View source for VBSP

A compiling tool that creates the [[BSP]] (Binary Space Partition) file that will be your map. Can be run by itself to create a (test) map, but the additional use of the other two tools ([[vvis]] and [[vrad]]) is recommended for release maps.

Vbsp also places [[Detail Props]] on appropriate surfaces in a map.

There are various command-line options that can be used in combination with [[expert compile mode]], a batch file, or directly at a Windows command prompt. For a complete list, envoke <code>%sourcesdk%\bin\vbsp.exe</code> at the commmand prompt, with no other parameters.

== Syntax ==
 vbsp [options...] mapfile

Example:

 %sourcesdk%\bin\vbsp.exe -onlyents sdk_trainstation_01

== Common options ==

; -v (or -verbose): Turn on verbose output (also shows more command-line options). Use without any other parameters.
;-onlyents : This option causes vbsp to only import the entities from the vmf-file. -onlyents won't reimport brush models.
;-onlyprops : Only update the static props and detail props.
;-glview : Writes .gl files in the current directory that can be viewed with glview.exe. If you use -tmpout, it will write the files into the \tmp folder.
;-nodetail : Get rid of all detail geometry. The geometry left over is what affects visibility.
;-nowater : Get rid of water brushes.
;-low : Run as an idle-priority process.
;-vproject <directory> : Override the VPROJECT environment variable.
;-game <directory> : Same as -vproject.

==Other options==
Run <code>%sourcesdk%\bin\vbsp.exe -v</code> to display these options. 

;-novconfig : Don't bring up graphical UI on vproject errors.
;-threads : Control the number of threads vbsp uses (defaults to the # of processors (times 2 for Hypertreading CPU's) on your machine).
;-verboseentities: If -v is on, this disables verbose output for submodels.
;-noweld : Don't join face vertexes together.
;-nocsg : Don't chop out intersecting brush areas.
;-noshare : Emit unique face edges instead of sharing them.
;-notjunc : Don't fixup t-junctions.
;-noopt : By default, vbsp removes the 'outer shell' of the map, which are all the faces you can't see because you can never get outside the map. -noopt disables this behavior.
;-noprune : Don't prune neighboring solid nodes.
;-nomerge : Don't merge together chopped faces on nodes.
;-nomergewater: Don't merge together chopped faces on water.
;-nosubdiv : Don't subdivide faces for lightmapping.
;-micro <#> : vbsp will warn when brushes are output with a volume less than this number (default: 1.0).
;-fulldetail : Mark all detail geometry as normal geometry (so all detail geometry will affect visibility).
;-leaktest : Stop processing the map if a leak is detected. Whether or not this flag is set, a leak file will be written out at <vmf filename>.lin, and it can be imported into Hammer.
;-bumpall : Force all surfaces to be bump mapped.
;-snapaxial : Snap axial planes to integer coordinates.
;-block # # : Control the grid size mins that vbsp chops the level on.
;-blocks # # # # : Enter the mins and maxs for the grid size vbsp uses.
;-dumpstaticprops: Dump static props to staticprop*.txt
;-dumpcollide : Write files with collision info.
;-luxelscale # : Scale all lightmaps by this amount (default: 1.0).
;-lightifmissing : Force lightmaps to be generated for all surfaces even if they don't need lightmaps.
;-keepstalezip : Keep the BSP's zip files intact but regenerate everything else.
;-xbox : Enable mandatory xbox optionsm (Can cause memory leeks on Windows with out applying the patch code to your mod found at [[SDK_Known_Issues_List]])
;-replacematerials : Substitute materials according to materialsub.txt in content\maps
;-FullMinidumps : Write large minidumps on crash.

==Nonfunctional Options==
;-linuxdata : Force it to write physics data for linux multiplayer servers. ( It will automatically write this data if it finds certain entities like info_player_terrorist, info_player_deathmatch, info_player_teamspawn, info_player_axis, or info_player_coop. )
;-nolinuxdata : Force it to not write physics data for linux multiplayer servers, even if there are multiplayer entities in the map.
;-virtualdispphysics : Use virtual (not precomputed) displacement collision models
