q3map
-----

-threads <number>
	Number of threads used to compile the map. For the fastest compile
	times the number of threads is set to the number of system processors.
-glview
	Write a .gl file of the bsp tree for debugging.
-v
	Output verbose information.
-draw
	Enable realtime debug drawing output.
-nowater
	Water, slime and lava brushes are not compiled and won't show up when running the map in Quake.
-noopt
	unused.
-nofill
	unused.
-nodetail
	Detail brushes are not compiled and won't show up when running the map in Quake.
-fulldetail
	Detail brushes will be treated as normal brushes.
-onlyents
	Only change the entities in a .bsp using a .ent file.
-onlytextures
	Only change the textures in a .bsp file.
-micro
	unused.
-nofog
	Visible surfaces that cross fog boundaries will not be split along the bound.
	This can cause visually incorrect fog in the map.
-nosubdivide
	Visible surfaces are not subdivided as required by shader tesselation.
	The shader parameter "tesssize" sets the tesselation of a surface.
-leaktest
	Only test the map for leaks. If a leak is found the compilation is stopped.
-verboseentities
	Output verbose information about entity sub-models.
-nocurves
	Curves are not compiled and won't show up when running the map in Quake.
-notjunc
	T-junctions are not fixed. This can cause tiny slits where a brush meets halfway another brush.
-expand
	Expands all the brush planes and saves a new map out to allow visual inspection of the clipping bevels
-tmpout
	Output files to a folder called "tmp".
-fakemap
	Write out a fakemap.map This map will contain a worldspawn entity with all the world brushes.
-samplesize <N>
	Set the lightmap pixel size to NxN units. Default 16x16.


q3map -vis
----------

-threads <number>
	Number of threads used to compile the map. For the fastest compile
	times the number of threads is set to the number of system processors.
-fast
	Only calculate a very loose visiblity list. It doesn't take much time to
	calculate but a lot more polygons will be drawn by the Q3 engine than necesary.
-merge
	Merge bsp leaves before calculating the visibility list. This will speed up
	the vis calculations but mostly more polygons will be drawn by the Q3 engine
	than necesary.
-nopassage
	Disable the passage visibility algorithm. The passage vis is faster and a bit more
	tight than the default algorithm.
-level
	unused.
-v
	Output verbose information.
-nosort
	Don't sort the portals on complexity. Sorting mostly speeds up visibility calculations
	because more complex portals can use information from less complex portals.
-saveprt
	Don't delete the .prt file after creating the visibility list.
-tmpin <path>
	Input files will be read from a folder called "tmp".
-tmpout <path>
	Output files will be written to a folder called "tmp".


q3map -light
------------

-threads <number>
	Number of threads used to compile the map. For the fastest compile
	times the number of threads is set to the number of system processors.
-area <scale>
	This scales the light intensity of area lights.
-point <scale>
	This scales the light intensity of point lights.
-notrace
	No light tracing is performed. As a result no shadows will be casted.
-patchshadows
	Enable patches casting shadows.
-novertex
	Don't calculate vertex lighting.
-nogrid
	Don't calculate light grid for dynamic model lighting.
-extra
	Take four samples per lightmap pixel and store the average light value of these
	four samples for the actual lightmap pixel.
	This super sampling is used for anti-aliasing.
-extrawide
	Just like -extra four samples per lightmap pixel are calculated. However the
	average of 12 samples is stored per lightmap pixel.
-samplesize <N>
	Set the lightmap pixel size to NxN units. Default 16x16.
-border
	Create a debugging border around the lightmap.
-v
	Output verbose information.
-nosurf
	unused.
-dump
	unused.


q3map -vlight
-------------

-threads <number>
	Number of threads used to compile the map. For the fastest compile
	times the number of threads is set to the number of system processors.
-area <scale>
	This scales the light intensity of area lights.
-point <scale>
	This scales the light intensity of point lights.
-novertex
	Don't calculate vertex lighting.
-nogrid
	Don't calculate light grid for dynamic model lighting.
-nostitching
	No polygon stitching before lighting.
-noalphashading
	Don't use alpha shading.
-nocolorshading
	Don't use colored alpha shading.
-samplesize <N>
	Set the lightmap pixel size to NxN units. Default 16x16.
-v
	Output verbose information.
