Visible surfaces are not subdivided as required by shader tesselation.
|
|||
|

The shader parameter "tesssize" sets the tesselation of a surface.

-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
|

|
|
than necesary.
|
|||
|

|

-nosort

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.
|
|||
|
|
-bounce <N> [NEW]
|
|||
|
|
Enable radiosity calculation. Rediffuses the light emitted onto surfaces N
|
|||
|
|
times. Will write out the BSP after every pass, so it can be cancelled.
|
|||
|
|
Light reflected is the lightmap/vertex * texture color, subsampled to a certain
|
|||
|
|
granularity across every lit surface. Use q3map_lightimage in a shader
|
|||
|
|
to override the reflected color.
|
|||
|
|
-bouncegrid [NEW]
|
|||
|
|
Radiosity affects lightgrid (entity lighting).
|
|||
|
|
-fast [NEW]
|
|||
|
|
Enables light envelopes for area lights, speeding light up by 50x or more on
|
|||
|
|
some maps. Has the side effect of dimmer maps with large numbers of dim surface
|
|||
|
|
lights.
|
|||
|
|
-fastgrid [NEW]
|
|||
|
|
Same as fast, but only for lightgrid calculation.
|
|||
|
|
-fastbounce [NEW]
|
|||
|
|
Enables fast for radiosity passes only.
|
|||
|
|
-cheap [NEW]
|
|||
|
|
Stop calculating light at a sample when it exceeds (255, 255, 255). This may
|
|||
|
|
produce odd artifacts on maps with lots of saturated colored lighting. Also,
|
|||
|
|
do not use -cheap with radiosity if you wish to preserve all light emitted.
|
|||
|
|
-cheapgrid [NEW]
|
|||
|
|
Same as cheap, but only for lightgrid calculation.
|
|||
|
|
-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.
|
|||
|
|
-smooth [NEW]
|
|||
|
|
Smart version of -extra. Only subsamples lightmap pixels that are shadowed.
|
|||
|
|
Produces results comparable to -extra in roughly 1/3 the time. Can also be
|
|||
|
|
used with -extra or -extrawide for 16- or 48-tap sampling respectively
|
|||
|
|
(smoother shadows).
|
|||
|
|
-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.
|
|||
|
|

|
|||
|
|

|
|||
|
|
-v

|
|||
|
|
-nosurf
|
|||
|
|
Disables surface tracing (detail brushes and patches) for shadow calculation.
|
|||
|
|
-dump
|
|||
|
|
Dumps prefab files when used with radiosity for each bounce.
|
|||

|
|
The light goes through or not and does not change color.
|
|||
|
|
-tracelight
|
|||
|
|
Use the "-light" light algorithm for all surface unless a surface
|
|||
|
|
uses a shader with the shader option "q3map_vlight".
|
|||
|
|
-samplesize <N>

|
|
<p><font size="3">q3map_vertexshadows</font></p>

<p><font size="3"> [<font color="#FFFF00">NEW</font>] By default, no shadows are cast on vertex-only lit surfaces (see
|

|
|
surfaceparm pointlight). Also when running Quake III Arena in vertex lighting
|
|||
|
|
mode, no shadows are cast upon any surfaces (shadows are part of the light map).
|
|||
|
|
When using this shader option shadows *will* be cast on the surface when vertex
|
|||
|
|
lit. However sharp shadow edges won't be seen on the surface because light
|

|
|
values are only calculated at the vertexes.</font></p>

|
|||
|
|
q3map_novertexshadows to disable shadows to be cast at the vertex lit surfaces.
|

|
|
Shadows being cast at small misc_model objects often makes sense. However
|
|||
|
|
shadows on large vertex lit terrain surfaces often look bad. By default no
|

shadows are cast at forced vertex list surfaces ( shaders with "pointlight"

).</font></p>

<p>With the new q3map tool you can add custom surface parameters for mods

without the need to recompile the q3map tool. These custom surfaceparms are
|
|||
|
|
stored in a file called <20>custinfoparms.txt<78> in the folder scripts/. An

|

example of this file with the new surfaceparm treacle and surfaceparm grass is

first looks in your homedir, and only if it doesn't find a custinfoparms.txt

<p>Content Flags</p>
|
|||
|
|
</b><font SIZE="2">
|
|||
|
|
<p>Contents flags are flags similar to CONTENTS_FOG in the original Q3A. These
|
|||
|
|
flags define the contents of volumes inside the game (for instance lava, fog,
|
|||
|
|
water, etc.).</p>
|
|||
|
|
<p>If you look in the source file game/surfaceflags.h, it has defines for all
|
|||
|
|
contents flags. The define is split into a name and a hexadecimal value, for
|
|||
|
|
instance CONTENTS_PLAYERCLIP 0x10000. These hexadecimal values are powers of 2
|
|||
|
|
and can be ored together (binary) to form a bit mask. Up to 32 contents flags
|
|||
|
|
can be ored together this way.</p>
|
|||
|
|
<b>
|
|||
|
|
<p>Example</b>: creating a volume with treacle.</p>
|
|||
|
|
<p>The following outlines how a custom contents flag can be added and used in a
|
|||
|
|
mod. First open the <20>custinfoparms.txt<78> file and add <20>treacle 0x4000<30>
|
|||
|
|
to the Custom Contentsflags section as shown in the example file above (0x4000
|
|||
|
|
is one of the unused values available for custom use). Next write a shader
|
|||
|
|
script which uses <20>surfaceparm treacle<6C>. Apply this new shader to all sides
|
|||
|
|
of a brush in a test map. When you compile the map, add the -custinfoparms
|
|||
|
|
parameter to the command line following q3map.</p>
|
|||
|
|
<p>Next, add CONTENTS_TREACLE 0x4000 to the source file game/surfaceflags.h in
|
|||
|
|
your mod. Now you can call the point contents function. If the point is inside
|
|||
|
|
the brush with the shader using the <20>surfaceparm treacle<6C> then the point
|
|||
|
|
contents call will return a bit mask with CONTENTS_TREACLE set. This can for
|
|||
|
|
instance be used to slow down player movement when a player is inside such a
|
|||
|
|
brush.</p>

<p>Surface Flags</p>
|
|||
|
|
</b><font SIZE="2">
|
|||
|
|
<p>The surface flags are texture properties that often affect entities in
|
|||
|
|
contact with surfaces using such flags. The <20>surfaceparm metalsteps<70>
|
|||
|
|
parameter from Q3A is a good example.</p>
|
|||
|
|
<p>If you look in the source file game/surfaceflags.h, it has defines for all
|
|||
|
|
surface flags. The define is split into a name and a hexadecimal value, for
|
|||
|
|
instance SURF_NODAMAGE 0x1. These hexadecimal values are powers of 2 and can be
|
|||
|
|
ored together (binary) to form a bit mask. Up to 32 surface flags can be ored
|
|||
|
|
together this way.</p>

|
|||
|
|
<p>Example</b>: Making <20>footsteps on grass<73> sounds</p>
|
|||
|
|
<p>The following outlines how a custom surface flag can be added and used in a
|
|||
|
|
mod. First open up the <20>custinfoparms.txt<78> file and add 'grass 0x80000' to
|
|||
|
|
the Custom Surfaceflags section as shown in the example file above (0x80000 is
|
|||
|
|
the first available unused value in surfaceflags.h for surface flags). Next
|
|||
|
|
write a shader script which uses a grass image and has 'surfaceparm grass<73>.
|
|||
|
|
Create a test map with the grass shader covering the ground surface. When you
|
|||
|
|
compile the map, add the -custinfoparms parameter to the command line following
|
|||
|
|
q3map.</p>
|
|||
|
|
<p>Next, add SURF_GRASS 0x80000 to the source file game/surfaceflags.h in your
|
|||
|
|
mod. Now you'll be able to execute a trace and the trace information will be
|
|||
|
|
returned in the trace_t structure. If the trace hits a surface with the grass
|
|||
|
|
surfaceparm then the SURF_GRASS flag will be set in trace_t->surfaceFlags.
|
|||
|
|
Such a trace can be used to trigger playing a sound of a person stepping on
|
|||
|
|
grass. For a reference example, see the existing metal steps in the game code.</p>
