and san andreas
- the GGM files are already pretty well compressed and contain a readme.txt text that is displayed when installing mods, so you shouldn't double compress the ggm files to archieve better compression (rar might gain approx 10 kb) or to include a readme file.


Known problems

- The mod browser doesn't work (yet)
- 3D renderer's background sometimes doesn't look nice when the window is resized
- when resizing the window the model is not displayed until you drop the sizing grip, this problem is not too serious but i hope to fix it one day.
- the model is sometimes not rendered right, just reload the model (may take several times)
- no wheels are rendered in vice city and gta3 mode, you will see red boxes instead.



The program was programmed in 2005 by Jernej L. (Delfi) for
