The batch file I created must be used to start up
blood in 3dfx. You MUST allready have the 3dfx patch installed.
You can edit the batch file by yourself by rightclicking on it
and the select "edit".
When you edit it you see the start up file at the end, the 3dfx.exe.
This is the exe file from the 3dfx pathc from blood. If you named it
differently change the name in the batch file also, else it won't
start up.
The batch file will work with voodoografics and with voodoo2 boards.
There still is a bug with the voodoo2 board, you may get an error
wich says that it ran out of texture memory for the current textures.
Hmmm, but it's stil fun to play, just save often and restart the game.
You may try to run it with a voodoo3 board, maybe it will work too!.
I hope you enjoy it.





Here is some detailed info about the 3dfx build stuff.
I got it from the shadow warrior 3dfx pacth.


Environment Variables
---------------------
The BUILD_640X480 environment variable is used
to run the game in the 640x480 resolution.  
The default setting is 0, and the default resolution
is 512x384.
e.g. set BUILD_640x480=1

The BUILD_RESAMPLE environment variable is used
to control how the game and animation textures
are converted to 3Dfx format.  If you set this
variable, the slower method of sampling and blending
is used.  This gives a more desirable image however
it takes a long time to run, and it gives a dark
halo effect surrounding sprites (i.e. the fists
and some menu bar things).  The faster way uses
point sampling, it provides a more grainy conversion,
but is a lot faster than the previous method.  
You only need to convert the textures the first time
you run the program, and if you want to recreate
them, delete the "tx3dfx" and animxxxx directories
which contain all the .3df files.

The BUILD_BRIGHTNESS environment variable is used to 
brighten the colors of the textures that are used in
the game engine.  The colors will be brightened by this
factor, and will saturate to white.  The default setting
is 2.5.  
e.g. set BUILD_BRIGHTNESS=2.8

The BUILD_NOPAL environment variable is used to turn
on palette downloading on a per-span basis.  
!!!Warning!!! This will affect the color palette of the game
and the colors may not be correct!  This is only provided
as a speed boost.  The default setting is 0.
e.g. set BUILD_NOPAL=1

The BUILD_NOFOG environment variable allows the game
fog to be turned on/off.  This is provided as a
speed boost.  The default setting is 0.
e.g. set BUILD_NOFOG=1

The BUILD_CONVTEXTURES environment variable is used
to control whether or not textures are cached to disk.
If BUILD_CONVTEXTURES is set to 1, then the textures
will not be cached to disk and will be converted in
memory.  If you are running the game under Windows 95,
then this setting is not recommended. If you are
running the game under DOS, then this setting may help
out because disk I/O access is slower on some
DOS machines than others.  The default setting is 0.
e.g. set BUILD_CONVTEXTURES=1

The BUILD_TRICOUNT environment variable shows the number
of triangles drawn in the last frame.  The default setting
is 0.
e.g. set BUILD_TRICOUNT=1

The BUILD_FPS environment variable shows the current clock
settings, frame number, and a (rough)FPS count.  
The default setting is 0. 
e.g. set BUILD_FPS=1

The BUILD_VERSION environment variable shows the current
version number of the 3Dfx Version of the Build Engine
and the current version of Glide you are using below that.
The default setting is 0.
e.g set BUILD_VERSION=1

BUILD_MRED, BUILD_MGREEN, BUILD_MBLUE set the colors
of mirrors in the game respectively.  Their range is
from 0-255.  Their default settings are 200, 200, and 255
respectively (gives a blue tinge to all mirrors)
e.g. for dark blue mirrors:
   set BUILD_MRED=0
   set BUILD_MGREEN=0
   set BUILD_MBLUE=200
