qbsp − Compile a Quake BSP file from a MAP source file
qbsp [OPTION]... SOURCFILE [DESTFILE]
qbsp is a tool used in the creation of maps for the id Software game Quake. qbsp takes a .map file as input and produces a .bsp file playable in the Quake engine. If the DESTFILE argument is not supplied, the output filename will be chosen by stripping the file extension (if any) from SOURCEFILE and appending the .bsp extension.
−nofill
Doesn’t perform outside filling
−noclip
Doesn’t build clip hulls
−noskip
Doesn’t remove faces using the ’skip’ texture
−onlyents
Only updates .map entities
−verbose
Print out more .map information
−noverbose
Print out almost no information at all
−splitspecial
Doesn’t combine sky and water faces into one large face
−transwater
Computes portal information for transparent water (default)
−notranswater
Computes portal information for opaque water
−transsky
Computes portal information for transparent sky
−oldaxis
Uses original qbsp texture alignment algorithm
−forcegoodtree (experimental)
Force use of expensive processing for SolidBSP stage. Often results in a more optimal BSP file in terms of file size, at the expense of extra processing time.
−bspleak
Creates a .por file, used in the BSP editor
−oldleak
Create an old-style QBSP .PTS file (default is new)
−nopercent
Prevents output of percent completion information
|
−bsp2 |
Create the output BSP file in BSP2 format. Allows the creation of much larger and more complex maps than the original BSP 29 format). | ||
|
−2psb |
Create the output BSP file in 2PSB format. This an earlier version of the BSP2 format, supported by the RMQ engine (and thus is also known as the BSP2rmq or RMQe bsp format). original BSP 29 format). |
−leakdist [n]
Space between leakfile points (default 2)
−subdivide [n]
Use different texture subdivision (default 240)
−wadpath <dir>
Search this directory for wad files (default is cwd)
The contents inside a brush depend on the texture name(s) assigned to it.
By default brush contents are solid unless they have a special name. Names beginning with an asterisk are liquids. A prefix of *slime indicates slime, *lava is for lava and anything else beginning with * will have contents as water.
All faces of a brush must have textures which indicate the same contents. Mixed content types will cause qbsp to print an error and exit.
SKIP
Any surfaces assigned a texture name of skip will be
compiled into the bsp as invisible surfaces. Solid surfaces
will still be solid (e.g. the play can’t walk or shoot
through them) but they will not be drawn. Water, slime and
lava surfaces can be made invisible using the texture names
*waterskip, *slimeskip and *lavaskip
respectively.
HINT
Hint surfaces cause a bsp split and portal to be generated
the on the surface plane, after which they are removed from
the final bsp - they are neither visible, nor structural.
Strategic placement of hint surfaces can be used by a map
author to optimise the PVS calculations so as to limit
overdraw by the engine (see also: vis(1)).
Use a texture with the name hintskip on any surfaces of a hint brush which you don’t want to generate bsp splits or portals. All surfaces of a hint brush must use either the hint or hintskip texture name.
This version of qbsp supports detail brushes which are similar in concept to Quake 2’s detail brushes.
To be compatible with existing Quake 1 mapping tools, detail brushes can be added by creating an entity with classname "func_detail". When qbsp reads the map file, it will add any brushes included in a func_detail entity into the worldspawn as details and remove the func_detail entity. Any number of func_detail entities can be used (useful for grouping) and all included brushes will be added to the worldspawn.
Here is an example entity definition suitable to add the the .QC files used by BSP Editor:
/*QUAKED
func_detail (0.5 0.5 0.9) ?
Detail brushes add visual details to
the world, but do not block visibility.
func_detail entities are merged into
the worldspawn entity by the qbsp compiler
and do not appear as separate entities in
the compiled bsp.
*/
For WorldCraft in .FGD format (untested):
@SolidClass color(128 128 230) = func_detail: "Detail" []
For Radiant in .ENT format:
<group
name="func_detail" color="0 .5 .8">
Detail brushes add visual details to the world, but do not
block visibility. func_detail entities are merged into the
worldspawn entity by the qbsp compiler and do not appear as
separate entities in the compiled bsp.
</group>
What should be written to the .map file is a simple entity with one or more brushes. E.g.:
{
"classname" "func_detail"
{
( -176 80 0 ) ( -208 80 0 ) ( -208 48 0 ) COP1_1 0 0 0 1.0
1.0
( -192 -80 64 ) ( -208 -80 0 ) ( -192 -64 64 ) COP1_1 0 0 0
1.0 1.0
( -176 -80 0 ) ( -192 -80 64 ) ( -176 -64 0 ) COP1_1 0 0 0
1.0 1.0
( -16 48 0 ) ( -16 64 64 ) ( 0 48 0 ) COP1_1 0 0 0 1.0 1.0
( -16 64 64 ) ( -16 80 0 ) ( 0 64 64 ) COP1_1 0 0 0 1.0 1.0
}
}
When qbsp detects detail brushes, it outputs a modified portal file format with the header PRT2 (default is PRT1). This portal file contains extra information needed by vis to compute the potentially visible set (PVS) for the map/bsp. So you will also need a vis util capable of processing the PRT2 file format.
In addition to standard Quake 1 .map files, TyrUtils QBSP is compatible with:
|
• |
Floating point brush coordinates and texture alignments | ||
|
• |
Valve’s 220 map format as produced by the Hammer editor | ||
|
• |
Extended texture positioning as supported by the QuArK editor | ||
|
• |
Standard Quake 2 map format (leading paths in texture names are stripped and any extra surface properties are ignored) |
