NAME

       fs2_open - manual page for FreeSpace 2 Open

SYNOPSIS

       fs2_open

DESCRIPTION

       FreeSpace    2    Open   Website:   http://scp.indiegames.us   Mantis   (bug   reporting):
       http://scp.indiegames.us/mantis/

OPTIONS

       Usage: fs2_open [options]

Graphic:

       -spec  Enable specular

              Only polygons mapped with  textures  for  which  a  shinemap  exists  will  receive
              specular mapping; no attempt is made to generate spec maps where they do not exist.
              Specular maps are specified with the base map  name  plus  "-shine"  (i.e.  TCov3A-
              shine.pcx).

              FS2  Open,  3.6.15:  This  feature  is  on  by default, use launcher option Disable
              Specular or if necessary to manually disable enter the flag -nospec

       -glow  Enable glow maps

              Only polygons mapped with textures for which a glowmap exists will  be  glowmapped.
              Glow maps are specified with the base map name plus "-glow" (i.e. TCov4A-glow.pcx)

              FS2  Open,  3.6.15: This feature is on by default, use launcher option Disable Glow
              Maps or if necessary to manually disable enter the flag -noglow

       -env   Enable environment maps

              It only works  if  -spec  is  also  set.  Environment  mapping  intensity  will  be
              determined from the shine map too (see Texturing for more info). See Video setup.

              FS2  Open,  3.6.15:  This  feature  is  on  by default, use launcher option Disable
              Environment Maps or if necessary to manually disable enter the flag -noenv

       -mipmap
              Enable mipmapping

              Causes for non-mipmapped textures to have  mipmaps  generated  within  the  GPU  on
              certain  kind  of  texture formats, (IIRC, DDS formatted textures with a power of 2
              size in both width and height). Since the use of already mipmapped DDS textures has
              become  common,  it  has  become  deprecated.  The quality of the generated mipmaps
              depends on each GPU and used driver. It is normally used with -img2dds flag.

       -nomotiondebris
              Disable motion debris

       -noscalevid
              Disable scale-to-window for movies

              Disables fullscreen scaling of video clips.

       -missile_lighting
              Apply lighting to missiles

       -normal
              Enable normal maps

              Normal maps require GLSL rendering, (see OpenGL Shaders (GLSL) for  further  info).
              It  needs  auxiliary  normal  maps  (the same name of the base map plus "-normal").
              DXT5_NM DDS format is needed. (Technical note: DXT5 will work, since only the GREEN
              and  ALPHA  channels  are read by the current shader system. One direction of lines
              goes into the GREEN channel, the other direction goes into the ALPHA  channel.  RED
              and  BLUE  can  be  either  base  gray  (#808080) or black. Usual practice is after
              creating the DXT5_NM, copy the RED channel to the ALPHA channel, black out the  RED
              and BLUE an then save as either a DXT5 or u8888 (uncompressed) DDS file.)

              FS2 Open, 3.6.15: This feature is on by default, use launcher option Disable Normal
              Maps or if necessary to manually disable enter the flag -nonormal

       -3dshockwave
              Enable 3D shockwaves

              This only has any effect when both a  2d  and  3d  shockwave  effect  are  present,
              otherwise the only available effect is used.

       -post_process
              Enable post processing

              enables  the  use  (if  present)  of  post-processing  effects  as  defined  by the
              post_process.tbl. Bloom usage has an additional cmdline  option  for  setting  it's
              value,  most  post  processing  effects  are  achieved  in  mission per the mission
              designer or can be enabled globally in the table.

       -soft_particles
              Enable soft particles

       -fxaa  Enable FXAA anti-aliasing

              Enables the FXAA postprocessing stage. Needs optional FXAA shaders,  which  can  be
              found here: http://www.hard-light.net/forums/index.php?topic=76145.0

Game Speed:

       -img2dds
              Compress non-compressed images

              Converts  all  images  to  DDS  (compressed)  format.  Decreases  memory  usage but
              potentially reduces image quality.

       -no_vsync
              Disable vertical sync

       -cache_bitmaps
              Cache bitmaps between missions

              Will ideally reduce the load-time from one mission to another.

HUD:

       -dualscanlines
              Add another pair of scanning lines

              Adds a second pair of scanning lines to the target window when scanning an object.

       -targetinfo
              Enable info next to target

              Displays target info, such as name and class, beside the targeted object.

       -orbradar
              Enable 3D radar

              An Orb style 3D radar will replace the standard 2D version.

       -rearm_timer
              Enable rearm/repair completion timer

              Displays time remaining until rearm and repair from a support ship is complete.

       -ballistic_gauge
              Enable analog ballistic ammo gauge

              Adds an ammo gauge to the HUD when armed with a ballistic weapon.

Gameplay:

       -mod

              Specifies in which folders inside FreeSpace 2 directory, the game looks for all the
              game  data  (models,  missions,  textures,  tables, ...). Retail version only looks
              inside Freespace2/data/ structure and Freespace2/vp archives.

              This flag allows installing several different mods that modify retail behavior, and
              switching  between  them  without  needing to erase files or having undesired cross
              effects. Each mod should be installed in its own folder.

              It takes one argument string: the chain of names of the used directories. Comma (,)
              must  be  used  as  separator. In this way, -mod dir1,dir2,dir3,...,dirx causes the
              game to use the following directory precedence:

                  Freespace2/dir1/
                  Freespace2/dir2/
                  Freespace2/dir3/
                  ... (the rest of the typed directories) ...
                  Freespace2/dirx/
                  Freespace2/

              This flag can be indirectly set, (and it is normally set), through Launcher MOD tab
              and mod.ini file.

              Within the Launcher's MOD tab you can select one directory, (let's call it moddir),
              so the flag is at least set to -mod moddir. If Freespace2/moddir/mod.ini exists  it
              will be used to modify the -mod flag, too.

       -ship_choice_3d
              Use 3D models for ship selection

              Uses  ship models in ship selection window. It completely disables the standard ANI
              interface in this screen. Some mods need a compulsory use of this flag because they
              don't  have  available  animations for their ships. In this situation, and if it is
              not used, the game will probably crash to desktop in the ship selection window.

       -weapon_choice_3d
              Use 3D models for weapon selection

              Uses weapon models in weapon loadout window for  secondary  weapons  (missiles  and
              bombs). It completely disables the standard ANI interface in this screen. Some mods
              need a compulsory use of this flag because they don't have available animations for
              their  secondary  weapons.  In this situation, and if it is not used, the game will
              probably crash to desktop in the weapon loadout window.

       -3dwarp
              Enable 3D warp

              Use full geometry for the subspace warp effect.

       -warp_flash
              Enable flash upon warp

              Enable a flash at warp in and warp out.

       -no_ap_interrupt
              Disable interrupting autopilot

              Tells the game to not allow players to interrupt an autopilot already-in-progress.

Audio:

       -snd_preload
              Preload mission game sounds

              Useful in preventing game stuttering when sounds are played for the first time.

       -nosound
              Disable all sound

       -nomusic
              Disable music

Multiplayer:

       -standalone
              Run as standalone server

              Creates a standalone multi-player server.

       -startgame
              Skip mainhall and start hosting

              Once you launch and choose a pilot within the game, you will immediately have begun
              to  host  a game. This can be used in conjunction with several options to customize
              the game you create: -closed, -restricted, -password, -gamename,  -allowabove,  and
              -allowbelow. -startgame has no effect when -standalone is used.

              See related: -closed -restricted -password -gamename -allowabove -allowbelow

       -closed
              Start hosted server as closed

              Hosts a new game in a closed state, where no one can join until the in-game "Close"
              button is cleared. This only works when used in conjunction with -startgame. Cannot
              be used in conjunction with -restricted or -password.

              See related: -startgame -restricted -password

       -restricted
              Host confirms join requests

              Hosts a new game in a restricted state. The host is presented with option to accept
              or deny each client's request to join the  game.  This  only  works  when  used  in
              conjunction  with  -startgame.  Cannot  be  used  in  conjunction  with  -closed or
              -password.

              See related: -startgame -closed -password

       -multilog

              Creates a log file with a summary of  packets  sent  and  received  in  multiplayer
              games.  The  file  is saved as atalti.log within the active mod folder—or with main
              data folder if no mod is active.

       -clientdamage
              This feature is not available in current builds.

       -mpnoreturn
              Disable flight deck option

              Disables return to the flight deck screen after a mission completes.

Troubleshooting:

       -nohtl Software mode (very slow)

              Reverts to software rendering mode.   Warning:  Enabling  this  will  significantly
              reduce performance.

       -no_set_gamma
              Disable setting of gamma

              Disables the gamma settings in the options screen.

       -nomovies
              Disable video playback

              Disables all video playback.

       -noparseerrors
              Disable parsing errors

              Disables some parsing warnings and makes other parse errors non-fatal.  Do not rely
              on this when creating new tables. The errors are there for a reason.

       -query_speech
              Check if this build has speech

              Determines if the current build includes text-to-speech.

       -novbo Disable OpenGL VBO

       -noibx Don't use cached index buffers (IBX)

              Disables IBX caching of model geometry data. This will dramatically  increase  load
              times, but will help troubleshoot a model if one is working incorrectly.

       -loadallweps
              Load all weapons, even those not used

       -disable_fbo
              Disable OpenGL RenderTargets

       -no_glsl
              Disable GLSL (shader) support

              Disables the use of GLSL rendering (OpenGL shaders). The game will revert to legacy
              fixed render pipeline. Please note that Normal  and  Height  map  effects  will  be
              unavailable.

       -ati_swap
              Fix colour issues on some ATI cards

       -no_3d_sound
              Use only 2D/stereo for sound effects

       -disable_glsl_model
              Don't use shaders for model rendering

       -use_gldrawelements
              Don't use glDrawRangeElements

Experimental:

       -ingame_join
              Allow in-game joining

       -voicer
              Enable voice recognition

              Windows-only.  Enables voice-recognition for wingmen commands. Must be specifically
              compiled into a build in order for it to be available; 3.6.10  final  includes  the
              feature. See Voice Recognition for more details.

       -fb_explosions
              Enable Framebuffer Shockwaves

Development Tools:

       -fps   Show frames per second on HUD

              Displays current frames per second.

       -pos   Show position of camera

              Displays current position coordinates of camera.

       -window
              Run in window

              Runs  the game in a window. No check to make sure that resolution is no higher than
              your desktop resolution, so be careful.

       -stats Show statistics

              Shows total and free physical memory, virtual memory and system pagefile.

       -coords
              Show coordinates

              Shows coordinates of the mouse cursor.

       -show_mem_usage
              Show memory usage

              Shows detailed RAM usage based on file, handler and process usage  and  display  on
              the left-center side of the screen during mission load and while in mission.

              The meaning of the info displayed in the upper right corner of the HUD is:

              DYN  =  dynamic memory, basically anything that's been allocated by the vm_* memory
              functions. This does NOT indicate total memory usage but does account for  most  of
              it.

              POF  =  model  memory,  how  much  memory is being used by models (does not include
              textures)

              C-BMP, BMP = bmpman memory, how much  is  used  by  the  textures/images  that  are
              loaded.  C-BMP  means  that  you  are  using -cache_bitmaps and it will try to keep
              textures in memory between level loads and as the new level is loading it will keep
              what it needs and unload what it doesn't. Can greatly increase level loading speed,
              but does so at the cost of memory between  level  loads.  This  does  not  increase
              overall  memory  usage though, only during the loading screen. BMP means that it is
              not cached and all textures are unloaded from memory at the start of level load and
              all needed textures are then loaded from the disk again.

              S-RAM  = sound memory, how much is used by the sounds loaded in memory at the time.
              This counts static sounds only (from sounds.tbl, etc.)  and  not  streaming  sounds
              (music, voices, briefing stuff, etc).

              V-RAM  =  approximate  memory usage of video textures. This does not mean that your
              card has this much memory, and can report higher numbers that  your  card  actually
              has  memory. For OpenGL it also includes some of the geometry data, but this number
              does not reflect the total memory that your video card is using.  It  only  reports
              how much data the game has purposefully loaded into API memory (meaning it could be
              in system memory, video card memory, or AGP memory).

              (It only works with debug builds, not with release builds).

       -pofspew

              Reads all objects in the pof file of the selected mod, and  creates  an  ibx  cache
              file  for  each  object  in  the  data/cache folder for that mod.  Details for each
              object are output to a pofspew.txt file created in the data folder. Otherwise,  ibx
              files are created in game before each mission.

       -tablecrcs

              Is  actually  now (or should be) a typed reference rather than as a selection item.
              Takes 1 argument, usually a descriptive name. Example usage: "-table_crcs MediaVPs"
              will  create  a table_crcs.csv file in the running mod (name can be separate of the
              mod selected) that allows for the validation of the tables used by that  mod  while
              on-line. The descriptive parameter given helps "allocate" that .csv file to the mod
              in question, and as such  should  closely  or  exactly  match  that  mods  name  if
              possible.

       -missioncrcs

              Is  actually  now (or should be) a typed reference rather than as a selection item.
              Takes 1  argument,  usually  a  descriptive  name.  Example  usage:  "-mission_crcs
              MediaVPs"  will  create  a  mission_crcs.csv  file  in the running mod (name can be
              separate of the mod selected) that allows for the validation of the  missions  used
              by  that  mod  while on-line. The descriptive parameter given helps "allocate" that
              .csv file to the mod in question, and as such should closely or exactly match  that
              mods name if possible.

       -dis_collisions
              Disable collisions

       -dis_weapons
              Disable weapon rendering

       -output_sexps
              Output SEXPs to sexps.html

              This  will  make  the  FSO build spit out an html file that documents the supported
              SEXP's.

              Just double click on sexps.html and it should open in your default web browser.

       -output_scripting
              Output scripting to scripting.html

              This will make the FSO build spit out an html file  that  documents  the  supported
              scripting hooks and LUA libraries.

              Just double click on scripting.html and it should open in your default web browser.

       -save_render_target
              Save render targets to file

       -debug_window
              Display debug window

              Lists the fs2_open.log in (nearly)real-time generation.

       -verify_vps
              Spew VP CRCs to vp_crcs.txt

              Exports the CRC values of the VP files being loaded into a vp_crcs.txt file.

       -nograb
              Don't grab mouse/keyboard in a window

              Unix only. Disables focus grabbing in a window.
